This article studies the conditions of social reception of managed retreat as a response to coastal flooding, by risk managers (elected officials and agents) in Camargue and Normandy, through a participatory simulation conducted during workshops. After defining the notion of social reception chosen in relation to acceptability, the process of building reception through the participants’ player actions is described. The variety of forms of understanding that managers have of managed retreat and the temporal dimension are highlighted. Other factors of reception are then revealed (political context, social representations, perception of management scales) based on the analysis of the territorial discourses of the participants during the workshops. Through the parallels between game and reality, the study highlights the factors that determine the social reception of public policies for coastal risk management in each territory studied.

Industrial accidents are a major risk in many countries. Despite this observation, effective preventive action is not being developed and studies of the behaviors of vulnerable populations remain under-explored. According to safety instructions, residents must take shelter and remain indoors but other behaviors may be observed such as: running away from the affected area, panicking, or following people around. In order to assess the attitudes of people and the effects of local contingencies that could interfere with official advice in the event of a toxic cloud, a specific agent-based model called TOXI-CITY has been developed. The aim of this explorative model is to determine whether a minimum number of well-informed agents (i.e. those who follow the emergency protocol) can save a maximum number of uninformed and impressionable ones. Simulations indicate that the initial number of agents and the spatial configuration of the grid strongly influence final survival rates. A non-linear pattern emerged: survival rates increase when well-informed agent rates are low (below 30%) while increasing the percentage of informed agents (from 70%) seems to improve only slightly the chances of survival.

In this work we address the issue of sustainable cities by focusing on one of their very central components: daily mobility. Indeed, if cities can be interpreted as spatial organizations allowing social interactions, the number of daily movements needed to reach this goal is continuously increasing. Therefore, improving urban accessibility merely results in increasing traffic and its negative externalities (congestion, accidents, pollution, noise, etc.), while eventually reducing the quality of life of people in the city. This is why several urban-transport policies are implemented in order to reduce individual mobility impacts while maintaining equitable access to the city. This challenge is however non-trivial and therefore we propose to investigate this issue from the complex systems point of view. The real spatial-temporal urban accessibility of citizens cannot be approximated just by focusing on space and implies taking into account the space-time activity patterns of individuals, in a more dynamic way. Thus, given the importance of local interactions in such a perspective, an agent based approach seems to be a relevant solution. This kind of individual based and “interactionist” approach allows us to explore the possible impact of individual behaviors on the overall dynamics of the city but also the possible impact of global measures on individual behaviors. In this paper, we give an overview of the Miro Project and then focus on the GaMiroD model design from real data analysis to model exploration tuned by transportation-oriented scenarios. Among them, we start with the the impact of a LEZ (Low Emission Zone) in the city center.

- Abstract
The estimation of seismic damages and debris at the urban scale - at a precise building-by-building level- is challenging for several reasons. First, commonly used methodologies for seismic damage estimation rarely take into account the local site effects, precisely at the building-level. Second, the available methods for debris estimation fail to estimate at the same time the quantity of debris generated per building according to its damage level and the distribution of the debris (extent and height) around buildings. Finally, the lack of comprehensive data on the building stock and the relevant building properties and their taxonomy further increases the complexity of assessing possible earthquake consequences at an urban scale. This paper addresses these challenges and proposes improvements to the assessment of seismic damages and debris at the building level, along with the development of a 3D building model based on satellite images and heterogeneous data. These developments, applied to the city of Beirut, Lebanon, highlight the control of the site effects on the seismic damage spatial distribution throughout the city and the large volume and extent of debris to be expected in the city for a strong earthquake.

International audience; The Le Teil earthquake (south France, 11-11-2019, Mw 4.9, 1 km depth, about 4 km of surface ruptures) was felt at a distance up to about 300 km. In order to estimate the EMS98 intensity in each of the affected localities, we collected macroseismic observations via individual forms filled in by citizens (2094 testimonies) or collective forms filled by authorities (388 localities) and by field survey work in the epicentral zone (24 most damaged cities). Field observations and communal surveys remain essential in the case of structural damage. Intensities deduced from public surveys are preliminary and their consideration in the final estimates must be limited. The maximum intensity observed is VII-VIII in Le Teil and 30 localities experienced an intensity ≥ VI. The earthquake generated damage (I ≥ V) up to about 50 km away and was felt in at least 568 localities.

International audience; On November 11, 2019, a Mw 4.9 earthquake hit the region close to Montelimar (lower Rhône Valley, France), on the eastern margin of the Massif Central close to the external part of the Alps. Occuring in a moderate seismicity area, this earthquake is remarkable for its very shallow focal depth (between 1 and 3 km), its magnitude, and the moderate to large damages it produced in several villages. InSAR interferograms indicated a shallow rupture about 4 km long reaching the surface and the reactivation of the ancient NE–SW La Rouvière normal fault in reverse faulting in agreement with the present-day E–W compressional tectonics. The peculiarity of this earthquake together with a poor coverage of the epicentral region by permanent seismological and geodetic stations triggered the mobilisation of the French post-seismic unit and the broad French scientific community from various institutions, with the deployment of geophysical instruments (seismological and geodesic stations), geological field surveys, and field evaluation of the intensity of the earthquake. Within 7 days after the mainshock, 47 seismological stations were deployed in the epicentral area to improve the Le Teil aftershocks locations relative to the French permanent seismological network (RESIF), monitor the temporal and spatial evolution of microearthquakes close to the fault plane and temporal evolution of the seismic response of 3 damaged historical buildings, and to study suspected site effects and their influence in the distribution of seismic damage. This seismological dataset, completed by data owned by different institutions, was integrated in a homogeneous archive and distributed through FDSN web services by the RESIF data center. This dataset, together with observations of surface rupture evidences, geologic, geodetic and satellite data, will help to unravel the causes and rupture mechanism of this earthquake, and contribute to account in seismic hazard assessment for earthquakes along the major regional Cévenne fault system in a context of present-day compressional tectonics.

International audience; The attractiveness and urbanisation of coastal zones increase their vulnerability to climate change and sea-level rise, in particular to flooding and marine erosion. In the face of the projected increase in losses and damages, the anticipation and measures needed for adaptation involve physical, socioeconomic and political dimensions at different governance levels and timescales. A large literature addresses these various issues, generally in a targeted way. Drawing on adaptive policy pathways approaches and on research results of the past decade in mainland France, this article proposes an interdisciplinary characterisation of long-term adaptation pathways in coastal areas. Among the different variables and processes of change that characterise coastal zones and their future, particular emphasis is placed on social and institutional dynamics. This work contributes to the debate about adaptive governance in a highly uncertain context as well as to recent work to explore pathways and tipping points in support of climate adaptation policies.

BCSF-RéNaSS (Bureau central sismologique français – Réseau national de surveillance sismique) manages the collection of data from the field for any earthquake in mainland France of magnitude greater than 3.7 and ensures their interpretation in terms of macro-seismic intensities (severity of ground shaking) on EMS98, European Macroseismic Scale (Grünthal, 1998). Unlike the magnitude, which is calculated from seismological records, the intensity of the tremor is only known in each location by analysing the observable effects on people, objects and structures. In case of damage, the GIM (Groupe d'intervention macrosismique = Macroseismic Response Group), coordinated by the BCSF-RéNaSS, establishes EMS98 intensities within a short time after the occurrence of the earthquake. It gathers together scientists (researchers and engineers in tectonics, geology, civil engineering, etc.) from various French scientific institutions.The 2019-11-11 Le Teil earthquake of magnitude ML 5.2 occurred at 10h52 UTC, 11h52 local time. It is a very shallow event, with hypocentre at about 2km depth and a fault rupture that reached the surface. More than 2000 people who felt the tremor responded to the online survey via the www.franceseisme.fr website, allowing a preliminary and rapid estimation of the intensity of the tremor. The day after the event, the BCSF-RéNaSS launched a survey toward the municipal authorities using a collective form designed for the town halls of the municipalities potentially affected. Given the damage described in the answers, the GIM was mobilized to accurately assess the EMS98 intensities of municipalities near the epicentre, based on the effects observed on buildings, people and objects, and taking into account their vulnerability.Among the almost sixty experts that compose the GIM, seven from IRSN, ISTerre/RESIF-RAP, Cerema, Pacte/UGA, IPGS and EOST/BCSF-RéNaSS answered the call. Divided into teams of 2 or 3, they inspected 24 municipalities between November 18thand 22nd, assisted by mayors or municipal services and sometimes accompanied by the rescue brigade. Several hundred buildings of different vulnerabilities were inspected.In most cases, many cracks, sometimes significant and open, were observed. Few of the oldest structures built mostly in the 19thcentury, associated to vulnerability A, partially or totally collapsed in the most affected areas such as Le Teil and Viviers. For comparable buildings, more severe damages were observed on top of hills (Saint-Thomé) or on sedimentary filling (Savasse) which attests for local site effects. The highest intensities reach locally VIII in La Rouvière and Mélas, two neighbourhood of Le Teil, that are located the closest to the Rouvière fault. These are the highest intensities observed in mainland France since the Arette earthquake in 1967 (Rothé, 1972).The macroseismic intensities EMS98, estimated during the GIM's field missions, are one of the major input on which is based the decision of the French commission to classify municipalities in a state of natural disasters. That decision triggers insurance coverage of damages. Over the 24 analysed by the GIM, the commission classified 19 municipalities during their meetings of November 20thand December 11th. Following commission meetings will examine the other impacted municipalities.

Since its creation in the late 1990s, UNISDR has identified education and knowledge as priority factors for risk and disaster reduction, notably through Hyogo and Sendai frameworks for actions. More recently, the 2019 Assises Nationales des Risques Naturels (a major meeting event organized by the French Ministry of Ecology on the natural risks management) have pointed out the urgent need to develop a risk culture to improve the resilience of territories. One of the levers for developing this risk culture is to inform the population of the risks to which they are exposed. Preventive information can take a wide variety of forms: regulatory brochures, exhibitions, plays, etc. However, we can wonder about the impact of this information: is it effective? Does it reach its objectives? How to evaluate its influence?In a geographical context where few natural disasters occur, questionnaire surveys can be a solution. However, several studies have shown that this method fails to put individuals in a situation of emergency and to project themselves into a potential event that they may have difficulties to imagine. This is why the I²PRI project proposes to go beyond these methods and develop innovative and immersive tools to assess the impact of preventive information on people's knowledge. The project developed both a video game and a play. The objective of these media is to immerse the respondents in a fictive but realistic disaster situation in order to evaluate their ability to mobilize their knowledge in the case of a real event. Those tools are based on a common scenario that aims at putting the respondents in a dilemma situation. They mobilize an artistic dimension and raise the question of how to transcribe natural events through sound and visual stimuli or through interactions with other characters. Each tool has an observation and a debriefing phase which allow not only to analyse the respondents reactions but also to assess the efficiency of the whole protocol.Applied to two phenomena (fast kinetic floods and earthquakes), the survey has been carried out in six municipalities of the French Alps. Those municipalities are characterized by different geographical contexts (urban/rural, plain/mountain) and different preventive information contexts (old information, regulatory information, alternative information). The talk will present the two protocols and the first results of their deployment in the field: the results of the survey about the level of information of the population, the side effects of the protocols in terms of preventive action, and the action-based research process in terms of public action of preventive information.

International audience; For some scientific questions, empirical data are essential to develop reliable simulation models. These data usually come from different sources with diverse and heterogeneous formats. The design of complex data-driven models is often shaped by the structure of the data available in research projects. Hence, applying such models to other case studies requires either to get similar data or to transform new data to fit the model inputs. It is the case of agent-based models (ABMs) that use advanced data structures such as Geographic Information Systems data. We faced this problem in the LittoSIM-GEN project when generalizing our participatory flooding model (LittoSIM) to new territories. From this experience, we provide a mapping approach to structure, describe, and automatize the integration of geospatial data into ABMs.

The locus coeruleus–norepinephrine system is thought to be involved in the clinical effects of vagus nerve stimulation. This system is known to prevent seizure development and induce long-term plastic changes, particularly with the release of norepinephrine in the hippocampus. However, the requisites to become responder to the therapy and the mechanisms of action are still under investigation. Using MRI, we assessed the structural and functional characteristics of the locus coeruleus and microstructural properties of locus coeruleus-hippocampus white matter tracts in patients with drug-resistant epilepsy responding or not to the therapy. Twenty-three drug-resistant epileptic patients with cervical vagus nerve stimulation were recruited for this pilot study, including 13 responders or partial responders and 10 non-responders. A dedicated structural MRI acquisition allowed in vivo localization of the locus coeruleus and computation of its contrast (an accepted marker of LC integrity). Locus coeruleus activity was estimated using functional MRI during an auditory oddball task. Finally, multi-shell diffusion MRI was used to estimate the structural properties of locus coeruleus-hippocampus tracts. These characteristics were compared between responders/partial responders and non-responders and their association with therapy duration was also explored. In patients with a better response to the therapy, trends toward a lower activity and a higher contrast were found in the left medial and right caudal portions of the locus coeruleus, respectively. An increased locus coeruleus contrast, bilaterally over its medial portions, correlated with duration of the treatment. Finally, a higher integrity of locus coeruleus-hippocampus connections was found in patients with a better response to the treatment. These new insights into the neurobiology of vagus nerve stimulation may provide novel markers of the response to the treatment and may reflect neuroplasticity effects occurring in the brain following the implantation.

Biology (General) ,QH301-705.5 - Abstract
Abstract Exposure to blue wavelength light stimulates alertness and performance by modulating a widespread set of task-dependent cortical and subcortical areas. How light affects the crosstalk between brain areas to trigger this stimulating effect is not established. Here we record the brain activity of 19 healthy young participants (24.05±2.63; 12 women) while they complete an auditory attentional task in darkness or under an active (blue-enriched) or a control (orange) light, in an ultra-high-field 7 Tesla MRI scanner. We test if light modulates the effective connectivity between an area of the posterior associative thalamus, encompassing the pulvinar, and the intraparietal sulcus (IPS), key areas in the regulation of attention. We find that only the blue-enriched light strengthens the connection from the posterior thalamus to the IPS. To the best of our knowledge, our results provide the first empirical data supporting that blue wavelength light affects ongoing non-visual cognitive activity by modulating task-dependent information flow from subcortical to cortical areas.

Human behaviour during crisis evacuations is social in nature. In particular, social attachment theory posits that proximity of familiar people, places, objects, etc., promotes calm and a feeling of safety, while their absence triggers panic or flight. In closely bonded groups such as families, members seek each other and evacuate as one. This makes attachment bonds necessary in the development of realistic models of mobility during crises. This article presents a review of evacuation behaviour, theories on social attachment, crisis mobility, and agent-based models. It was found that social attachment influences mobility in the different stages of evacuation (pre, during and post). Based on these findings, a multi-agent model of mobility during seismic crises (SOLACE) is being developed, and it is implemented using the belief, desire and intention (BDI) agent architecture.

Aging ,Neuroscience ,Medicine - Abstract
BACKGROUND The locus coeruleus (LC) is the primary source of norepinephrine in the brain and regulates arousal and sleep. Animal research shows that it plays important roles in the transition between sleep and wakefulness, and between slow wave sleep and rapid eye movement sleep (REMS). It is unclear, however, whether the activity of the LC predicts sleep variability in humans.METHODS We used 7-Tesla functional MRI, sleep electroencephalography (EEG), and a sleep questionnaire to test whether the LC activity during wakefulness was associated with sleep quality in 33 healthy younger (~22 years old; 28 women, 5 men) and 19 older (~61 years old; 14 women, 5 men) individuals.RESULTS We found that, in older but not in younger participants, higher LC activity, as probed during an auditory attentional task, was associated with worse subjective sleep quality and with lower power over the EEG theta band during REMS. The results remained robust even when accounting for the age-related changes in the integrity of the LC.CONCLUSION These findings suggest that LC activity correlates with the perception of the sleep quality and an essential oscillatory mode of REMS, and we found that the LC may be an important target in the treatment of sleep- and age-related diseases.FUNDING This work was supported by Fonds National de la Recherche Scientifique (FRS-FNRS, T.0242.19 & J. 0222.20), Action de Recherche Concertée – Fédération Wallonie-Bruxelles (ARC SLEEPDEM 17/27-09), Fondation Recherche Alzheimer (SAO-FRA 2019/0025), ULiège, and European Regional Development Fund (Radiomed & Biomed-Hub).

International audience; Earthquake damage and loss scenarios are considered as a powerful tool to help in the design of efficient seismic mitigation policies. Moreover, at a city scale, adequate urban planning may significantly contribute to improve resilience through requalification of inherited urban fabrics and/or appropriate land use. In this perspective, the present paper investigates what could be the optimal graphic representation of probable losses at urban scale, which be most relevant for seismic risk management. The goal is to provide urban planners with guidelines on how to combine the use of vulnerability index-based damage estimates and GIS tools, to identify urban fabrics that need requalification. The proposed methodology consists in starting from damage estimates at the individual building scale and using GIS (Geographic Information Systems) capacities to aggregate the expected damage on neighborhoods of increasing size, from blocks to large urban districts, in order to delimitate homogeneous urban zones. The criteria thus for choosing the optimal aggregation level are based on the need to obtain legible maps combining robust damage estimations ? which implies statistics over a large enough number of buildings ?, and a clear identification of the most vulnerable urban areas on which dedicated actions should be focused in priority.These methodologies are presented and tested on the example of the city of Oran (Algeria), and on the basis of a prior vulnerability study based on GNDT and RISK-UE vulnerability index approaches. The main outcome is the identification of different urban zones, which exhibit some homogeneity regarding both their average seismic response and their urban function. The most vulnerable urban fabrics require not only individual retrofitting measures at building scale; they also need urban requalification because it is more convenient to deal simultaneously with urban and safety considerations.

International audience; The theory of social attachment states that individuals seek the proximity of attachment figures (e.g. family members, friends, colleagues, familiar places or objects) when faced with threat. During disasters, this means that family members may seek each other before evacuating, gather personal property before heading to familiar exits and places, or follow groups/crowds, etc. This hard-wired human tendency should be considered in the assessment of risk and the formulation of disaster management plans. Doing so may result in more realistic evacuation procedures and may minimise the number of casualties and injuries. In this context, a dynamic spatio-temporal analysis of seismic risk is presented here using SOLACE, a multi-agent model of pedestrian behaviour based on the theory of social attachment applied using the Belief-Desire-Intention approach. The model focuses on the influence of human, social, physical and temporal factors on successful evacuation. Human factors considered include perception and mobility defined by age. Social factors are defined by attachment bonds, social groups, population distribution, and cultural norms. Physical factors refer to the location of the epicentre of the earthquake, the spatial distribution/layout and attributes of environmental objects such as buildings, roads, barriers (cars), placement of safe areas, evacuation routes, and the resulting debris/damage from the earthquake. Experiments tested the influence of time of the day, the presence of disabled persons and earthquake intensity. Initial results show that factors that influence arrivals in safe areas include (a) human factors (age, disability, speed), (b) pre-evacuation behaviours, (c) perception distance (social attachment, time of day), (d) social interaction during evacuation, and (e) physical and spatial aspects, such as limitations imposed by debris (damage), and the distance to safe areas. To validate the results, scenarios have to be designed with stakeholders, who would also take part in the definition of a serious game. The recommendation of this research is that both social and physical aspects must be considered when defining vulnerability in risk analysis.

International audience; Due to the increase in coastal flooding risk associated with sea-level rise and increasing population along the coasts, there is a strong need to develop efficient and long-term management strategies. In partnership with the local administration of Oléron Island in France, a participatory simulation model was developed to foster social learning about coastal risk prevention measures with local authorities and managers. This simulation integrates a coastal flooding model and a spatially explicit agent-based model that simulates the development of the area and the management of prevention measures. The participatory set-up includes an immersive environment for participants to remember the coastal flooding simulation displayed and a role game mechanism that simulates the coordination issues between the different decision bodies involved in coastal risk management. A first application proved that participants learn about the water expansion dynamics during flood events and the effects of building, raising and restoring dikes.

The earthquake which struck the city of Lorca, Spain, on 11 May 2011 killed 9 people, injured over 300 and caused considerable damage, including one collapsed building. Streets near buildings were the main danger areas for people. This article proposes an dynamic ad hoc spatio-Temporal method for studying individual evacuation after an earthquake. Its application to the Lorca case shows the spatial and temporal variability of individual exposure levels in the street during the hours following the shock. As yet little studied, human exposure deserves more attention, particularly in zones of moderate seismicity like the Euro-Mediterranean area. The results of this study could be helpful for enhancing the evacuation planning after an earthquake, stressing the specific dangers in the street. Fil: Bertran Rojo, Marc.

In the context of a growing demand from citizens to be involved in decisions concerning the land use planning, there is a need to modernize the processes of participation, in particular through the development of digital practices. Audiovisual media is a desired approach and this article proposes to study its uses as well as its potential contributions to geography and planning. To this end, various audiovisual productions by geographers, as well as articles presenting them, have been studied. The degree of scientificity and creativity that the films must include raises questions about their legitimacy. Nevertheless, they seem to be an effective means of proposing a detailed analysis of the territory and of what citizens have to say. They bring new points of view to the spectator by allowing them to take a position. However, the use of films in land use planning would seem to be conditioned by the fact that their trajectory must be more closely correlated to that of the territory, which is generally filmed at a given moment, i.e. before and/or after transformation/processing, which does not allow citizens to participate in all stages of the land use planning.

IntroductionThe brainstem locus coeruleus (LC) influences a broad range of brain processes, including cognition. The so-called LC contrast is an accepted marker of the integrity of the LC that consists of a local hyperintensity on specific Magnetic Resonance Imaging (MRI) structural images. The small size of the LC has, however, rendered its functional characterization difficult in humans, including in aging. A full characterization of the structural and functional characteristics of the LC in healthy young and late middle-aged individuals is needed to determine the potential roles of the LC in different medical conditions. Here, we wanted to determine whether the activation of the LC in a mismatch negativity task changes in aging and whether the LC functional response was associated to the LC contrast.MethodsWe used Ultra-High Field (UHF) 7-Tesla functional MRI (fMRI) to record brain response during an auditory oddball task in 53 healthy volunteers, including 34 younger (age: 22.15y ± 3.27; 29 women) and 19 late middle-aged (age: 61.05y ± 5.3; 14 women) individuals.ResultsWhole-brain analyses confirmed brain responses in the typical cortical and subcortical regions previously associated with mismatch negativity. When focusing on the brainstem, we found a significant response in the rostral part of the LC probability mask generated based on individual LC images. Although bilateral, the activation was more extensive in the left LC. Individual LC activity was not significantly different between young and late middle-aged individuals. Importantly, while the LC contrast was higher in older individuals, the functional response of the LC was not significantly associated with its contrast.DiscussionThese findings may suggest that the age-related alterations of the LC structural integrity may not be related to changes in its functional response. The results further suggest that LC responses may remain stable in healthy individuals aged 20 to 70.

Environmental science - Abstract
The Lorca earthquake (Spain, 11-05-2011) caused considerable damages, including a building collapse. This earthquake killed 9 persons affected outside the buildings, on the street, and more than 300 people injured. Studying this specific human exposure requires an adapted methodolgy. This article proposes a dynamic and spatio-temporal approach of individual mobility during the seismic crisis. Its application on Lorca case shows spatial and temporal variability of individual exposure level in the street during the hours following the shake. Not really studied until now, this specific human exposure deserves more attention particularly in zones of moderate seismicity, like Euromediterranean area.

Social vulnerability has been studied for years with sociological, psychological and economical approaches. Our proposition focuses on perception and cognitive representations of risks by city dwellers living in a medium size urban area, namely Mulhouse (France). Perception, being part of the social vulnerability and resilience of the society to disasters, influences the potential damage; for example it leads to adequate or inadequate behaviour in the case of an emergency. As geographers, we assume that the spatial relationship to danger or hazard can be an important factor of vulnerability and we feel that the spatial dimension is a challenging question either for better knowledge or for operational reasons (e.g. management of preventive information). We interviewed 491 people, inhabitants and workers, regularly distributed within the urban area to get to know their opinion on hazards and security measures better. We designed and mapped a vulnerability index on the basis of their answers. The results show that the social vulnerability depends on the type of hazard, and that the distance to the source of danger influences the vulnerability, especially for hazards with a precise location (industrial for example). Moreover, the effectiveness of the information campaigns is doubtful, as the people living close to hazardous industries (target of specific preventive information) are surprisingly more vulnerable and less aware of industrial risk.

This paper is concerned with the development of an agent-based model of population behaviour during a bushfire, to form the basis of a simulator that will be used as a decision-support tool for emergency managers. To ensure the validity of the simulation results, it is essential that the model, and the underlying agent architecture, are as realistic as possible. After providing some context about recent bushfires in Victoria, Australia, we justify the need for a BDI (belief, desire, intention) agent architecture. Although some tools exist to support the integration of such agents in simulations, they are infrequently used. We therefore show how an existing methodology for modelling military tactics can be adapted to this context. The contribution of this paper is two-fold: providing an agent-based model of population behaviour during bushfires; and presenting a methodology that can be used by other model designers in the field of crisis management.

This study aims at developing a generic model of crisis mobility based on two case studies in Lebanon and Argentina. The research is characterised by a strong interdisciplinary cooperation between geographers, psychologists and computer scientists. The objective of the model is to show how appropriate human behaviours can reduce fatalities. The paper presents the methodology used in both case studies, some results of the Lebanese model as well as lessons from Lebanon to be applied to Argentinian study (on-going work). The methodology consists in field studies, model design, development, validation/calibration and simulation. The simulation aims at reproducing survey results as well as investigating new scenarios.

International audience; The city of Oran is exposed to a significant seismic hazard, as almost all the northern Algeria territory, where numerous casualties and severe damage occurred in the last decades due to several moderate to large earthquakes. A mitigation policy should include the establishment of priorities to reduce the vulnerability of existing buildings based on the knowledge of the actual urban fabrics. The complexity of vulnerability assessment requires a gradual approach from the urban scale to the building scale. The study reported in this paper corresponds to the first step of such an approach, i.e., a preliminary study of the seismic vulnerability and expected damage within an urban district of the city of Oran, based on a non-dedicated data base from a building survey previously performed for other purposes. The main goals of this study are twofold: (1) an assessment of the degree of uncertainty and robustness of such results through a comparison of the results derived from different urban vulnerability methods (GNDT 2; RISK-UE LM1; and VULNERALP 2.0) and (2) an assessment of the actual level of seismic risk in the city of Oran. Cross-method comparisons and correlations highlight a satisfactory agreement between mean damage estimates at the urban scale, despite significant scattering at the single building scale, and uncertainty levels which vary significantly from one method to the other. For a given scenario, the three methods provide damage estimates lying within half an EMS damage degree of one another, with some systematic positive bias for VULNERALP and negative bias for RISK-UE LM1, especially for masonry buildings. The expected mean damage is very important for intensities 9 and 10, with an average damage grade around 3-4 for intensity 9 and 4-5 for intensity 10. The spatial distribution of damage systematically exhibits larger values in the northern, older, commercial area, than in the southern, more recent and more residential area, in relation to the building typology and the existence of several aggravating factors. Some areas of higher vulnerability / damage can be distinguished, which should receive particular attention for retrofitting priorities or urban planning decisions, also taking into account their cultural heritage value.
