BackgroundDigital health tools comprise a wide range of technologies to support health processes. The potential of these technologies to effectively support health care transformation is widely accepted. However, wide scale implementation is uneven among countries and regions. Identification of common factors facilitating and hampering the implementation process may be useful for future policy recommendations. ObjectiveThe aim of this study was to analyze the implementation of digital health tools to support health care and social care services, as well as to facilitate the longitudinal assessment of these services, in 17 selected integrated chronic care (ICC) programs from 8 European countries. MethodsA program analysis based on thick descriptions—including document examinations and semistructured interviews with relevant stakeholders—of ICC programs in Austria, Croatia, Germany, Hungary, the Netherlands, Norway, Spain, and the United Kingdom was performed. A total of 233 stakeholders (ie, professionals, providers, patients, carers, and policymakers) were interviewed from November 2014 to September 2016. The overarching analysis focused on the use of digital health tools and program assessment strategies. ResultsSupporting digital health tools are implemented in all countries, but different levels of maturity were observed among the programs. Only few ICC programs have well-established strategies for a comprehensive longitudinal assessment. There is a strong relationship between maturity of digital health and proper evaluation strategies of integrated care. ConclusionsNotwithstanding the heterogeneity of the results across countries, most programs aim to evolve toward a digital transformation of integrated care, including implementation of comprehensive assessment strategies. It is widely accepted that the evolution of digital health tools alongside clear policies toward their adoption will facilitate regional uptake and scale-up of services with embedded digital health tools. more...

- Abstract
We present the detection and localization of local seismic events from a seismic network consisting of more than 350 short-period and broadband stations deployed in the Eifel volcanic region, centered around the Laacher See. The network spans an area of 180 km by 120 km. Using a combination of stacking and migration method and characteristic function generated by a re-trained neural network which are imaging P and S wave phase arrivals, we are able to detect and automatically locate seismicity in the network from continuous waveform data, including those events associated with dormant volcanic processes. The Eifel region has been geologically active for millions of years, with the most recent volcanic explosive eruption 13,000 years ago at the Laacher See. While the area is currently considered volcanic dormant, the ongoing seismic activity provides insight into the magmatic activity at depth. Our results can help to improve our understanding of the transcrustal magmatic system beneath intraplate volcanic fields and potential for future volcanic activity in the Eifel. The method and example presented here can be applied to volcanic provinces elsewhere support volcanic monitoring and fast, automatic processing of seismicity., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) more...

- Abstract
Highlights • We show the first observations of seismo-acoustic tremor at Oldoinyo Lengai, the world's only active carbonatite volcano. • We observe significant changes in seismic and acoustic tremor properties and their correlation in one year of data collection. • Using satellite-based thermal data, we identify different volcanic processes (degassing, lava pond dynamics and spattering). Abstract We analyze volcanic tremor from Oldoinyo Lengai, Tanzania, which is currently the only active volcano on Earth producing carbonatitic lavas. Here, we use data from the recent SEISVOL deployment and focus on a co-located seismic and infrasound station about 200 m below the summit. We show the very first observations of seismo-acoustic tremor caused by carbonatitic eruptions. This seismo-acoustic tremor is highly variable throughout the ∼one year of data which we characterize by analyzing its seismic amplitude, duration, recurrence, dominant seismic frequency and harmonics. Frequency gliding occurs frequently and over short (minutes to hours) to long time scales (hours to days) and likely reflects different time-dependent mechanisms, such as evenly-spaced repeating events with a change in inter-event times, crater dynamics that alter resonators, and dike intrusions. Seismic and acoustic wavefields correlate well for stronger eruptive sequences but are only partially coherent which suggests that high-frequency seismic tremor (up to 25 Hz) may be caused by the low viscosity of the carbonatitic melt and not by ground-coupled airwaves. In addition, the comparison between seismic-acoustic and satellite InfraRed thermal data allows us to infer different volcanic activity styles which partially alternate throughout the year: intrusive activity and the construction of hornitos, degassing, activity from a lava pond, and varying styles of extrusive activity, in particular spattering. Our study provides important insights into the eruption dynamics of this peculiar volcano which suggest more...

30. Volkswirtschaftliche Kosten von Demenz in Österreich

- Abstract
In Österreich sind geschätzt 147.000 Menschen von Demenz betroffen, wobei sich eine genaue Anzahl an Demenzerkrankten durch Unterdiagnostizierung und – damit teilweise einhergehend – Unterversorgung nicht feststellen lässt. Ziel der vorliegenden Studie ist es daher, einerseits zur Forschung in Bezug auf Kosten beizutragen, aber auch das Aus-maß der Belastung durch Demenz für Betroffene, deren Angehörige und letztlich für die gesamte Gesellschaft aufzuzeigen. Die Abschätzung der monetären Kosten in dieser Studie basiert einerseits auf demenz-attributablen Anteilen, andererseits werden intangible Kosten auf Basis von Ergebnissen internationaler Literatur diskutiert. Die Analyse der informellen Pflege erfolgt gemäß dem Substitutionskostenansatz und ergibt die gesamten (nicht demenz-attributablen) bewerteten Kosten der informellen Pflege aller zu Hause lebenden DemenzpatientIn-nen. Insgesamt belaufen sich die monetären Kosten auf EUR 2,7 Mrd. im Jahr 2019. Es wird geschätzt, dass 3,9 Prozent der laufenden Gesundheitsausgaben (ohne Langzeitpflege), 15,8 Prozent der Bruttoausgaben für stationäre Pflege und 22,5 Prozent der Bruttoaus-gaben für mobile Pflege im Jahr 2019 auf Demenz zurückzuführen sind. Hinzu kommen Kosten der informellen Pflege für jene DemenzpatientInnen, die zu Hause leben. Jene Kosten werden auf EUR 4,9 Mrd. inklusive Beaufsichtigungszeit bzw. EUR 3 Mrd. ohne Beaufsichtigungszeit geschätzt, wobei als Kostensatz der Marktwert einer formalen Pfle-gestunde herangezogen wurde. Die Studie zeigt somit auf, dass Demenz mit einer Vielzahl an Ausgaben im Gesundheits- und Langzeitpflegesektor im Zusammenhang steht. Die berechneten Kosten der infor-mellen Pflege verdeutlichen zudem den bedeutenden Anteil an Pflege- und Betreuungs-diensten, die von Angehörigen geleistet werden. Informelle Pflege geht jedoch darüber hinaus mit intangiblen Kosten einher, die von verlorener Freizeit, sozialer Isolation, De-pression bis hin zu einer Verschlechterung des eigenen Gesundheitszustands reichen, welche in weiterer Folge Risikofaktoren sind, selbst eine Demenz zu entwickeln. Demenzielle Erkrankungen werfen zunehmend Fragen auf, insbesondere in welcher Form Demenzerkrankte therapiert und versorgt werden können, und wie stark die Prä-valenz durch die Alterung der Bevölkerung in den kommenden Jahren steigen wird. Den-noch ist die Datenlage, die notwendig wäre, um im Konkreten die Versorgung und die Pflege dieser Menschen sicherzustellen, in Österreich – wie wir feststellen mussten – fragmentiert und bisher unzureichend. In Austria, an estimated 147,000 people have dementia, although underdiagnosis and – partly arising from this – underprovision of appropriate care do not allow to determine the exact number of dementia patients. Despite increasing relevance, evidence about dementia in Austria is sparse, particularly in the context of the economic costs of de-mentia. The aim of the study is to contribute to the stream of research about costs of dementia. We demonstrate the magnitude of the burden of the disease affecting pa-tients, caregivers, and the entire society. The study uses the approach of population dementia-attributable fractions; intangible costs are discussed based on international literature. The estimation of health costs in-cludes costs of dementia per se as well as dementia-attributable fractions of secondary diseases, calculated from relative risks from epidemiological studies. We transfer cost shares of the German disease-related cost accounts to Austrian health expenditures by age and sex. Dementia-attributable costs for residential, home, and live-in domestic care as well as for work loss of caregiving relatives rely on different data sources. The estima-tion of the costs of informal care, using a substitution approach, reflects total (not de-mentia-attributable) costs. The monetary costs of dementia for the year 2019 amount to a total of EUR 2,7 billion. About half of these costs are medical costs. Approximately 3.9 % of health care expend-itures (excl. long-term care), 15.8 % of residential care expenses and 22.5 % of home care expenses were attributable to dementia in 2019. The production loss due to re-duced working hours of caregiving relatives is estimated at EUR 31 million. In addition to monetary costs, total costs of informal care for dementia patients living at home account to EUR 4.9 billion including all supervision time or EUR 3.0 billion without supervision time. Dementia is associated with high expenditures in the health and long-term care sector, which are set to increase further in coming years due to the aging of the population. The magnitude of notional costs of informal care illustrates the substantial share of care work provided by relatives. Caregivers suffer from loss of free time, social isolation, de-pression, and poorer health in general, which are in turn risk factors for developing de-mentia themselves. Owing to the lack of data, the results are partly based on estimates and assumptions. An improvement of the data situation would be highly necessary in order to adequately plan care supply and its costs for the future, especially in the face of increasing demand. more...

We present the results of P-to-S receiver function analysis to improve the 3D image of the sedimentary layer, the upper crust, and lower crust in the Pannonian Basin area. The Pannonian Basin hosts deep sedimentary depocentres superimposed on a complex basement structure and it is surrounded by mountain belts. We processed waveforms from 221 three-component broadband seismological stations. As a result of the dense station coverage, we were able to achieve so far unprecedented spatial resolution in determining the velocity structure of the crust. We applied a three-fold quality control process; the first two being applied to the observed waveforms and the third to the calculated radial receiver functions. This work is the first comprehensive receiver function study of the entire region. To prepare the inversions, we performed station-wise H-Vp/Vs grid search, as well as Common Conversion Point migration. Our main focus was then the S-wave velocity structure of the area, which we determined by the Neighborhood Algorithm inversion method at each station, where data were sub-divided into back-azimuthal bundles based on similar Ps delay times. The 1D, nonlinear inversions provided the depth of the discontinuities, shear-wave velocities and Vp/Vs ratios of each layer per bundle, and we calculated uncertainty values for each of these parameters. We then developed a 3D interpolation method based on natural neighbor interpolation to obtain the 3D crustal structure from the local inversion results. We present the sedimentary thickness map, the first Conrad depth map and an improved, detailed Moho map, as well as the first upper and lower crustal thickness maps obtained from receiver function analysis. The velocity jump across the Conrad discontinuity is estimated at less than 0.2 km/s over most of the investigated area. We also compare the new Moho map from our approach to simple grid search results and prior knowledge from other techniques. Our Moho depth map presents local variations in the investigated area: the crust-mantle boundary is at 20–26 km beneath the sedimentary basins, while it is situated deeper below the Apuseni Mountains, Transdanubian and North Hungarian Ranges (28–33 km), and it is the deepest beneath the Eastern Alps and the Southern Carpathians (40–45 km). These values reflect well the Neogene evolution of the region, such as crustal thinning of the Pannonian Basin and orogenic thickening in the neighboring mountain belts.

- Abstract
The region around the town Albstadt, SW Germany, was struck by four damaging earthquakes with magnitudes greater than 5 during the last century. These earthquakes occurred along the Albstadt Shear Zone (ASZ), which is characterized by more or less continuous microseismicity. As there are no visible surface ruptures that may be connected to the fault zone, we study its characteristics by its seismicity distribution and faulting pattern. We use the earthquake data of the state earthquake service of Baden-Württemberg from 2011 to 2018 and complement it with additional phase picks beginning in 2016 at the AlpArray and StressTransfer seismic networks in the vicinity of the ASZ. This extended data set is used to determine new minimum 1-D seismic vp and vs velocity models and corresponding station delay times for earthquake relocation. Fault plane solutions are determined for selected events, and the principal stress directions are derived. The minimum 1-D seismic velocity models have a simple and stable layering with increasing velocity with depth in the upper crust. The corresponding station delay times can be explained well by the lateral depth variation of the crystalline basement. The relocated events align about north–south with most of the seismic activity between the towns of Tübingen and Albstadt, east of the 9∘ E meridian. The events can be separated into several subclusters that indicate a segmentation of the ASZ. The majority of the 25 determined fault plane solutions feature an NNE–SSW strike but NNW–SSE-striking fault planes are also observed. The main fault plane associated with the ASZ dips steeply, and the rake indicates mainly sinistral strike-slip, but we also find minor components of normal and reverse faulting. The determined direction of the maximum horizontal stress of 140–149∘ is in good agreement with prior studies. Down to ca. 7–8 km depth SHmax is bigger than SV; below this depth, SV is the main stress component. The direction of SHmax indicates that the stress field in the area of the ASZ is mainly generated by the regional plate driving forces and the Alpine topography. more...

The recent development of ambient noise tomography, in combination with the increasing number of permanent seismic stations and dense networks of temporary stations operated during passive seismic experiments, provides a unique opportunity to build the first high-resolution 3-D shear wave velocity (vS) model of the entire crust of the Bohemian Massif (BM). This paper provides a regional-scale model of velocity distribution in the BM crust. The velocity model with a cell size of 22 km is built using a conventional two-step inversion approach from Rayleigh wave group velocity dispersion curves measured at more than 400 stations. The shear velocities within the upper crust of the BM are ∼0.2 km s−1 higher than those in its surroundings. The highest crustal velocities appear in its southern part, the Moldanubian unit. The Cadomian part of the region has a thinner crust, whereas the crust assembled, or tectonically transformed in the Variscan period, is thicker. The sharp Moho discontinuity preserves traces of its dynamic development expressed in remnants of Variscan subductions imprinted in bands of crustal thickening. A significant feature of the presented model is the velocity-drop interface (VDI) modelled in the lower part of the crust. We explain this feature by the anisotropic fabric of the lower crust, which is characterised as vertical transverse isotropy with the low velocity being the symmetry axis. The VDI is often interrupted around the boundaries of the crustal units, usually above locally increased velocities in the lowermost crust. Due to the north-west–south-east shortening of the crust and the late-Variscan strike-slip movements along the north-east–south-west oriented sutures preserved in the BM lithosphere, the anisotropic fabric of the lower crust was partly or fully erased along the boundaries of original microplates. These weakened zones accompanied by a velocity increase above the Moho (which indicate an emplacement of mantle rocks into the lower crust) can represent channels through which portions of subducted and later molten rocks have percolated upwards providing magma to subsequently form granitoid plutons. more...

We compiled a dataset of continuous recordings from the temporary and permanent seismic networks to compute the high-resolution 3D S-wave velocity model of the Southeastern Alps, the western part of the external Dinarides, and the Friuli and Venetian plains through ambient noise tomography. Part of the dataset is recorded by the SWATH-D temporary network and permanent networks in Italy, Austria, Slovenia and Croatia between October 2017 and July 2018. We computed 4050 vertical component cross-correlations to obtain the empirical Rayleigh wave Green’s functions. The dataset is complemented by adopting 1804 high-quality correlograms from other studies. The fast-marching method for 2D surface wave tomography is applied to the phase velocity dispersion curves in the 2–30 s period band. The resulting local dispersion curves are inverted for 1D S-wave velocity profiles using the non-perturbational and perturbational inversion methods. We assembled the 1D S-wave velocity profiles into a pseudo-3D S-wave velocity model from the surface down to 60 km depth. A range of iso-velocities, representing the crystalline basement depth and the crustal thickness, are determined. We found the average depth over the 2.8–3.0 and 4.1–4.3 km/s iso-velocity ranges to be reasonable representations of the crystalline basement and Moho depths, respectively. The basement depth map shows that the shallower crystalline basement beneath the Schio-Vicenza fault highlights the boundary between the deeper Venetian and Friuli plains to the east and the Po-plain to the west. The estimated Moho depth map displays a thickened crust along the boundary between the Friuli plain and the external Dinarides. It also reveals a N-S narrow corridor of crustal thinning to the east of the junction of Giudicarie and Periadriatic lines, which was not reported by other seismic imaging studies. This corridor of shallower Moho is located beneath the surface outcrop of the Permian magmatic rocks and seems to be connected to the continuation of the Permian magmatism to the deep-seated crust. We compared the shallow crustal velocities and the hypocentral location of the earthquakes in the Southern foothills of the Alps. It revealed that the seismicity mainly occurs in the S-wave velocity range between ∼3.1 and ∼3.6 km/s. more...

SUMMARYProbing seismic anisotropy of the lithosphere provides valuable clues on the fabric of rocks. We present a 3-D probabilistic model of shear wave velocity and radial anisotropy of the crust and uppermost mantle of Europe, focusing on the mountain belts of the Alps and Apennines. The model is built from Love and Rayleigh dispersion curves in the period range 5–149 s. Data are extracted from seismic ambient noise recorded at 1521 broad-band stations, including the AlpArray network. The dispersion curves are first combined in a linearized least squares inversion to obtain 2-D maps of group velocity at each period. Love and Rayleigh maps are then jointly inverted at depth for shear wave velocity and radial anisotropy using a Bayesian Monte Carlo scheme that accounts for the trade-off between radial anisotropy and horizontal layering. The isotropic part of our model is consistent with previous studies. However, our anisotropy maps differ from previous large scale studies that suggested the presence of significant radial anisotropy everywhere in the European crust and shallow upper mantle. We observe instead that radial anisotropy is mostly localized beneath the Apennines while most of the remaining European crust and shallow upper mantle is isotropic. We attribute this difference to trade-offs between radial anisotropy and thin (hectometric) layering in previous studies based on least-squares inversions and long period data (>30 s). In contrast, our approach involves a massive data set of short period measurements and a Bayesian inversion that accounts for thin layering. The positive radial anisotropy (VSH > VSV) observed in the lower crust of the Apennines cannot result from thin layering. We rather attribute it to ductile horizontal flow in response to the recent and present-day extension in the region. more...

SUMMARYTo constrain seismic anisotropy under and around the Alps in Europe, we study SKS shear wave splitting from the region densely covered by the AlpArray seismic network. We apply a technique based on measuring the splitting intensity, constraining well both the fast orientation and the splitting delay. Four years of teleseismic earthquake data were processed, from 723 temporary and permanent broad-band stations of the AlpArray deployment including ocean-bottom seismometers, providing a spatial coverage that is unprecedented. The technique is applied automatically (without human intervention), and it thus provides a reproducible image of anisotropic structure in and around the Alpine region. As in earlier studies, we observe a coherent rotation of fast axes in the western part of the Alpine chain, and a region of homogeneous fast orientation in the Central Alps. The spatial variation of splitting delay times is particularly interesting though. On one hand, there is a clear positive correlation with Alpine topography, suggesting that part of the seismic anisotropy (deformation) is caused by the Alpine orogeny. On the other hand, anisotropic strength around the mountain chain shows a distinct contrast between the Western and Eastern Alps. This difference is best explained by the more active mantle flow around the Western Alps. The new observational constraints, especially the splitting delay, provide new information on Alpine geodynamics. more...

- Abstract
Despite their geographical and cultural proximity, Germany, Austria, and Switzerland can teach very different lessons on how to handle the COVID-19 pandemic. Timing and severity of outbreaks were fairly similar in Germany and Austria (see Figures 17.1 through 17.3), whereas Switzerland faced a higher infection rate at the peak of the crisis (although far from rates in France or Italy). Response measures eventually taken by the three countries were not too different, either, but how decisions were made and subsequently communicated to the public varied considerably. In all three countries, containment measures were met by a high level of adherence within the population, as mobility indices illustrate (see Figures 17.1 through 17.3). As a result, the three countries fared well in reducing transmission rates and never came close to reaching capacity limits in their health systems. This chapter aims to examine the outbreak responses of the three countries and give insight into the dynamics and rationales behind these responses. more...

- Abstract
In this study, we analyzed a large seismological dataset from temporary and permanent networks in the southern and eastern Alps to establish high-precision hypocenters and 1-D VP and VP/VS models. The waveform data of a subset of local earthquakes with magnitudes in the range of 1–4.2 ML were recorded by the dense, temporary SWATH-D network and selected stations of the AlpArray network between September 2017 and the end of 2018. The first arrival times of P and S waves of earthquakes are determined by a semi-automatic procedure. We applied a Markov chain Monte Carlo inversion method to simultaneously calculate robust hypocenters, a 1-D velocity model, and station corrections without prior assumptions, such as initial velocity models or earthquake locations. A further advantage of this method is the derivation of the model parameter uncertainties and noise levels of the data. The precision estimates of the localization procedure is checked by inverting a synthetic travel time dataset from a complex 3-D velocity model and by using the real stations and earthquakes geometry. The location accuracy is further investigated by a quarry blast test. The average uncertainties of the locations of the earthquakes are below 500 m in their epicenter and ∼ 1.7 km in depth. The earthquake distribution reveals seismicity in the upper crust (0–20 km), which is characterized by pronounced clusters along the Alpine frontal thrust, e.g., the Friuli-Venetia (FV) region, the Giudicarie–Lessini (GL) and Schio-Vicenza domains, the Austroalpine nappes, and the Inntal area. Some seismicity also occurs along the Periadriatic Fault. The general pattern of seismicity reflects head-on convergence of the Adriatic indenter with the Alpine orogenic crust. The seismicity in the FV and GL regions is deeper than the modeled frontal thrusts, which we interpret as indication for southward propagation of the southern Alpine deformation front (blind thrusts). more...

- Abstract
Highlights • Rayleigh-wave phase velocity in the wider Dinarides region using the two-station method. • Uppermost mantle shear-wave velocity model of the Dinarides-Adriatic Sea region. • Velocity model reveals a robust high-velocity anomaly present under the whole Dinarides. • High-velocity anomaly reaches depth of 160 km in the northern Dinarides to more than 200 km under southern Dinarides. • New structural model incorporating delamination as one of the processes controlling the continental collision in the Dinarides. The interaction between the Adriatic microplate (Adria) and Eurasia is the main driving factor in the central Mediterranean tectonics. Their interplay has shaped the geodynamics of the whole region and formed several mountain belts including Alps, Dinarides and Apennines. Among these, Dinarides are the least investigated and little is known about the underlying geodynamic processes. There are numerous open questions about the current state of interaction between Adria and Eurasia under the Dinaric domain. One of the most interesting is the nature of lithospheric underthrusting of Adriatic plate, e.g. length of the slab or varying slab disposition along the orogen. Previous investigations have found a low-velocity zone in the uppermost mantle under the northern-central Dinarides which was interpreted as a slab gap. Conversely, several newer studies have indicated the presence of the continuous slab under the Dinarides with no trace of the low velocity zone. Thus, to investigate the Dinaric mantle structure further, we use regional-to-teleseismic surface-wave records from 98 seismic stations in the wider Dinarides region to create a 3D shear-wave velocity model. More precisely, a two-station method is used to extract Rayleigh-wave phase velocity while tomography and 1D inversion of the phase velocity are employed to map the depth dependent shear-wave velocity. Resulting velocity model reveals a robust high-velocity anomaly present under the whole Dinar more...

- Abstract
Constraining the architecture of complex 3D volcanic plumbing systems within active rifts, and their impact on rift processes, is critical for examining the interplay between faulting, magmatism and magmatic fluids in developing rift segments. The Natron basin of the East African Rift System provides an ideal location to study these processes, owing to its recent magmatic-tectonic activity and ongoing active carbonatite volcanism at Oldoinyo Lengai. Here, we report seismicity and fault plane solutions from a 10-month temporary seismic network spanning Oldoinyo Lengai, Naibor Soito volcanic field and Gelai volcano. We locate 6827 earthquakes with ML -0.85 to 3.6, which are related to previous and ongoing magmatic and volcanic activity in the region, as well as regional tectonic extension. We observe seismicity down to ~17 km depth north and south of Oldoinyo Lengai and shallow seismicity (3 - 10 km) beneath Gelai, including two swarms. The deepest seismicity (~down to 20 km) occurs above a previously imaged magma body below Naibor Soito. These seismicity patterns reveal a detailed image of a complex volcanic plumbing system, supporting potential lateral and vertical connections between shallow- and deep-seated magmas, where fluid and melt transport to the surface is facilitated by intrusion of dikes and sills. Focal mechanisms vary spatially. T-axis trends reveal dominantly WNW-ESE extension near Gelai, while strike-slip mechanisms and a radial trend in P-axes are observed in the vicinity of Oldoinyo Lengai. These data support local variations in the state of stress, resulting from a combination of volcanic edifice loading and magma-driven stress changes imposed on a regional extensional stress field. Our results indicate that the southern Natron basin is a segmented rift system, in which fluids preferentially percolate vertically and laterally in a region where strain transfers from a border fault to a developing magmatic rift segment. more...

- Abstract
Highlights • Full automatized analysis of teleseismic XKS shear wave splitting. • Rapid analysis of large seismological data sets. • Automated window selection and quality classification. • Application to the USArray Transportable Array including expansion to Alaska. • Improved statistical evidence and objectivity of derived effective splitting. Abstract Recent technological advances have led to community wide use of large-scale seismic experiments which produce seismic data on previously impossible scales. Standard processing procedures thus require automatization to facilitate a fast and objective analysis of the data. Among these, XKS-splitting is an important tool to derive first insights into the Earth's deformation regimes at depth by studying seismic anisotropy. Most often, shear-wave splitting is interpreted to represent crystallographic preferred orientation (CPO) of mantle minerals like olivine as dominating feature and can thus be used as a proxy of mantle flow processes. Here, we introduce an addition to the MATLAB®-based SplitRacer tool box (Reiss and Rümpker 2017) which automatizes the entire XKS-splitting procedure. This is achieved by the automatization of 1) choosing a time window based on spectral analyses and 2) categorization of results based on three different XKS-splitting methods (energy minimization, rotation correlation and splitting intensity). This provides effective and objective results for splitting as well as null-measurement results. This extension allows to use SplitRacer without a graphical interface and introduces a bootstrapping statistics as error estimate of the single layer joint splitting method. The procedures are designed to allow a fast and more objective analysis of a vast amount of data, as produced by recent seismic deployments (e.g. USArray, AlpArray). We test this automatization by applying the analysis to the USArray data set, which has approximately 1900 stations with between two to fifteen years of data. We can repr more...

In this study, we analyzed a large seismological dataset from temporary and permanent networks in the southern and eastern Alps to establish high-precision hypocenters and 1-D VP and VP/VS models. The waveform data of a subset of local earthquakes with magnitudes in the range of 1–4.2 ML were recorded by the dense, temporary SWATH-D network and selected stations of the AlpArray network between September 2017 and the end of 2018. The first arrival times of P and S waves of earthquakes are determined by a semi-automatic procedure. We applied a Markov chain Monte Carlo inversion method to simultaneously calculate robust hypocenters, a 1-D velocity model, and station corrections without prior assumptions, such as initial velocity models or earthquake locations. A further advantage of this method is the derivation of the model parameter uncertainties and noise levels of the data. The precision estimates of the localization procedure is checked by inverting a synthetic travel time dataset from a complex 3-D velocity model and by using the real stations and earthquakes geometry. The location accuracy is further investigated by a quarry blast test. The average uncertainties of the locations of the earthquakes are below 500 m in their epicenter and ∼ 1.7 km in depth. The earthquake distribution reveals seismicity in the upper crust (0–20 km), which is characterized by pronounced clusters along the Alpine frontal thrust, e.g., the Friuli-Venetia (FV) region, the Giudicarie–Lessini (GL) and Schio-Vicenza domains, the Austroalpine nappes, and the Inntal area. Some seismicity also occurs along the Periadriatic Fault. The general pattern of seismicity reflects head-on convergence of the Adriatic indenter with the Alpine orogenic crust. The seismicity in the FV and GL regions is deeper than the modeled frontal thrusts, which we interpret as indication for southward propagation of the southern Alpine deformation front (blind thrusts). more...

- Abstract
Aufgabe des innerhalb von wenigen Tagen erstellten Kurzgutachtens war es, Evidenz zu den Einflussfaktoren auf Hospitalisierungs-und Sterberaten bei Infektion mit SARS-CoV-2zu generieren, insbesondere in Hinblick auf die starken Unterschiede zwischen Österreich bzw.Wien einerseits und Ländern wie China, Italien und Spanien andererseits. Die Studie zeigt, dass es wenige Faktoren gibt, die Wien in eine dauerhaftbegünstigte Situation versetzen, da die vulnerable Bevölkerung nach wie vor suszeptibel ist. Eine Lockerung der Eindämmungsmaßnahmen müsste mit einer alternativen Strategie einhergehen, die auf syndromic surveillance, weitreichendes contact tracing, Infektionsschutz-und Hygienemaßnahmen und besonderen Schutz der vulnerablen Bevölkerungsgruppen setzt more...

- Abstract
Zu den wirtschaftlichen Auswirkungen des Ausbruchs von SARS-CoV-2 können zum jetzigen Zeitpunkt lediglich Schätzungen vorgenommen werden. Wir präsentieren im vorliegenden Policy Brief eine solche aktualisierte Schätzung für die österreichische Volkswirtschaft. War zunächst primär die Wirtschaft in China, so sind mittlerweile auch andere Länder, insbesondere Italien, direkt betroffen. In unseren Berechnungen nehmen wir einen Einbruch des chinesischen Wirtschaftswachstums auf Basis der verfügbaren Quellen für das Jahr 2020 um einen Prozentpunkt an. Auch für Italien wird eine Verminderung um einen Prozentpunkt angenommen, für Deutschland und Frankreich um 0,4 bzw. 0,3 Prozentpunkte, für den Rest der Welt um 0,2 Prozentpunkte. Weiters beziehen wir auch Rückgänge im Konsum betroffener Länder sowie die voraussichtlichen Rückgänge im Tourismus in Österreich in unsere Berechnungen mit ein. Wir kommen zu dem Ergebnis, dass der Wertschöpfungsverlust für Österreich im Jahr 2020 nach aktuellem Informationsstand in Summe etwa EUR 1,3 Mrd. betragen wird, vorwiegend verursacht durch Einbußen bei den Exporten. Der Verlust von Steuer- und Abgabeneinnahmen lässt sich mit rund EUR 480 Mio. beziffern. Aufgrund der Unsicherheit bzgl. der weiteren Verbreitung des Virus müssen solche Schätzungen jedoch immer wieder an neue Gegebenheiten angepasst werden. Noch nicht einbezogen werden konnten auch die Maßnahmen der österreichischen Bundesregierung, die heute, 10.03.2020, getroffen wurden. Daher sind die ausgewiesenen Effekte mit großer Wahrscheinlichkeit an der Untergrenze der möglichen Effekte angesiedelt. more...
