Abstract

Nell'ambito di un programma di prevenzione/previsione del rischio sismico, la Regione Toscana ha finanziato la realizzazione di una rete di monitoraggio geochimico (la rete Geochimica Toscana - GNT: Geochemical Network of Tuscany) per studiare possibili relazioni tra le variazioni di chimismo nelle acque sotterranee e gli eventi sismici (Cioni et al., 2007). La GNT è operativa dalla fine del 2002 e attualmente è costituita da 6 stazioni automatiche di monitoraggio continuo installate nelle aree a maggiore pericolosità sismica della Toscana: Garfagnana, Lunigiana, Mugello, Valtiberina e comprensorio del Monte Amiata. Tutte le stazioni sono dotate di sensori per le misurazioni simultanee di 6 parametri nelle acque: temperatura, pH, potenziale redox, conducibilità elettrica e le concentrazioni di CO2 e CH4 disciolti. La stazione automatica di Bagnore è stata installata nel 2004 alle pendici del Monte Amiata (Toscana meridionale). Gli aumenti significativi nei parametri monitorati, registrati a partire dalla fine di marzo 2016 sono coerenti con un aumento dell'assorbimento di gas idrotermali (prevalentemente CO2, H2S e vapore) dal serbatoio geotermico sottostante e potrebbero essere correlati a variazioni di permeabilità connesse alle fasi preparatorie dei terremoti avvenuti nel 2016, a partire dal terremoto di Orvieto del 30 maggio di Mw = 4.1.

Abstract

The present-day velocity field has been estimated by the analysis of geodetic measurements in the northern Apennines, using the fairly dense network of GPS permanent stations now available in that zone. The first results of this investigation indicate a significantly higher mobility of the central sector of the Northern Apennines Arc (Umbria-Marche-Romagna units), with respect to the northwestern sector (Ligurides units) and the internal zone (Tuscany). This kinematics may account for the distribution of seismicity and the related strain field in the study area.

Abstract

Seismic microzonation maps usually represent local seismic hazard through amplification factors, i.e. relative values, and reference seismic hazard maps do not consider the local effects that may derive from local geological and morphological conditions. For the implementation of policies to reduce the seismic risk, authorities responsible for territorial management need realistic seismic hazard maps comparable on a national scale. Thanks to the available data on geology and seismic hazard and to the procedures indicated by the Regional and national guidelines, it is possible to produce, quickly and cost-effectively, site seismic hazard maps at any scale. The use of the HSM parameter for this mapping makes it possible to consider both the reference seismic hazard and the local effects and makes the final results comparable on a national scale; therefore, it allows a realistic classification of the seismic hazard applicable to all scales. The results of tests conducted on local and regional scales, according to national and Regional guidelines, are shown and discussed. [ABSTRACT FROM AUTHOR]

Abstract

In previous papers, we have argued that a close connection may exist between the discontinuous northward displacement of the Adria plate and the spatio-temporal distribution of major earthquakes in the periAdriatic regions [1]-[3]. In particular, five seismic sequences are tentatively recognized in the post 1400 A.D. seismic history, each characterized by a progressive migration of major shocks along the eastern (Hellenides, Dinarides), western (Apennines) and northern (Eastern Southern Alps) boundaries of Adria. In this work, we describe an attempt at gaining insights into the short-term evolution of the strain field that underlies the migration of seismicity in the Apennine belt. The results of this study suggest that seismicity in the study area is mainly conditioned by the fact that the outer (Adriatic) sector of the Apennine belt, driven by the Adria plate, is moving faster than the inner (Tyrrhenian) belt. This kinematics is consistent with the observed Pleistocene deformation pattern and the velocity field inferred by GPS data. The spatio-temporal distribution of major shocks during the last still ongoing seismic sequence (post 1930) suggests that at present the probability of next major shocks is highest in the Northern Apennines. Within this area, we suggest that seismic hazard is higher in the zones located around the outer sector of the Romagna-Marche-Umbria units (RMU), since that wedge is undergoing an accelerated relative motion with respect to the inner Apennine belt. This hypothesis may also account for the pattern of background seismicity in the Northern Apennines. This last activity might indicate that the Upper Tiber Valley fault system is the most resisted boundary sector of the RMU mobile wedge, implying an higher probability of major earthquakes.
