Objective Problems to be solvedThe aim of the project is to contribute to improve observational, experimental and theoretical methodologies for seismic hazard assessment. The work will focus in the highly seismic Aigion area, Gulf of Corinth, Greece. Tectonic studies with geomorphology, trenching, and coring in quaternary sediments, associated with dating, will provide information of long and mid term deformation and rupture sequences of the major faults. Continuous GPS will bring space and time variability of the strain field. Borehole and surface high dynamic accelerometers in soft soil sites will allow the study of non-linear effects. Continuous geophysical (strain, tilt, pore water pressure,) and geochemical monitoring will detect crustal transients, to be analysed together with seismicity. Scientific objectives and approach The tectonic studies consist of a detailed geomorphologic survey of the area, trenching on the two major fault scarps and dating of the rupture episodes, drilling at shallow depth (tens of meters) for dating of quaternary sediments. Long-term subsistence and uplift, as well as time series of rupture, will be analysed. The source seismological studies consist of deploying broadband surface accelerometers on rock sites, installing an array of shallow borehole velocimeters (100-150 m), and installing deep borehole high dynamic accelerometers (400 m and 100 m). For the engineering seismology and earthquake engineering studies, shallow boreholes drilled in soft soils will be equipped with high dynamic accelerometers. In site and laboratory dynamic tests will be performed to define soil profile with a detailed description of the dynamic soil properties. Finally, a buried structure will be instrumented with a few accelerometers. Experimental and theoretical analysis of non-linear behaviour of soils will be achieved. The data mostly telemeters via phone line, will be processed and stored in several databases. It will be available on request after validation and first publications. Catalogues of seismicity will be available. Effects of surface geology and of soft behaviour will be quantified. Models of crustal processes and fault mechanics, sequences of paleoearthquakes, as well as long and short-term slip on the two major faults will be published.Expected impactsThe project will allow defining better methodologies in the whole chain of the seismic hazard assessment process. The resulting increase of expertise in Europe will allow better advising and collaboration with the end-users (Electricité de France, International Agency of Nuclear Energy and Nuclear Waste) for practical applications. It will in particular provide reliable design values for the Eurocode 8, based on strong data and taking into account non-linear behaviour of soils.
