Abstract

Geospatial information forms the basis for comprehensive seismic risk assessments and better-informed mitigation planning, disaster assessment and response prioritization. Mainly due to the subcrustal earthquakes located at the sharp bend of the Southeast Carpathians, Vrancea zone in Romania is considered one of the most seismically active area in Europe, having a relatively high potential of seismic hazard, being placed at conjunction of four tectonic blocks which lie on the edge of the Eurasian plate. Integrated in situ monitoring seismological, geologic, geophysics, satellite (IKONOS; LANDSAT TM and ETM, SAR-ERS 1/2, ASTER) and GPS data provide a better monitoring of different geophysical-geochemical parameters and long-term deformation in relation with earthquake activity.Multispectral and multitemporal satellite images over a period 1975-2007 have been analyzed for recognizing the continuity and regional relationships of active faults as well as for geologic and seismic hazard mapping. GPS Romanian network stations data revealed a displacement of about 5 or 6 millimeters per year in horizontal direction relative motion, and a few millimeters per year in vertical direction. As Vrancea area has a significant regional tectonic activity, the joint analysis of geospatial and in-situ geophysical information is revealing new insights in the field of hazard assessment.
