Paper Abstract

As one of the most seismically active area in Europe, Vrancea region in Romania presents a relatively high potential of seismic hazard mainly due to the subcrustal earthquakes located at the sharp bend of the Southeast Carpathians. Is assumed to be placed at conjunction of four tectonic blocks which lie on the edge of the Eurasian plate. Seismic hazard maps have been produced on the basis of the regional geomorphologic maps which combines information on rock types, soil types and slopes for seismically active areas. Specific stages of disaster management programs are pre-disaster planning and preparedness, forecast and warning, emergency response and rehabilitation. Spatial technologies offer a source of complementary information for ground-based sources. Fusing satellite Landsat :MSS,TM and ETM;MODIS; SAR; ASTER) data, GPS and ground measurements, greatly improved the interpretability of the images and subsequent more accurate terrain features and lineament analysis of geologic structures in Vrancea region. Based on Global Position System (GPS) monitoring data were detected relative ground motions of the tectonic blocks both in horizontal direction ( relative motion of 5- 6 millimeters/year), as well as in vertical direction(of a few millimeters/ year). Digital Elevation Models (DEM) generation from ASTER data are highly correlated with ground topography from GPS measurements in the test area. Satellite remote sensing data used provided useful information for lithological and geological lineaments mapping as well as for land geodynamic measurements of strain locating stricken and monitoring of seismic hazard.
