Abstract: This paper represents the Romanian contribution in the frame of the European Co-operation "COST ACTION 625" and it is centered on an electromagnetic methodology for the natural hazard assessment due to both the seismic events and associated active faults which are considered to be sources of the most significant landslides in the Subcarpathian area (Romania). This methodology was established according to the geotectonic features of the seismic-active Vrancea zone and Provita de Sus landslide area. Subsequently, a specific approach regarding the electromagnetic precursory parameters, selected according to the temporal invariability criterion for a 2D geoelectric structure in non-seismic condition, taking into consideration their daily mean distribution versus intermediate depth seismic events recorded simultaneously, was elaborated. A similar electromagnetic technique conveying to additional parameters and models concerning the evolution in time of the landslide phenomena was also imposed, so that a disaster forecasting become possible. |
