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., Dumitru Stanica and Maria Stanica., and Obsahuje bibliografii
The Betic Cordillera, located at the westernmost end of the Mediterranean alpine belt, is deformed by overprinted folds and faults that produced the present-day relief since the Tortonian. In the frame of the COST 625 action, four sectors have been studied in the central part of the cordillera. In the Granad a Depression, the large NW-SE Padul normal fault deforms the SW periclinal end of the Sierra Nevada antiform. MT surveys in dicate the continuity in depth of high and low angle normal seismogenic faults and the presence of act ive detachment faults. In Tabernas regi on a good example of interaction between a N W-SE propagating normal fault, E-W strike-slip faults and the fold system is studied. In the Sierra Tejeda-Zafarraya and in the Balanegra-Sierra de Gádor areas, two new GPS networks ha ve been installed to determine the interaction and the development of large antiformal struct ures and normal faults with E-W and NW-SE orientations. However, taking into account the low tectonic activity of the studi ed region, a period of more than 5 year could be needed to determine with enough accuracy the development rate of the structures., Jesús Galindo-Zaldívar, Antonio Gil, Carlos Sanz de Galdeano, Stefan Shanov and Dumitru Stanica., and Obsahuje bibliografické odkazy
