Seismic risk assesment for transboundary area of Romania and Republic of Moldova Ungheni - Ungheni-Prut

Abstract

Present paper objective is to assess the seismic hazard and seismic risk and provide an analyses of earthquake scenario for the transboundary area of Ungheni town in Republic of Moldova and Ungheni-Prut in Romania. For the present study as design seismic action (earthquake scenario) was selected the Vrancea earthquake with 475 years return period and magnitude Mw = 7.9. At first it was analyzed specified earthquake scenario using special macro seismic attenuation equation. This allowed the obtaining of probable distribution of the intensity in the study area. The estimation of seismic risk analyses and vulnerability of buildings in the study area was made based on statistical data and field evaluation in terms of MSK-64, especially for urban area of Ungheni, and transboundary villages.
