Relationships between macroseismic intensity and peak ground acceleration and velocity for the Vrancea (Romania) subcrustal earthquakes

The goal of this paper is to develop a new empirical relationship between observed macroseismic intensity and strong ground motion parameters such as peak acceleration (PGA) velocity (PGV) for the Vrancea subcrustal earthquakes. recent earthquakes provide valuable data examine these relationships seismogenic region. This region one most active seismic zones in Europe it well-known We correlation ground-motion records intensities major moderate with Mw ≥ 5.4 epicentral range VI IX MSK degrees that occurred zone period 1977-2009. maximum obtained published by various authors have shown do not always show one-to-one correspondence, errors associated estimation from PGA/PGV are sometimes +/-2 degree. In present study, relation will be given both mathematical equation, but also corresponding intervals. Because spreading related approximations, necessary systematically monitor only all other parameters. might used rapid assessment shaking severity potential damages areas affected
