Application of a probabilistic model to vrancea intermediate earthquakes

The seismic hazard parameters of the Vrancea seismogenic region are derived by applying a probabilistic model (the Epstein-Lomnitz model) making use of the first type of Gumbel distribution. The extreme value data are of two types: macroseismic data (1901–1933) and instrumental data (1934–1991). The output parameters (In = 8.30; = 1.67), for the set I and (In = 9.33; = 1.87) for the set II allow a more reliable estimation of the basic hazard parameters and they are discussed and compared with previous works.
