Abstract
Summary
Intensity is a basic parameter for assessment historical seismicity - realized until the instrumental period. The relation between intensity and seismic moment magnitude allows the creation of a homogeneous catalog. The homogeneous catalog provides compatibility of the input seismological data and allow reliable estimation of the energy distribution of earthquakes - an important stage in seismological research and essential for seismic hazard assessment. In this study are analyzed 92 earthquakes with magnitude above 4.0 (M>4.0), which occurred in space window 37.0° – 45.0° N; 21.0° – 30.0° E, during the time period 1912 – 2018 and the coefficients of the linear regression MW=MW(I0/Imax) are evaluated.
