Abstract

Based on digital seismic waveform data from Hebei seismic network,source spectrum parameters of 62 small and moderate earthquakes form December 2008 to April 2010 are derived,the seismic moment M0 and moment magnitude Mw of the earthquakes are calculated.The relational expression between body wave magnitude ML and moment magnitude Mw of local earthquake are obtained using orthogonal regression method.
