Study on the magnitude deviation determined by the digital seismometer in Seismic Standard Station of Chengdu
HU Jun-ming · Earthquake Research in Sichuan · 2012
Firstly the reliability of the seismic magnitude determined by the Seismic Standard Station of Chengdu and the deviation from the one of China Seismic Network are discussed.Then the corrective value is put forward.In the practice the data for determining the seismic magnitude should be the travel time of surface wave.
