Magnitude deviation analysis of surface wave magnitude at Tazhong Seismic Station
The global MS ≥ 5.5 seismic events recorded by Tazhong Seismic Station during 2018-2021 were selected to calculate the surface wave magnitudes MS7 and MS(BB),and analyze the deviation between them and the magnitudes published by United States Geological Survey (USGS) and China Earthquake Networks Center (CENC). The results show that the correlation between the two magnitudes is higher than that of USGS and CENC,but the MS7 magnitude deviation is smaller (0.18 and 0.27),which is more informative in applications.
