Deviation Analysis and Correction for Surface Wave Magnitude at Danjiang Seismic Station
Abstract Based on the 572 surface wave magnitudes measured by Danjiang seismic station in 2018, compared with the surface wave magnitudes of the seismic observation report of CENC, we analyze the relationship between the magnitude deviation and magnitude, epicentral distance, and epicenter azimuth. The results show that the MS magnitude of Danjiang seismic station is 0.13 lower than that of CENC, and the magnitude deviation decreases gradually with the increase of magnitude and epicentral distance. The magnitude deviation is not significantly affected by epicenter azimuth.
Key words :
surface wave magnitude
magnitude deviation
epicenter azimuth
