Abstract

Seismograms and accelerograms from 77 earthquakes in 1982 to 1984 near the northwest end of the Red River fault in western Yunnan Province, Peoples Republic of China, have been used to calculate seismic moment, M//O, and local magnitude, M//L, using techniques established in California. For 1 1/2 APP 1STH M//L APP 1STH 3 1/2, log M//O equals 16. 97 plus (1. 17 plus or minus 0. 05)M//L, consistent with the log M//O minus M//L relation appropriate for central California. A comparison of these M//L values and the coda duration magnitudes M and S-wave amplitude magnitudes M assigned by the Seismological Bureau of Yunnan Province suggests that M and M values are generally larger than the M//L values.
