摘要：

Equations that could estimate the local magnitude of historical earthquakes, being difficult to calculate, in SinoKorea craton was obtained using instrumental earthquake data for 22 Korean and 46 northeastern Chinese events. The obtained equations from intensity I-0 is M-L = 1.7+0.57 x I-0. The equation from felt area FA for the Korean Peninsula is M-L = 4.29-1.34x log(FA)+0.28 x log(2)(FA). When the information on earthquake damage, effects, and felt area is all recorded at the same time, the former equation of intensity is more feasible than that of felt area due to uncertainty in earthquake felt area.
