【Abstract】 Based on the reasonable selection of locating model, locating method and seismic phases, using seismological data from more reasonably distributed seismic network, precise locating of the Changshu Taicang earthquake of M5 1 on 10 Feb 1990 has been made and more precise and more reasonable parameters of the earthquake have been obtained The result of the reexamination of the focal mechanism solution of the earthquake has indicated that the earlier focal mechanism result needs no modification更多还原
