2004年12月26日印尼8.7级强震后江苏地区同震效应分析

在2004年12月26日印尼苏门答腊北部发生8.7级强烈地震后,对江苏省地震前兆观测资料进行了及时的清理和分析,发现凡是能监测地下应力活动的前兆观测手段,如应变、地倾斜、水温和水位,在这次特大地震的震后都记录到了显著的异常,且异常的表现形式各不相同,将这些异常列出并浅析之,以期对进一步深入研究这次地震对我国未来地震趋势的影响有所帮助。

Analysis of the Coseismic Effects on Jiangsu Province of the M8.7, Indonesia, Earthquake of Dec.26, 2004

After the M8.7 earthquake, which occured in the northern part of Indonesia on December 26, 2004,the precursor data of the earthquake observed in Jiangsu province is timely analysed in the paper. It is shown that those which can monitor change in stress underground, such as strain, ground tilt, water temperature and water level fluctuation, can all reflect evident abnormal phenomena in different forms after the earthquake. The analysis of the abnormal phenomena, is helpful for further researches into the influence of the great earthquake on trend in China future earthquake.
