南昌井水位对远震的同震响应分析

Analysis on Coseismic Response of Nanchang Well Water Levels to Teleseismic

通过对2001—2008年间139次震例数字化资料的总结,定性分析了南昌井水位资料对强远震的响应情况,并采用二阶回归方法对模型进行优化和定量分析。研究认为:南昌井水位资料对强远震响应较好,同震响应幅度与震级、震中距综合相关,响应距离随震级增加而增加,但在各震级档中均存在距离上限。

The coseismic response characteristics of the Nanchang well water level to teleseismic has been analysis by summarizing digital data of 139 earthquakes from 2001 to 2008. The two order regression method has also been used to optimize and analyze the model. The results show that the Nanchang well water level has better response to strong teleseismie and the amplitude of the coseismic response is closely related to earthquake magnitude and epieentral distance. The response distance increases with the increase of magnitude, but there is an upper limit of epicentral distance for each magnitude level.
