摘要
本文通过2011年日本本州海域9.0级地震、2008年四川汶川8.0级地震和2008年6月14日日本本州东海岸近海7.0级地震前后山东莒县井水位、水温同震响应的资料变化对比分析,对区域应力进行探讨,认为日本本州海域9.0级地震的发生,是对莒县井及周边区域应力的卸载。2011年日本本州海域9.0级地震,可能对山东及周边地区近期震情起到一定的缓解作用。
This paper comparatively analyzed the water level, water temperature＇s co-seismic response and regional stress of the Ju County well before and after the three earthquakes, which are the Japanese 9.0 magnitude earthquake at Honshu sea area in 2011, Sichuan Wenehuan 8.0 magnitude earthquake in 2008, and Japanese 7.0 magnitude earthquake on June 14th, 2008 around Honshu east coast offshore. It can be concluded that the Japanese 9.0 earthquake was a kind of unloading of the regional stress of Ju County well and its surrounding area. And it may make a alleviating affect to the recent seismic situation in Shandong Province and it surrounding area.
