2008年5月12日四川省汶川MS8.0地震在全国引起了大范围的同震及震后效应,能否将这些信息应用于地震预报,为震情判断提供依据?本文以福建流体台网井水位为例,将同震效应时空展布特征结合福建区域同期发生的地震事件进行分析,认为震后阶跃上升变化的水井水位可能包含有区域应力场信息,水位阶跃上升集中区可能是区域应力相对集中区,对未来该区域发生较显著的地震具有空间上的指示意义,可能就是未来的发震危险区.
May 12, 2008 Wenchuan MS8.0 earthquake in Sichuan Province caused a wide range of coseismic and post-earthquake effects across the country. Can these information be used in earthquake prediction to provide basis for the earthquake assessment? In this paper, Fujian Fluid Network Taking the water level in the well as an example, the temporal and spatial distribution of coseismic effect is analyzed in combination with the seismic events occurring in the same area of Fujian Province. It is concluded that the well water level fluctuating upward after the earthquake may contain regional stress field information. The relative concentrated area of regional stress has the spatial indication to the more significant earthquakes in the future and may be the future earthquake-prone danger area.
