摘要
本文收集、整理了2004年12月26日印尼苏门答腊西北近海8.7级地震及2005年印尼8.5级和巴基斯坦7.8级地震时福建省地下流体数字化监测台网观测到的震时和震后效应。结果表明以永安—晋江断裂为界线,北边多数观测井表现为水位上升,南边多数观测井为下降。初步分析认为,这种现象可能与现代构造应力场有关。
Based on collecting and processing the data of co-seismic and post-seismic effect of Sumatra M8.7 Earthquake on Dec. 26, 2005, Indonesia M8.5 Earthquake and Pakistan M7.8 Earthquake in 2005, observed by Digital Underground Water Monitoring Network in Fujian Province, the results show that the Yongan-Jinjiang Fault is a margin, which divides two different regions of ground water level changes, it increases in the region lying north of the fault, while decreases in the south of the fault during and after the earthquakes mentioned above. By analyzing, this phenomenon may be related to the variation of modern tectonic stress field caused by the large distant earthquakes.
