Water flow from an artesian well stopped on December 17, 2007 but recovered when the Wenchuan Ms 8.0 earthquake occurred on May 12, 2008. This well is located 90 km south of the epicenter in an extensional tectonic setting, where similar changes of water level and resistivity were observed at two other nearby sites. Our investigation suggests that this phenomenon was not caused by environmental disturbances, such as drought or borehole-drilling activity, but might be a precursor to the earthquake.

作者： che yongtai chen Junhua Zhang Lifen Yu Jinzi Liu chenglong Zhang Weihua Institute of Geology China Earthquake Administration Beijing 100029 China Earthquake Administration of Hubei Province Wuhan 430071 China

In this paper,based on the collected data and earthquake field investigation,characteristics of the MS4.1 Hujiaping earthquake of November 22,2008 at Guizhou town in Zigui county,Hubei Province and the geological and hydrogeological conditions and seismicity background of the area are analyzed,and the earthquake disaster is presented. Some scientific issues relating to earthquake precursors and the cause of the earthquake is discussed. The authors consider that the earthquake is a tectonic type reservoir-induced earthquake,occurring along the Xiannvshan fault under the joint action of reservoir water loading and water infiltration,and that there were certain suspected anomalies appearing in the gravity field before the earthquake. The cause of the earthquake may also be related to the effect of the Wenchuan earthquake on the local stress field.

High-value subsurface fluid anomalies appeared in the northern part of North China region for more than two years before the Zhangbei-Shangyi earthquake. Some of the anomalies have appeared alternately and were correlated with moderate and moderately strong earthquakes in the region during the last year (1997). Typical short-term subsurface fluid anomalies have appeared in the area at 100 km ~ 200 km distance from the epicenter for two months before an earthquake. Tracing these anomalies during the last two years and repeatedly improving the knowledge of seismic regime, we have more successfully performed short-term and imminent earthquake prediction at half a month before its occurrence.
