The Dynamic Anomaly Feature Of Underground Water Level Caused By Earthquake In Panjin And Its Mechanism

Observation of the deep well level in Panjin was from the1970’s-1980’s in the lastcentury. So far a great deal of observational data was accumulated. Before the Xiuyan5.4earthquake on November29，1999and exceed Ms7.0earthquake between1993and1995far from Panjin, there was a group of former exception information. Because thesedeep wells are in the Liao He oil production areas, the water level changes wereinfluenced by the exploitation in oil field. The author researched the geology conditionhydrology condition and water level. The author analysis the relation between waterlevel oil production and precipitation as well. Confirm normal change of water level.Point out the index of earthquake forecasting. Discuss mechanism of underground waterlevel caused by earthquake.
