新30号井水位自2006年8月22日开始数字化观测，截止到2009年12月，多次出现大幅度、快速升降异常现象。笔者通过多次周围环境的实地调查、统计与分析，认为异常由森林公园人工湖湖水渗流导致，不是地震前兆异常。

The new well No.30 has begun its digitalized observation since August 22, 2006. Until December 2009, several drastic, rapid and abnormal movements of water level in new well No.30 have occurred many times. Based on several investigations, statistics and analysis about field environment, it is found that several drastic, rapid and abnormal movements are caused by seepage action of the artificial lake in Forest Park, and not seismic warning signs.
