1976 Tangshan earthquake - Wikipedia, the free encyclopedia
[edit] Early warnings and predictions
Many people in Tangshan reported seeing strange lights (the so-called earthquake light) the night before the earthquake[citation needed]. Well water in a village outside of Tangshan reportedly rose and fell three times the day before the earthquake. Gas began to spout out of a well in another village on July 12 and then increased on July 25 and July 26 (references needed).
More than half a month before the earthquake struck, Wang Chengmin (汪成民) of the State Seismological Bureau (SSB) Analysis and Prediction Department had already concluded that the Tangshan region would be struck by a significant earthquake between July 22, 1976 to August 5, 1976.[1] Abnormal signals were mentioned for Beijing, Tianjin, Tangshan, Bohai and Zhangjiakou regions. Wang made an effort to publicize the information to 60 people. One of the people listening in was Qinglong official Wang Qingchun (王青春).[1]
