1976 Tangshan Earthquake - Early Warnings and Predictions

Early Warnings and Predictions

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. City dwellers from the "downtown" area who had fish discovered that the fish were restless, jumping out of the aquarium as if wanting to escape, therefore some animals may have anticipated the earthquake.

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 and August 5, 1976. 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 Qinglong was official Wang Chunqing (王春青).
