Predicting the 1975 Haicheng Earthquake
by Kelin Wang, Qi-Fu Chen, Shihong Sun, and Andong Wang
Abstract The publicized four-stage (long-term, middle-term, short-term, and im-
minent) prediction of the M 7.3 1975 Haicheng, China, earthquake once generated
worldwide fascination. Yet the prediction process has remained mysterious because
of lack of reports on real-time documentation and details of how warnings were
issued. In the present work, study of declassified Chinese documents and interviews
of key witnesses have allowed us to reconstruct this important history. Our findings
indicate that there were two official middle-term predictions but no official short-
term prediction. On the day of the earthquake, a county government issued a specific
evacuation order, and actual actions taken by provincial scientists and government
officials also effectively constituted an imminent prediction. These efforts saved
thousands of lives, but the local construction style and time of the earthquake also
contributed to minimizing fatalities. Evacuation was extremely uneven across the
disaster region, and critical decisions were often made at very local levels. The most
important precursor was a foreshock sequence, but other anomalies such as geodetic
deformation, changes in groundwater level, color, and chemistry, and peculiar animal
behavior also played a role.
