The 1975 Haicheng earthquake measuring 7.3 on the Richter Scale occurred at 19:36 CST on February 4, 1975 in Haicheng, Liaoning, China, a city that at the time had approximately 1 million residents.
Seismologists sent out warnings about this earthquake a day before it took place and ordered evacuations. This successful prediction saved many lives. This was the first successful earthquake prediction in history. In the days leading up to the event cats and other animals were thought to have acted strangely. There are some claims that this aided in the prediction of the earthquake. The validity and accuracy of these reports is questionable [1] as "It was the foreshock sequence that gave (Chinese officials) the solid prediction." [2]
