On 4 February 1975, an
earthquake measuring 7.3 on the
Richter Scale hit the city of Haicheng, which at the time had approximately 1 million residents. However,
seismologists sent out warnings about this earthquake a day earlier and ordered evacuations. Because of this correct prediction, many lives were saved. This was the first successful earthquake prediction in history. Further aiding the prediction, cats and other animals are also said to have acted strangely in the days leading up to the earthquake. However, there are some questions as to the validity and accuracy of these reports. ==Administrative divisions==
