Haicheng (Simplified: 海城; Traditional: 海城; Hanyu Pinyin: Hǎichéng) is a county-level city of Anshan City, Liaoning Province, in the People's Republic of China. It is located about 200 kilometers from Shenyang, the capital of Liaoning Province.
On February 4, 1975, an earthquake measured 7.3 on the Richter Scale hit the town of Haicheng, a population of about 1 million. However, seismologists sent out warnings about this earthquake a day ago and ordered evacuations. Because of this correct prediction, many lives were saved. This was the first successful earthquake perdiction in history.
Haicheng is remarkable and well-known for its success in Chinese earthquake prediction research. Other than the 1975 Haicheng earthquake prediction, another successful earthquake prediction was made a week before the M5.4 Gushan-Pianling Earthquake in Haicheng and nearby Xiuyan city.
