Validity of Earthquake Prediction

地震预测的有效性

It was in the early evening hours of February 4, 1975, when an earthquake of magnitude of 7.3 struck the densely populated town of Heicheng, in the Liaoning Province, in northeast China. As expected, because the magnitude was great and the area highly populated, damage to Haicheng and to neighboring towns was extensive. However, what was different about this earthquake is that very few lives were lost. The reason for the low death toll was that the occurrence of this earthquake had been successfully predicted.

1975年2月4日傍晚，辽宁海城市发生里氏7.3级地震。由于此次地震级数较大且震区人口稠密，海城及周边城镇都遭受了巨大破坏。然而，与以往不同的是，这次地震导致的死亡人数却很少，这就要归功于地震的准确预报了。
