1975年2月4日19时36分,一道蓝光划破宁静的夜空,顷刻间辽南大地山摇地动,房倒屋塌…….海城地区发生了7.3级大地震!然而,身居震中的人们却安全无羌,没有遭到重大伤亡.这是因为五个半小时以前,省里根据地震部门的预报意见,及时地疏散了震中区的人民群众.海城地震发生在人口稠密、现代工业集中的辽宁腹地,波及6个市,10个县,灾区总人口835万人,死亡率只占2/10 000.如果震前没有预报,按相同人口密度发生7级地震的死亡率估算,就要有10多万人死于地震的魔掌.这个数字同美国、印度一些学者的预测是一致的.可
At 19:36 on February 4, 1975, a blue light pierced the quiet night sky, instantaneous liaoning earth mountain rocking, housing collapsed house ... .... Haicheng area 7.3 magnitude earthquake! However, living The people in the epicenter were safe and without Qiang and had not suffered any major casualties because the province evacuated the masses of the epicenter in a timely manner according to the prediction of the earthquake department five and a half hours earlier.The Haicheng earthquake occurred in a densely populated, In the hinterland of Liaoning, where modern industry is concentrated, it spread to 6 cities and 10 counties with a total population of 8,350,000 and a death rate of only 2/10 000. If there is no forecast before the earthquake, the death rate of an earthquake of magnitude 7 with the same population density is estimated , More than 100,000 people will have died in the clutches of the earthquake, which is consistent with the predictions made by some scholars in the United States and India.
