1975年2月4日19时36分,海城、营口地区发生强烈地震。这次地震特点是:震级高,为7.3级,震中裂度为9度;面积广,破坏性大;震区人口较稠密,气候严寒。由于各级党委重视,加强了领导,采取了有力的防震措施,群众作好抗震准备,临震预报及时准确,因而大大减少了人员伤亡。地震造成的人员伤亡和建筑物的破坏,是在极短时间内发生的,与核武器袭击造成的后果有些类似。为总结这次救治工作经验,做好 At 1936 on February 4, 1975, a strong earthquake hit Haicheng and Yingkou areas. The earthquake is characterized by: a high magnitude of 7.3, the epicenter rupture of 9 degrees; a wide area, destructive; quake zone population is more dense, the climate is cold. Due to the emphasis attached by party committees at all levels, the leadership has been strengthened and vigorous measures against earthquakes have been taken. The masses are prepared for earthquake resistance and the prediction of impending earthquake is timely and accurate, thus greatly reducing casualties.
