本文对1969年以前发生在中国境内的5级以上的地震震害进行了总结。提出了历史震害分布规律及震害出现次数与烈度曲线函数关系,给出震级与震害最大距离的关系公式。这些规律和公式,对震害预测和烈度小区划有一定参考价值。 我国有丰富的地震灾害记录,但至今还散落在各种地震文献之中,如果把这些资料进行整理,用之于生产建设,将有一定的实际意义。 据此目的,本文对公元前1177年至1969年间发生的地震进行了总结,并着重研究了震害情况。
This article summarizes the damage caused by earthquakes of magnitude 5 or above occurred before 1969 in China. The distribution law of historical earthquake damage and the relationship between the number of occurrence of earthquake damage and the curve of intensity are put forward, and the relation formula between the magnitude and the maximum distance of earthquake damage is given. These laws and formulas have certain reference value for the earthquake damage prediction and intensity subdivision. China has a wealth of records of earthquake disasters, but so far it is still scattered in various seismological documents. If these data are collated and used in production and construction, it will have some practical significance. For this purpose, the paper summarizes the earthquakes that occurred between 1177 BC and 1969 BC and focuses on the earthquake damage.
