淮河流域中游顺治年间地震灾害考证研究

A Textual Research on Earthquake Disaster in the Middle Reaches of Huaihe River Basin during the Reign of Shunzhi

在整理淮河流域中游顺治年间地震灾害史料的基础上,结合现代地震学及地质学原理,对顺治九年春发生于霍山东北的地震灾害进行了考证。经考证,得到以下几个方面的认识:(1)此次地震的发震时间为"二月十四日夜",而非"二月十四日丑时",地震发生于夜间而非凌晨;(2)震中烈度为8度,较之之前认定的7度略高;(3)震中位置描述应为"31.5°,116.5°",而"31°5′,116°5′"为错误描述;(4)震级经计算为6?,比原来认定的6级略高;(5)震源深度约为7.8公里,为典型的浅源地震。

On the basis of collating the historical data of earthquake disasters in the middle reaches of Huaihe River basin during the reign of Shunzhi,combining with the principles of modern seismology and geology,the earthquake disasters occurred in the northeast of Huoshan in the spring of the ninth year of Shunzhi are studied.Through research,the following aspects of understanding are obtained:(1)The earthquake occurred on the night of February 14,not on the Chou time of February 14.Namely,the earthquake occurred at night rather than in the early morning;(2)The epicenter intensity is 8 degrees,slightly higher than the previously identified 7 degrees;(3)The description of epicenter location should be"31.5°,116.5°",and"31°5’,116°5’"is the wrong description;(4)The magnitude was calculated to be 6?,slightly higher than the original level of 6;(5)The focal depth of this earthquake is about 7.8 km,suggesting a typical shallow earthquake.
