在现代社会中,人们通过精确地计算来划分地震等级。但在古代社会中,并没有系统的完备的震级划分标准,那么如何确定古代地震的震级。本文以明代华县地震为例,根据史料中相关数据的记载,对比现代地震震级的划分,从而对古代地震的震级做出一个初步的判定,希望对研究古代地震有一定的帮助。 In modern society, people classify the magnitude of an earthquake by precisely calculating it. However, in ancient society, there is no systematic and complete criteria for the classification of magnitude, so how to determine the magnitude of ancient earthquakes. Taking the Huaxian earthquake in the Ming Dynasty as an example, this paper compares the magnitude of modern earthquakes with the data of historical records and makes a preliminary judgment on the magnitude of ancient earthquakes. It is hoped that it will be helpful to the study of ancient earthquakes.
