Abstract

This paper describes a method for calculating the earthquake energy class for the Kamchatka region from coda records in the 0.8–1.8 Hz frequency band. The method is based on an empirical correlative relationship between the coda level and the Fedotov earthquake class. The coda level is found as the mean power of the ground velocity in an interval of 30 s. Five seismic dipping zones have been identified in Kamchatka, each having its own expression for converting the coda level to the energy class.

基于尾声的地震能级

摘要

本文介绍了一种从0.8-1.8 Hz频段的尾声记录计算堪察加地区地震能量等级的方法。该方法基于尾声水平与费多托夫地震等级之间的经验相关关系。尾声级是在30 s间隔内的地面速度的平均功率。在堪察加半岛已经确定了五个地震浸没带，每个浸没带都有其自己的表达方式，可将尾声级转换为能量等级。
