摘要

2009年3月22日,在贵州省威宁县哈喇河乡与双龙乡一带发生了M4.7级地震,本文从地质构造背景、地震基本参数、地震序列特征等方面对这次地震进行了初步分析。得出这次地震为前震-主震-余震型,同时威宁地区3级地震持续活动对该区中强地震的短临预报具有一定的指示意义。
The M 4.7 earthquake occurred in Weining County of Guizhou Province on March 22,2009.Based on the analysis of the seismogeological background,basic parameters of the earthquake and features of the seismic sequence;this article points out that the earthquake sequence is mainly a foreshock-mainshock-aftershock type.Strength of small-scaled earthquakes indicates that medium-strong earthquakes will occur in Weining County in the near future.
