摘要
本文分析了乌什6.4级地震的序列特征,该序列是主—余震型,余震空间分布呈北西向,序列衰减正常。现场开展了多种测震学预报方法的研究,在一定条件下某些方法对中强地震有一定的预报信息。利用强余震的准周期性等方法较好地预测了5.2级余震。
The characteristics of the Wushi earthquake Ms 6.4 sequence which is of a mainshock-afer-shock type, have been analyzed in this paper. The spatial distribution of the aftershocks areoriented NW, and the sequence attenuation is normal.Research on, several seismometry methodsfor prediction has been carried out in the seismic field, and some methods can provide a cer-tain information for predicting moderate and strong earthquakes under given conditions. Theaftershock Ms 5.2 was well predicted asing the method of quasi-periodicity of the strong af-tershocks and other methods.
