摘要
地震定位是地震学基本问题之一,如何提高地震定位精度是地震学研究重点。本文介绍地震定位技术在国内外的研究历史及进展,对目前存在的各种地震定位技术进行分类,概述基本原理及应用。详细介绍盖革经典定位法、双差定位法和微震定位方法中的波形互相关技术和震源扫描算法,并简单介绍微震定位技术在核试验监测及定位上的应用。
Earthquake locating is one of the basic problems in seismology, how to improve locating precision is always a key point. This paper introduces the history and development of earthquake locating methods at home and abroad, sorts the earthquake locating methods currently existed and outlines their basic theory and application. We emphatically introduce Geiger classical location, double difference location and microseismic location including waveform cross-correlation, source-scanning algorithm（SSA）. Finally, we simply introduce the application of microseismic location in monitoring and locating nuclear test.
