地震定位研究及应用综述

Study of seismic location methods

地震定位是地震学中最经典、最基本的问题之一,提高定位精度也一直是地震学应用研究的重要课题之一。本文就目前各种地震定位方法进行了大体分类并概述了基本原理及其应用,介绍了目前在国内各实时地震观测系统中应用的台网定位方法,同时将部分台网方法应用于黑龙江省绥棱爆破的定位。

Earthquake locating is one of the classic and basic problems in seismology, and to improve locating precision is still an important problem in seismological application study. Quiddity of earthquake locating is computing a minimum of objective function. There are some differences between obsevration travel-time and theory travel-time of both stations and imaginal hypocenter. Many kinds of methods of earthquake location are developed by 3D-velocity model. This paper sorts all earthquake locating methods currently used and summarizes basic theory and application of them. It introduces network locating methods used by each earthquake real-time observation system in China, at the same time some of these methods were used in blasting locating in Suiling, Heilongjiang Province.
