【Abstract】 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.更多还原
