摘要
介绍DIMAS软件中定位软件的使用方法,阐述方位角确定原理。结合实例,给出近震、远震、极远震的定位结果,详细分析定位过程中产生误差的原因和提高定位精度的方法。
The application of DIMAS software for earthquake location is introduced and the principle to determine the azimuth is expounded. The effect of earthquake location, include near earthquake, teleseimics and very far earthquakes is demonstrated. The reasons for location error are analyzed in detailed and the methods for improving the location precision are proposed.
