用计算机测定震源位置和发震时刻(以下简称地震定位)的全过程可分成四个主要环节:(1)震相数据处理;(2)正演问题:计算地震波走时;(3)反演问题:求解地震时空参数;(4)输出结果。下面根据我们的体会,对这四方面加以讨论,看看如何提高台网定位能力。一、震相数据处理震相数据是地震定位的基础。没有足够的、高质量的震相数据岂能获得可靠的定位结果?目前我国的六大电信传输地震台网(北京、沈阳、兰州、上海、成都和昆明)由高精度
The whole process of determining the location of the source and the time of the occurrence of the earthquake (hereinafter referred to as the earthquake location) by computer can be divided into four main phases: (1) seismic phase data processing; (2) forward problem: calculating the travel time of the seismic wave; (3) : Solving seismic space-time parameters; (4) Outputting results. The following based on our experience, to discuss these four areas, to see how to improve network positioning capabilities. First, the seismic data processing seismic data is the basis of seismic positioning. At present, the six major telecom transmission seismographs in China (Beijing, Shenyang, Lanzhou, Shanghai, Chengdu and Kunming) are constructed with high-precision
