| Abstract: | With the development of large scale digital earthquake monitoring system,how to use abundant digital seismic waveform data in the earthquake location to improve the location precise is the main purpose of this paper.From author's point of view,the DD(Double Difference)algorithm with cross correlation of waveform is a good choice with some prospects,in this paper the basic theory and development course of DD,practical using process in seismic network and some possible problems appearing in wide use of seismic networks have been analysed.The possibility of application in earthquake location and the direction of development of DD with cross correlation of waveform are also discussed. |
