THE DESIGN AND APPLICATION OF A LATER SEISMIC PHASES AUTOMATIC MARKING PROGRAM

To increase the value and utilization ratio of seismic data,Stations ought to mark as more clearly phases as possible.But marking seismic phases will cost lot of time and energy.In order to mark seismic phases accurately,a program that can automatically mark later seismic phases using pre-designated phase travel time table files and phase file is developed.The program works normally in Hongsan benchmark seismic station and plays an active role in daily work.
