Analysis of Seismic Phase Based on Theoretical Travel Time Table
Abstract We explore the relations among the phase travel time, epicentral distance and focal depth by using theoretical seismic phase travel time tables. Results show that seismic phase varies when changing the epicentral distance or focal depth, there exists positive or negative correlations between them, and part of seismic phase travel time will truncate as epicentral distance or focal depth increases. These laws can offer a convenient approach to analyze the earthquake event.
Key words :
theoretical travel time table
seismic phase
epicentral distance
