| Abstract: | 85 earthquakes with higher location precision are selected from the catalog given by the Heilongjiang regional digital seismic network were selected. By using the observed travel time data of the selected earthquakes, an underground medium velocity model is derived through inversion technique and a local travel time table for Wudalianchi volcanic area is established based on the obtained single-layer average velocity model. Comparison is made between the new travel time table and the J-B table by practical testing, and the result shows that the precision of data processing is obviously higher when the new travel time table is used. |
