Our study seeks to obtain a more detailed 3D velocity structure for the region surrounding the Chi-Chi source volume, both before and after the Chi-Chi earthquake. Through tomographic inversion, we have computed 3D Vp and Vp/Vs models using the high-quality data set from local earthquakes as recorded by the Taiwan Central Weather Bureau Seismographic Network (CWBSN).
We have selected 760 Chi-Chi aftershocks with 12,568 P- and 9,915 S-wave arrival times that are used in this study. In order to examine whether the large Chi-Chi earthquake sequence has changed the crustal properties, we have used another data set selected from the CWBSN database from 1993 to 1999. This includes arrival times of 22,500 P- and 14,460 S-wave arrival times from 975 events . . . [Full Text of this Article]
