Data Files from "Source mechanisms and rupture processes of the December 26th, 2006 Pingtung Earthquake doublet as determined from the regional seismic record" Shiann-Jong Lee, Wen-Tzong Liang and Bor-Shouh Huang Institute of Earth Sciences, Academia Sinica INTRODUCTION This note describes the results in computer readable files from our paper "Source mechanisms and rupture processes of the December 26th, 2006 Pingtung Earthquake doublet as determined from the regional seismic record". We use regional ground motion full waveform records, including data recorded by BATS and TSMIP stations, to investigate source rupture processes of Pingtung earthquake doublet. The preferred fault plane of the first event is determined from BATS CMT solution that dips toward the east. The fault plane of the second earthquake is determined from Harvard CMT solution which dips toward the west. DATA FILES There are 1 file and 2 sub-directories on the attached DVD-ROM, under the directory of \LeeSJ: (1) readme.txt -- this note in an ASCII text file. (2) 200612261226 (Sub-directory) -- 79 ASCII text files of the final slip distribution and snapshots for the first event. (3) 200612261234 (Sub-directory) -- 60 ASCII text files of the final slip distribution and snapshots for the second event. EXPLANATION OF THE FILES (1) slipsum.xyz The final slip distribution of the Pingtung earthquake doublet. The fault area was divided into several sub-faults. Each sub-fault has the dimension of 5 km x 5 km. The fault has the geometry of strike = 349 degree from the north, and dip = 53 degree to the east for the first event. The second event has the geometry of strike= 151 degree, and dip = 55 degree to the west. The files 200612261226\slipsum.xyz and 200612261234\slipsum.xyz have the sub-faults of 612 and 560 sub-faults, respectively. The first column indicates the number of sub-faults. The second, third, and 4th columns indicate the longitude (degree), latitude (degree) and depth (km) of the sub-fault-grid points. The 5th column is the amount of final slip in centimeter. The 6th column is the rake angle on the subfault. (2) snap_*.xyz The snapshots of the Pingtung earthqauke doublet. The "*" in the file name indicates the time stamp of rupture processes (by every one second). The faults have the same geometry as described above. The first column indicates the number of sub-faults. The second, third, and 4th columns indicate the longitude (degree), latitude (degree) and depth (km) of the sub-fault-grid points. The 5th column is the amount of cumulative slip (cm) on the subfault. Thus, the slip amounts in the latest snapshot should be the same as those in slipsum.xyz. The 6th column is the rake angle on the subfault at each moment.
