Table 1. Fault parameters of our preferred model. We define the location of each fault as the center. The unit of length, width, and depth is in kilometers. Dip, strike and rake are in degrees, and slip is in meters. In the lowest row, the fault parameters from the CMT solution (NIED Earthquake Mechanism Search (http://www.fnet.bosai.go.jp/event/search.php?LANG=en)) are listed for comparison.
