Description
3D CMT inversion solutions of moderate-size earthquakes along the Nankai Trough, version 2.1
In this version, full components of moment tensors (including an isotropic one) for analyzed earthquakes are listed. The previous version only included deviatoric components of the CMT solutions, although CMT inversions were conducted by using six-element moment tensors.
We also revised CMT solutions of Mw 7.2 and Mw 7.5 occurred on 5 September 2004, southeast off the Kii Peninsula, Japan.
- Analyzed periods: April 2004 to August 2019
- The method and results are described in the submitted preprint.
