Moment rate functios of shallow very low frequency earthquakes southeast off the Kii Peninsula, along the Nankai Trough, Japan

Moment rate functions of shallow very low frequency earthquakes (VLFEs) that occurred southeast off the Kii Peninsula, along the Nankai Trough

The method and related discussions were described in the JGR paper.

Included files

• YYYY-MM-DDThhmmssparam.stf
  Parameter file for the Monte-Carlo-based simulated annealing estimation for a shallow VLFE occurred at hh:mm:ss on DDth MM YYYY (JST). Detection time, correlation coefficient, longitude, latitude, ratio (internal parameter), template index (internal parameter), assumed strike angle, dip angle, rake angle, source grid index (internal parameter), the number of the used stations, station list are included.
• YYYY-MM-DDThhmmss_STF.dat
  Moment rate function for a shallow VLFE occurred at hh:mm:ss on DDth MM YYYY (JST). The optimal and original simulated annealing estimations are listed in the 2nd and 3rd columns, respectively. The time from the origin is represented in the 1st column
• VLFE_catalog.csv
  CSV format file of Shallow VLFE catalog from Apr. 2004 to Mar. 2021.  Origin time (JST), origin time (UTC), longitude (ºE), latitude (ºN), seismic moment (Nm), duration (s), VR (%), and Mw are listed.
