SF-CMT catalog of moderate-to-large earthquakes at Japan Trench subduction zone

The CMT solutions are obtained in “Impact of offshore seismograph network and 3-D seismic velocity structure model on centroid moment tensor analysis for offshore earthquake: Application to the Japan Trench subduction zone” by Lina Yamaya, Hisahiko Kubo, Katsuhiko Shiomi, and Shunsuke Takemura.

Earthquakes at the Japan Trench subduction zone

April 1, 2017 to March 31, 2024

Mw of 5.2–7.0

Data format: YYYY-MM-DD (JMA origin at JST), time (JMA origin at JST),  YYYY-MM-DD(JMA origin at UTC), time (JMA origin at UTC], longitude, latitude, depth, Mrr, Mtt, Mff, Mrt, Mrf, Mtf (Nm), time shift, variance reduction, Mw

The centroid times of the SF-CMT and F-CMT solutions can be obtained by adding the time shift to the JMA origin time (columns 1 and 2, or 3 and 4).

"SFCMT.zip" and "FCMT.zip" files include SF-CMT and F-CMT solutions for the earthquakes and station lists.
