CMT catalog of small-to-moderate earthquakes at off Ibaraki region

CMT catalog of small-to-moderate earthquakes at off Ibaraki region The CMT solutions are obtained in “CMT inversion for small-to-moderate earthquakes applying to dense short-period OBS array at off Ibaraki region” by Lina Yamaya, Kimihiro Mochizuki, Takeshi Akuhara, Shunsuke Takemura, Masanao Shinohara, and Tomoaki Yamada. Aftershocks of the 2011 Tohoku-oki earthquake with Mw 9.0 March 11, 2011 to September 17, 2011 Mw2.5–4.5 Data format: Date (“YYMMDDHHMMSS”), lng, lat, dep, Mrr, Mtt, Mff, Mrt, Mrf, Mtf, 0, 0, exponent (dyne-cm), VR, 68% confidence interval of Kagan angle by bootstrap result, 95% confidence interval of Kagan angle, Mw The seismic velocity model is the input file for using Open SWPC. Note that the details are shown in "Sedimentary structure from multi-mode ambient noise tomography with dense OBS network at the Japan Trench" by Lina Yamaya, Kiminiro Mochizuki, Takeshi Akuhara, and Kiwamu Nishida.
