Simualtion results of seismic-acousti wave propagation from regions around Sumisu Caldera and Sofu Seamount

Reciprocal calculation results Sumisu_M.KMB06_???.csv and Sofu_M.KMB06_???.csv are the results of T-wave analysis from reciprocal simulation results around Sumisu Caldera and Sofu Seamount, respectively. The CSV files contain the following data: lon lat dep edist Tt Th1 Th2 Ab AT bath kmbfs efficiency duration Peak delay lon, lat, and dep are hypocenter location information, edist is epicentral distance, and bath is the bathymetric depth just above the epicenters. kmbfs is a hypocenter depth of "kilometers below the seafloor." Tt, Th1, Th2, and AT are theoretical T wave traveltime, half-value starting, half-value ending, and maximum T wave amplitude, respectively. Ab is the maximum amplitude of the body wave portion. The efficiency is AT/Ab, duration is Th2–Th1, and peak delay is the peak arrival time of the T wave from Tt. The exp, dip and ten are explosion, dip-slip, and tensile source. Forward simulations Ep?_ten.csv are forward simulation results from Ep2 and Ep5. lon lat dep edist Tt Th1 Th2 Ab AT efficiency duration Peak delay lon and lat are locations of seismic stations within simulation regions. Others are the same in reciprocal calculation results. Envelopes SAC format files of synthesized envelopes of reciprocal calculations are stored. The 180506 and 231009 are the results from regions around Sumisu Caldera and Sofu Seamount, respectively. Detailed information can be obtained from the SAC header.
