Moment rate functios of shallow very low frequency earthquakes off the Cape Muroto and Kii Channel, along the Nankai Trough, Japan
收藏资源简介：
Moment rate functions of shallow very low frequency earthquakes (VLFEs) that occurred off the Cape Muroto and Kii Channel. A similar catalog but for southeast off the Kii Penisula can be downloaded from https://doi.org/10.5281/zenodo.5211090 This data set is the supplement of "Takemura, S., Baba, S., Yabe, S., Emoto, K., Shiomi, K., & Matsuzawa, T. (2022).

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<br> 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<br> 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. Data Set S1<br> CSV format file of shallow VLFE swarm catalog. Origin time (JST), epicenter locations, seismic moments, durations, moment magnitudes, VRs, and swarm indexes of each shallow VLFE. The “-” in the swarm index column means that this shallow VLFE does not belong to shallow VLFE swarms. <strong>Citation</strong> Takemura, S., Baba, S., Yabe, S., Emoto, K., Shiomi, K., & Matsuzawa, T.
