Catalog and moment rate function dataset of shallow VLFE southeast off the Kii Peninsula, in the Nankai subduction zone

Catalog

"VLFE_catalog_latestUTC" is the catalog file. Estimated origin time (JST), longitude, latitude, seismic moment, duration, seismic moment (half-value width), half-value width, Variance reduction, and estimated origin time (UTC) of each shallow VLFE are listed. 

"VLFE_catalog_SP_latestUTC" is the catalog file for shallow VLFEs evaluated via a single Küpper wavelet with various durations. 

Inversion results

YYYYDDMMHHMM is the directory name of a shallow VLFE that occurred in HH:MM DD MM YYYY (JST). 

YYYYDDMMHHMM_VR.dat: spatiotemporal variation of variance reduction in inversion procedure. 

YYYYDDMMHHMM_param.stfvlf: parameter file for inversion. Station names and their weight in inversion are listed.

YYYYDDMMHHMM_solution.png: Image file illustrating inversion result. 

YYYYDDMMHHMM_stf_optimal.sac: SAC format file for the estimated optimal moment rate function of a shallow VLFE. 

YYYYDDMMHHMM_stf_optimal.dat: ASCII format file for the estimated optimal moment rate function of a shallow VLFE.  Estimation errors were evaluated from five-time simulated annealing procedures for different random seeds. 

YYYYDDMMHHMM_solution_SP.png: Image file illustrating inversion result based on the single-pulse assumption.

YYYYDDMMHHMM_stf_optimal_SP.sac: SAC format file for the estimated optimal moment rate function of a shallow VLFE based on the single-pulse assumption.

YYYYDDMMHHMM_stf_optimal_SP.dat: ASCII format file for the estimated optimal moment rate function of a shallow VLFE based on the single-pulse assumption.
