[SSS12-P08] On S wave picking of the 2016 Kumamoto earthquake
Keywords:S wave, onset time, the 2016 Kumamoto earthquake
Recently, an abundance of seismic stations has been deployed in all over the world and plenty of seismic records have been obtained so automatic P and S wave picking techniques have been developed. Some of those techniques make use of STA/LTA , polarization of waveforms, and stochastic characteristics, and so on.
In this study, the author applied those S wave picking techniques for waveform data of the 2016 Kumamoto earthquake recorded by KiK-net underground stations and made some trials to pick S waves precisely and objectively.
