WIPO Patent Application WO/2021/033547
Kind Code:
A1
Abstract:
This seismic observation device is provided with: a waveform acquisition unit which acquires waveform data of a given period that includes an observation start time of a P-wave; a delay time identification unit which inputs the waveform data to a learned model and acquires a delay time between the observation start time of the P-wave and an observation start time of an S-wave from the learned model; and an observation time estimation unit which estimates the observation start time of the S-wave on the basis of the observation start time of the P-wave and the delay time.
