CPC G01V 1/307 (2013.01) [G01V 1/008 (2013.01); G01V 2210/63 (2013.01)] | 4 Claims |
1. A seismic observation device comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to:
acquire waveform data for a predetermined period including an observation start time of a P wave;
input the waveform data to a trained model and acquiring, acquire, from the trained model, a delay time from the observation start time of the P wave to an observation start time of an S wave; and
estimate an observation start time of an S wave corresponding to the acquired observation start time of the P wave based on the observation start time of the P wave and the delay time.
