Patent ID: 11906678
Assignee: NEC CORPORATION
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 6:
7. A non-transitory computer readable-medium having instructions stored therein, which when executed by a processor in a seismic observation device cause the processor to:
receive input of time-series data of measurement values of a vibration from one or more sensors;
retrieve a trained model that is trained according to machine learning;
analyze, by the trained model, the time-series data to determine a time period of the time-series data that is a processing target;
detect, during the time period, a trigger indicating a vibration different from a normal vibration; and
acquire, based upon detection of the trigger, a likelihood of classifying a cause of the vibration indicated in the time-series data in the time period, wherein the cause is classified as at least one of a near-field earthquake, a far-field earthquake, a low frequency earthquake, an artificial earthquake, a micro-earthquake, and a volcanic earthquake.
