Abstract

There is disclosed a method of detecting failures or anomalies of a large number of sensor terminals without using manpower or expensive equipment in the seismic exploration business. The method includes preparing a plurality of sensor terminals having sensors that detect vibrations from outside, the plurality of sensor terminals receiving the vibrations and outputting vibration reception signals, and comparing a first vibration reception signal output by a first sensor terminal with a second vibration reception signal output by a second sensor terminal, thereby detecting if one of the first sensor and the second sensor is failed or anomalous.
