Abstract

See full text

An exploration system includes an artificial seismic source, sensor terminals, an environmental sensor, and a computer, wherein each of a plurality of sensor terminals is provided with a velocity or acceleration sensor which detects vibration generated by the artificial seismic source, and an identifier which is unique to the velocity or acceleration sensor; the environmental sensor detects an external environment which influences the velocity or acceleration sensor; and the computer stores a deterioration model which possibly indicates, as a degree of deterioration, performance deterioration of the velocity or acceleration sensor by providing information about the external environment as a variable, associates, with the identifier, the information about the external environment detected by the environmental sensor, stores the information about the external environment as a usage history, and determines a deterioration state of the velocity or acceleration sensor or the sensor terminal on the basis of the deterioration model.
