Abstract
A seismic sensor according to one or more embodiments may include: an acceleration measuring unit configured to repeatedly measure acceleration in three directions orthogonal to each other; and an index value calculator configured to operate in a measurement mode for calculating an index value of a magnitude of an earthquake based on a measurement result of acceleration in at least one direction by the acceleration measuring unit, and to operate in a standby mode with less power consumption than power consumption in the measurement mode. Then, the acceleration measuring unit monitors establishment of an activation condition that N times (M≥N≥2) measurement results in consecutive M times (M≥2) measurement results of acceleration in a predetermined direction exceed an acceleration threshold value. When the acceleration measuring unit detects establishment of the activation condition, the index value calculator transitions from the standby mode to the measurement mode.
