Abstract
Power consumption of a seismic sensor is suppressed. The seismic sensor is operated in a power-saving mode and a measuring mode in which the power consumption is larger than that of the power-saving mode. The seismic sensor includes: a measuring part configured to measure an acceleration; an index calculator configured to transition from the power-saving mode to the measuring mode to calculate an index value indicating a size of an earthquake when the acceleration measured with the measuring part exceeds a first threshold; and a threshold adjuster configured to change the first threshold so as to increase the first threshold relative to a predetermined reference value when a tendency of the acceleration measured with the measuring part satisfies a predetermined condition.
