More Information
Summary:Seismic device includes acceleration sensor (10) that successively outputs an acceleration value according to magnitude of acceleration of applied vibrations, earthquake determining unit (11) that differentiates and determines an earthquake and a shock from the acceleration value output from acceleration sensor (10), and seismic intensity calculator (12) that calculates a seismic intensity equivalent value from the acceleration value output from acceleration sensor (10). Further, earthquake determining unit (11) differentiates and determines an earthquake and a shock from a generation pattern of binary values (0 and 1) binarizing the acceleration value output from acceleration sensor (10) with the predetermined threshold value.
