<p>PROBLEM TO BE SOLVED: To obtain a seismic-wave measurement device that can properly test calibration sensitivity. SOLUTION: An earthquake-wave detection signal being detected by a detector 2 of a building 1 is amplified by a signal amplifier 3 and is inputted to a calculator 6 of a central operation room 4 via an interface part 5 for monitoring an seismic wave. Also, when the calibration test of the detector 2 is performed, a detector 7 for calibration is provided near the detector 2, and furthermore, a vibrator 8 for hitting and vibrating the detector 2 and the detector 7 for calibration is provided. According to a command signal from an in-site calibration unit 9, the detector 2 and the detector 7 for calibration are hit and vibrated by the vibrator 8. The in-site calibration unit 9 outputs the detection signal from the detector 7 for calibration which is generated on vibration by the vibrator 8 to the calculator 6 via a communication interface part 13 and the interface part 5.</p> |
