Background
Giving evacuation instructions and stopping the facilities in the event of an earthquake have beenmostly human-operated, which often resulted in inadequate response to the disasters. Also, theconventional drop-ball type seismographs do not allow the sensitivity settings to be changed afterinstallation. Therefore, the false alarm and/or detection failure have been inevitable at some level. Inaddition, since the accurate seismograph equipped with the oscillatory waveform recording function
requires specialized agencies for its operation, the visual check at the actual site was the only way toassess the detailed situation. Therefore, the development of a new digital seismograph that is robustand easy to handle is needed to solve those existing issues listed above.

Exposition of the Solution[Seismic Monitoring System]
It makes prompt announcements to the area and vicinity, conduct safety shutdown of the equipment,
and shut off gas and water valves on detecting the earthquake in order to limit the damage and preventthe secondary disasters.
http://www.imv.co.jp/e/products/seismometer/watch/tm0013/[Long period vibration monitoring system]
Assess the situations at normal times and post-disaster by checking the seismic isolation or seismic
resistance of the large structures, and recording vibration waveforms caused by the earthquake or otherfactors.
