Earthquake Sensor Alarm System (ESAS)
When Earthquake occurs, people needs to evacuate immediately.
Nuclear plants, chemical plants and trains must be shut down.

5seconds extra warning can be the difference between life and death
80% of deaths could be prevented by early and accurate alarms.

EQ guard has sensor insideIt detects initial small vibration (P wave) and issue
alarm immediately before big shaking (S wave) arrives.
So, people can evacuate before strong shaking starts.
Real-time display of the seismic intensity of eachobservation point on the map
 Control signals of EQ guard can be issued to shut
down chemical plants, nuclear facilities etc.
beforehand.
Customers Japan:1000
Indonesia, Korea, Turkey, Romania, PNG

The benefit of this system for DRR◆Early warning system based on network of EQ guard

1.EQ guard can work as a stand alone, andalso can work as a local network withseveral installations.
2.It is possible to construct a regional
earthquake alarm system by making NW ofEQ guard.
3. This system works without nation-wide
dense seismometer network

Computed hypocenter location and list of estimated shaking intensity of JMA definition.
Obs: Observed JMA intensity,Est: Estimated intensity from hypocenter location and intensity magnitude.
Hypocenter and magnitude are calculated by the use of P wave arrival times and shaking
intensity measured within 4 sec from P wave arrival, which are stored on the disk of data
center of Challenge Cor. And are sent from stations of EQ-GARD III.
There are difference in the definition between Shaking intensity magnitude Richtermagnitude.
