The benefit of Earthquake Early Alarm 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 Guard III.
There are difference in the definition between Shaking intensity magnitude Richtermagnitude.

80% of deaths could be prevented by 5 seconds prior alarm if
people were well trained. Evacuation drill is very important.
