The actual example of disaster prevention by this system is also described. In this field the problems caused by JMA, Japan Meteorological Agency, are discussed. The concluding remarks as follows: 1) Network alarm is effective for middle distance area, but risky because of the data interruption caused by the network error, 2) On-site alarm by FREQL or AcCo is useful for anywhere, even epicentral area, and 3) Early Earthquake Information distributed by JMA is full of error and useless for damage area because of too late warning.
