Abstract: Abstract Japan is one of the most earthquake-prone countries in the world. Earthquakes and tsunamis have repeatedly claimed many human lives and properties. The Japan Meteorological Agency has been operating a computer system for preventing disasters from earthquakes and tsunamis. NEC Corporation was contracted to develop its second generation system in 1993. In this paper we describe the overviews of the system, the configuration necessary for higher reliability, and the warning mechanisms concerning a damaging earthquake. In particular, the warning mechanisms have several advanced features, and the Earthquake Early Warning notifies the public about the approach of a strong earthquake before it actually arrives. In addition, the warning mechanisms can predict the possibility of tsunami generation within 3 min after a quake. Moreover, we show the system’s activities around the time of the massive earthquake on March 11, 2011, and then describe the necessity for further functional improvements to the system.
