日本是世界上最容易发生地震的国家之一。地震和海啸一再夺走许多人的生命和财产。日本气象厅一直在运行一个预防地震和海啸灾害的计算机系统。NEC公司于1993年签约开发其第二代系统。在本文中，我们描述了该系统的概述，更高的可靠性所需的配置，以及有关破坏性地震的预警机制。特别是，预警机制有几个先进的功能，地震预警通知公众的方法，一个强大的地震之前，它实际上到达。此外，预警机制可以预测地震发生后3分钟内发生海啸的可能性。此外，我们显示了系统的活动在2011年3月11日大地震的时间，然后描述进一步的功能改进的系统的必要性。
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.
