摘要
日本是世界上地震海啸发生最频繁的国家之一。从 1 94 1年开始 ,日本气象厅就建立了自己的海啸预警系统。自 1 993年又一次遭受海啸灾害后 ,这些经历促使日本气象厅 (JMA)开始研制基于数值预报技术的新一代海啸预警系统。该海啸预警系统包括地震监测网、基于数据库技术的快速数值预报以及基于卫星通讯的海啸预警产品快速分发系统这三部分。
Japan is the one of the most serious countries suffered from the tsunani disasters.Since 1941, the Japan Meteorological Agency (JMA) has conducted tsunami forecasting for Japan. However, huge tsunamis still cause damage and kill many people.Especially after suffered the disaster in 1993. These experiences caused the development of more prompt and accurate tsunami forecasting for the purpose of survival. The new system has the following three sections: New seismograph network and P-wave magnitude determination,Rapid interpolation numerical tsunami model and Satellite based system for dissemination of information.
