In order to reduce earthquake disaster of railways, we should improve the earthquake-proof performance of railway facilities. Meanwhile, it is important to reduce earthquake disaster by controlling the train operation promptly and appropriately in case of an earthquake. In recent years, valuable knowledge is being accumulated to give an urgent alarm for earthquakes due to the development of the real-time seismology. Japan Meteorological Agency (JMA) and other governmental organizations have improved the nationwide earthquake observation network and planned to distribute prompt earthquake information (Earthquake Early Warning information). Under the circumstances, Railway Technical Research Institute and JMA have jointly developed the data processing system and the application system of this information. This paper introduces the main results.
