The other way of reducing earthquake disaster is to control the train operation promptly and appropriately in case of an earthquake. The Railway Technical Research Institute (RTRI) had developed an urgent earthquake detection and alarm system (UrEDAS) mainly for Shinkansen and put it into practical use. Valuable knowledge is being accumulated to give an urgent alarm for earthquakes due to the development of the real-time seismology in recent years. The Japan Meteorological Agency (JMA) and other governmental organizations are improving the nationwide earthquake observation network and planning to distribute prompt earthquake information (Earthquake Early Warning information; EEW information). Under the circumstances, RTRI and JMA have developed the data processing system of this information and the application system of this information to an earthquake quick alarm system of railways.<br> This paper presents new methods to estimate the hypocenter and magnitude in a short time after the detection of P waves, which are called the B-Δ method, territory method and grid search method. This paper also presents a new alarm system using the EEW information developed for a private railway. When this system will receive the EEW information and judge the earthquake to be dangerous for the railway by the M-Δ method, it will give the alarm to the running trains by train radio automatically. In this paper, we express a prospect for the real-time earthquake disaster prevention of railways.<br>"},{"@language":"ja","@value":"鉄道における地震災害を軽減するには事前に施設の耐震性を向上させることが基本であるが，一方で，地震発生時は迅速かつ適切に列車運行を制御することにより事故を未然に防ぐことが重要となる。そこで，鉄道総研では新幹線を中心に早期地震検知・警報システム（ユレダス）を開発，実用化してきた。しかし，近年では，リアルタイム地震学の分野の研究開発が進展し，早期地震警報に関する貴重な知見が蓄積されてきた。また，気象庁など公的機関の全国ネットの地震観測網が整備され，その即時情報（緊急地震速報という）を配信する計画が進められている。こうした状況を踏まえ，鉄道総研は気象庁と共同して，緊急地震速報の処理手法やこの情報を活用した鉄道の早期地震警報システムの開発を行ってきた。<br> 本論では，まず，P波初動検知後数秒で震源の位置やマグニチュードを推定するために新たに開発した，B-Δ法やテリトリー法，グリッドサーチ法について紹介する。次に，緊急地震速報を活用した地震警報システムの概要を紹介する。このシステムは緊急地震速報を受信すると，線区沿線での地震の影響度合いをM-Δ法により推定し，影響があると判断した場合は，列車無線により自動的に走行中の列車に緊急停止の警報を発信するものである。また，最後に，鉄道におけるリアルタイム地震防災の今後の展望について述べる。<br>"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410001205349344384","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000003808316"}],"foaf:name":[{"@language":"en","@value":"Ashiya
