In February 2007, Japan’s Fire and Disaster Management Agency (FDMA) launched J-Alert, an early warning system that transmits instant emergency information about threats such as earthquakes, tsunamis and ballistic missile via sirens, so that people can respond immediately. News. Japan is one of the most well-prepared countries in the world to deal with the threat of a tsunami.Warning systems are in place, and concrete sea walls wrap around much of the coastline. The Japan Meteorological Agency issued a special heavy rain warning to Miyakejima and Mikurajima, part of the island chain. Japan is situated in one of the most active areas in the world, where the Pacific and Philippine Sea Plates are subducting the Eurasian Plate and where stress and strain of the crust are accumulated (Fig. At the time of the 2011 Tohoku-oki earthquake and tsunami (also known as 3.11), several million people near the epicenter received the EEW about 15 to 20 seconds before the most severe … Earthquake Early Warning System in Japan. The first information given is based on the earthquake’s location and magnitude and on a large database of computer simulation, using several tsunamis with earthquakes scenarios in different locations and with different magnitudes. Generally, if an earthquake is strong enough to cause a violent movement of the earth with a sudden displacement of the ocean water, you can expect to observe a tsunami. Japan’s much vaunted J-Alert warning system running up against its limitations. JMA also issues information on tsunami details such as estimated arrival times and heights. Šæ€¥åœ°éœ‡é€Ÿå ±) is managed by the Japan Meteorological Agency (JMA; 気象庁), and was first launched on October 1st, 2007 (JMA, 2007b).

"The system in Japan is very well attuned to earthquakes and tsunamis. Windshear is a drastic, sudden change in wind direction or speed over a relatively short distance in the atmosphere. Problems of the present EEW system (1) Sometimes EEW is issued after S -wave arrival (3) False alarm Warning times become negative within an area about 30km from the epicenter. When windshear is predicted or when the aircraft has encountered windshear, the system alerts the pilot and warns of danger. In this early state, since the JMA doesn’t have yet all the necessary information about the tsunami, it is important not to underestimate the tsunami heights so that people realize the real danger, and also because communications might be cut, and people won’t be able to get the tsunami update after the first warning. Japan is well-known for its major natural disasters, like the Great East Japan Earthquake in 2011 that resulted in a huge tsunami creating terrible consequences. ), Monitoring of Earthquakes, Tsunamis & Volcanic Activity, Flow of issuance of information about tsunami and earthquake, Explanation about Tsunami Warning/Advisory and Tsunami Information, Lessons learned from the tsunami disaster caused by the 2011 Great East Japan Earthquake and improvements in JMA's tsunami warning system, Start of New Tsunami Warning System Operation.
