Japan issued a “megaquake advisory” following a 7.1-magnitude earthquake off its coast. That raised the risk of a larger quake on the Nankai Trough, an underwater subduction zone.
The most devastating recorded natural disaster to affect Japan by death toll was the 1923 Great Kantō earthquake, which killed ~105,000 and a further ~6,000 due to the Kantō Massacre in its immediate aftermath. Japan has also been the site of some of the 10 worst natural disasters of the 21st century.
Japan, one of the most earthquake-prone nations on earth, issued its first-ever “megaquake advisory” last week after a powerful quake struck off the southeastern coast of the southern main ...
The JMA announced the Earthquake Early Warning hit (accuracy) rate for the 2011 fiscal year on 31 May 2012. The hit rate is the percentage of warnings issued immediately on the detection of P-waves with a Japan Meteorological Agency seismic intensity scale (震度, shindo) number (0 to 7) within one shindo number of the measured earthquake.
Seismic observations in Japan began in 1872. In 1884, Sekiya Seikei, Director of the Earthquake Division under the Home Ministry, compiled the 18-article "Earthquake Report Guidelines" and initiated data collection from 600 county offices nationwide. This was Japan’s first unified seismic intensity scale.
A large earthquake shook Kyushu, Japan, just after 9 p.m. local time Monday night, triggering a tsunami advisory for Japan's southeast coast. The quake was centered just offshore of Kyushu, about ...
In Japan, the Shindo scale is commonly used to measure earthquakes by seismic intensity instead of magnitude. This is similar to the Modified Mercalli intensity scale used in the United States, the Liedu scale used in China or the European Macroseismic Scale (EMS), meaning that the scale measures the intensity of an earthquake at a given location instead of measuring the energy an earthquake ...
Multiple notable earthquakes have struck the United States this year, including a powerful quake in California and a historic event on the East Coast earlier in 2024. Strong earthquakes can lead ...
