Japan’s Meteorological Agency warns major quakes could hit the area over the next week Japan earthquake – latest: Aftershocks continue in quake zone as death toll rises to 64 Skip to main content
A series of powerful earthquakes that hit western Japan left at least 62 people dead Wednesday, as rescue workers fought to save those feared trapped under the rubble of collapsed buildings.
Following the earthquake, the Japan Meteorological Agency (JMA) issued a 'Nankai Trough Earthquake Extra Information' advisory [23] that the probability of a megathrust earthquake along the Nankai Trough increased from a 0.1% per week to 1% chance [24] in what was the first advisory of its kind but clarified that it was not imminent.
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.
Those buildings were believed to be largely unoccupied when, according to the Japan Meteorological Agency, the quakes hit off the Ishikawa coast a little after 4 p.m. local time (2 a.m. ET), with ...
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 or the Liedu scale used in China, meaning that the scale measures the intensity of an earthquake at a given location instead of measuring the energy an earthquake releases at its epicenter (its magnitude ...
The Japan Meteorological Agency warned the citizens of Ishikawa that strong aftershocks could occur for at least a week. The mayor of Suzu, issuing an earthquake emergency advisory and evacuating multiple households, said that the city would not be needing the help of Japan Self-Defense Forces due to the quake. [27]
