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 area is associated with large earthquakes in 1662 (M w 7.9), 1941 (M w 8.0), 1961 (M w 7.5), [3] 1968 (M w 7.5) and two in 1996 (M w 6.6 [4] and 6.7 [5]). The Hyūga Sea is interpreted as a transition zone between the highly coupled Nankai Trough in the northeast and weakly coupled Ryukyu Trench further southwest. [ 6 ]
The JMA scale is expressed in levels of seismic intensity from 0 to 7 in a manner similar to that of the Mercalli intensity scale, which is not commonly used in Japan.. Real-time earthquake reports are calculated automatically from seismic-intensity-meter measurements of peak ground acceleration throughout an affected area, and the JMA reports the intensities for a given quake according to the ...

The 2021 Chiba earthquake (千葉県北西部地震, Chiba-ken Hokuseibu Jishin) was an earthquake that occurred in Japan at 22:41 JST (13:41 UTC) on October 7, 2021. [2] The epicenter was recorded approximately 4 kilometers (2.5 mi) southwest of Chiba in Chiba Prefecture.
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 ]
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.
The largest of the islands, Honshu is characterised by numerous inland fault systems and large subduction zones which are a result of the interaction between several tectonic plates. [9] At the junction of the continental Okhotsk microplate and the oceanic Philippine Sea and Pacific plates lies the populous Kantō Region , which has had a long ...
