Intensity 7 (震度7, Shindo-nana) is the highest level on the JMA seismic intensity scale, applied to earthquakes with an instrumental intensity (計測震度) of 6.5 or higher. [6] At Intensity 7, movement becomes nearly impossible without external support. [ 11 ]

This earthquake occurred on Dec. 7, 1944, at 13:35 local time (04:35 UTC). Its moment magnitude was 8.1 and it was felt with a maximum intensity of 5 on the Shindo scale (or VII, "Severe", on the Mercalli intensity scale). It struck the provinces along the coast of the Tōkai region, causing serious damage and triggering a tsunami.
Japan had experienced 900 aftershocks after the M9.1 earthquake on March 11, 2011 with about 60 aftershocks being over magnitude 6.0 and three over magnitude 7.0. For conciseness, only earthquakes with magnitudes greater than 7.0 or an intensity greater than lower-6 on the shindo scale are listed here.
The United States typically has around 63 earthquakes between magnitude 5.0 and 5.9 each year, according to the U.S. Geological Survey, about five between 6.0 and 6.9 and fewer than one between 7. ...
It was the first time that an earthquake in Japan was officially measured at a seismic intensity (shindo in Japanese) of the highest Level 7 on the scale of Japan Meteorological Agency (JMA). After the earthquake, seismic intensity observation in Japan was fully mechanized (from April 1996) and JMA seismic intensity Levels 5 and 6 were each ...
The Japan Meteorological Agency said it recorded a maximum seismic intensity of 7 (Shindo 7), the highest level on its seismic intensity scale, [49] the first time that an earthquake of that intensity had been observed in the country since 2018. [50] [51] It corresponded to a maximum Modified Mercalli intensity of X–XI (Extreme). [15]
A 7.0 magnitude earthquake was reported off the coast of Northern California on Thursday, according to the United States Geological Survey. ... and a 34% chance of a magnitude 5 quake occurring in ...
