Intensity 7 (震度7, Shindo-nana) is the highest level on the JMA seismic intensity scale. At Intensity 7, movement at will is almost impossible, and people may be thrown through the air. [3] The intensity was created following the 1948 Fukui earthquake. It was observed for the first time in the 1995 Great Hanshin earthquake.

The Japan Meteorological Agency said it recorded a maximum seismic intensity of 7 (Shindo 7), the highest level on its seismic intensity scale, [51] the first time that an earthquake of that intensity had been observed in the country since 2018. [52] [53] It corresponded to a maximum Modified Mercalli intensity of X–XI (Extreme). [17]
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 ...
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 earthquake was the first to have ever reached a maximum level of 7 on the Japan Meteorological Agency seismic intensity scale, or Shindo scale, in Hokkaido [28] and the sixth in Japan since the system was put in place in 1949. [citation needed]
The island's most powerful earthquake since Hawaii became a state was a magnitude 7.7 in 1975, with an epicenter about 27 miles southeast of Hilo. "And that was really devastating.
The magnitude 6.9 or 7.0 earthquake struck offshore east of Tōhoku, Japan at a depth of 54.0 kilometers (33.6 mi) to 60 kilometers (37 mi). [3] [4] It had a maximum JMA intensity of Shindo 5+ while on the Mercalli intensity scale, it earned a rating of VII (Very strong). [5] Power outages and some slight damage in Miyagi was reported. [6]
