The most recent similar-sized comparable to the 2021 quake was the 6.9 M w 2016 Fukushima earthquake, which occurred just southwest of where the February 2021 earthquake struck. That earthquake was the result of normal faulting within the overriding Okhotsk Sea Plate at a depth of 9 km (5.6 mi). [ 22 ]
The earthquake had a depth of 47.3 km or 66 km and a maximum intensity of VI (Strong) or Shindo 5 upper. [30] According to the Japan Meteorological Survey, the earthquake would not be considered an aftershock of the 2011 Great East Japan earthquake as such announcements had ceased as of April 1 of 2021.

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 ...
