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.The JMA uses seismic intensity meters to automatically calculate peak ground acceleration in real-time, reporting intensities based on measurements from observation points.
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 Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth.
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]

UTC−08:00 – Pacific Time zone: the Pacific coast states, the Idaho Panhandle and most of Nevada and Oregon UTC−07:00 – Mountain Time zone: most of Idaho, part of Oregon, and the Mountain states plus western parts of some adjacent states UTC−06:00 – Central Time zone: a large area spanning from the Gulf Coast to the Great Lakes
At this location, the Pacific plate moves approximately westward relative to the North American plate at a velocity of 70 mm (2.8 in)/yr, subducting beneath Japan at the Japan Trench. This subduction zone is capable of producing megathrust earthquakes with magnitudes greater than 8.5, evident in the historical records.
