The Japan Meteorological Agency (JMA) Seismic Intensity Scale [1] (known in Japan as the Shindo seismic scale) [2] is a seismic intensity scale used in Japan to categorize the intensity of local ground shaking caused by earthquakes.

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, the Liedu scale used in China or the European Macroseismic Scale (EMS), meaning that the scale measures the intensity of an earthquake at a given location instead of measuring the energy an earthquake ...
On January 13, 2025, at 9:19pm JST, a 6.9 M JMA earthquake struck less than 10 km (6.2 mi) away from the August 8, 2024 earthquake at a depth of 30 km (19 mi), causing tremors recorded as a 5- on the JMA seismic intensity scale [15] and an observed 20cm tsunami in Miyazaki Prefecture.
A large earthquake shook Kyushu, Japan, just after 9 p.m. local time Monday night, triggering a tsunami advisory for Japan's southeast coast. The quake was centered just offshore of Kyushu, about ...
This map shows the epicenter of a 7.0 earthquake off the coast of Japan late Saturday afternoon, local time, and the areas estimated to have felt shaking. (USGS) At least two injuries has been ...

In Japan, for shallow (depth < 60 km) earthquakes within 600 km, the Japanese Meteorological Agency calculates [2] a magnitude labeled MJMA, M JMA, or M J. (These should not be confused with moment magnitudes JMA calculates, which are labeled M w (JMA) or M (JMA), nor with the Shindo intensity scale.)
The earthquake struck at 4:10 p.m. local time at a depth of 10 kilometers (6 miles) in the Noto Peninsula of Ishikawa prefecture, according to the United States Geological Survey (USGS).
