Questions
How many earthquakes happen in Japan?
In the last 30 days, 171 earthquakes of magnitude 2.5 or greater were recorded in Japan, 40 of them in the last 7 days. In the last 24 hours, 6 earthquakes of any magnitude were recorded. Most small earthquakes are not felt.
What was the largest recent earthquake in Japan?
The largest in the last 30 days was a magnitude 5.1 earthquake 122 km S of Koseda, Kagoshima, Japan on 12 Sep 2026, at a depth of 30 km.
What is the largest earthquake recorded in Japan since 1900?
According to the USGS catalogue, the largest was a magnitude 9.1 earthquake on 11 Mar 2011 (2011 Great Tohoku Earthquake, Japan). Magnitudes of early 20th-century earthquakes are less certain than modern ones.
How deep are earthquakes in Japan?
94% of the magnitude 2.5+ earthquakes recorded in Japan in the last 30 days were shallower than 70 km. Shallow earthquakes generally cause stronger shaking at the surface than deep ones of the same magnitude.
Where can I get official earthquake information for Japan?
For official information, warnings and safety advice, follow Japan Meteorological Agency (https://www.jma.go.jp/jma/indexe.html) and your local civil protection authority. This site compiles agency reports and is not a warning service.
Can earthquakes be predicted?
No. Scientists can estimate how likely strong shaking is in a region over years or decades, but no method predicts the time, place and size of a specific earthquake. Aftershocks are expected after large earthquakes and become less frequent over time.
