A note about the classification of earthquake depth: Shallow earthquakes are considered to have occurred when the depth is between 0-70km, intermediate earthquakes are between 70-300km, and deep earthquakes are between 300-700km.

Earthquakes (Japan)

Note: Japan utilises the Japanese Intensity Scale as well as magnitude. This scale has a maximum of 7, with + and - standing for "upper" and "lower" respectively. Intensity is not equivalent to magnitude. Magnitude refers to the total energy released at the source of the earthquake, while intensity refers to the amount of shaking experienced at any given location.

Due to the frequency of earthquakes in Japan, events less than Int. 3 are contained in a smaller list below. These lists are updated manually; do not rely on them for timely information on earthquakes or tsunamis. For this and early warnings, I recommend you use NERV.

Showing 50 earthquakes.
