Quakelog has been kept since 13/05/2026.
Please note that Quakelog does contain some gaps in the latter half of 2026, due to technical limitations at time of capture (usually only a few days each). I am working on building a more robust information capture system so that there are no gaps in 2027.
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.
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.

Area Breakdown
This is such a weird earthquake to look at the spread map of. It originated in Gifu in Chuubu, which is much closer to Osaka than it is to Tokyo, and yet the only places it was felt were up north in Kanto and Tohoku. I suppose it has something to do with the depth?
