Ten years of larger earthquakes in and around Japan, from Kumamoto to Noto to the sea off Aomori. Where they began, how deep they were, and how Japan changed the way it warns people about the next one.

The report

The bigger quake came second.

At 9:26 p.m. on April 14, 2016, a magnitude 6.2 earthquake struck beneath Kumamoto. Twenty-eight hours later, at 1:25 a.m. on April 16, a magnitude 7.0 hit the same area. The first quake had not been the main one. USGS event record.

This atlas maps 289 earthquakes of magnitude 5.5 or greater in and around Japan between 2016 and 2025. Of those, 7 reached magnitude 7: Kumamoto in 2016, three off Fukushima and Miyagi in 2021 and 2022, Noto on New Year’s Day 2024, Hyūga-nada in August 2024 and the largest, a 7.6 off Aomori in December 2025. The yearly count ranged from 18 in 2019 to 40 in 2016 and 2023.

Each dot marks an epicenter: the point on the surface above where the rupture began. It does not show how far the shaking reached or where it was strongest. Offshore events are included but are not assigned to a prefecture. The 2011 Tohoku earthquake falls before this window.

Why Japan stopped saying “aftershock”

Kumamoto changed the vocabulary. The word “aftershock” implied that nothing bigger would follow, and in Kumamoto something bigger did. In August 2016 the government’s earthquake research body recommended dropping it from public warnings. After a large quake, the Japan Meteorological Agency now tells people to watch for another of similar size, usually for about a week. JMA.

Two warnings used for the first time

On August 8, 2024, a magnitude 7.1 earthquake struck off Miyazaki in the Hyūga-nada, at the western end of the Nankai Trough. That evening JMA issued its first Nankai Trough megaquake advisory, a system in place since 2019. It said the chance of a very large earthquake along the trough was higher than usual and asked people to check their preparations for about a week. JMA, August 2024.

On December 8, 2025, a magnitude 7.5 on JMA’s scale (7.6 in the USGS catalog) struck off Aomori and shook Hachinohe at intensity 6 upper. A few hours later JMA issued its first Hokkaido–Sanriku subsequent-earthquake advisory, a warning introduced in 2022. Neither advisory is a prediction. Each says that the odds have gone up for a while. JMA, December 2025.

Reading the data

Depth changes the picture.

Most of these earthquakes were shallow: 236 of 289 began less than 70 km down. Another 23 were 70 to 300 km deep, and 30 were deeper than 300 km. The deepest, 585 km down with magnitude 5.8, began beneath northeast China, northwest of the Sea of Japan. USGS record.

Filter the depth bands and the map changes shape. The colors are a way to read the catalog, not a scale of danger: depth is one part of an earthquake’s description, and the map does not calculate shaking at any location.

Magnitude describes the size of an earthquake. Seismic intensity describes the shaking at a particular place, and Japan measures it on its own 0–7 scale. The same earthquake produces different intensities in different towns and even different buildings, so a magnitude cannot tell you what people felt. JMA seismic intensity scale.

After the map ends

This snapshot stops at the end of 2025, so it does not show the Kumamoto earthquake of July 28, 2026. That magnitude 7.1 struck about 15 km down along the Hinagu fault zone, just southwest of the area that shook in 2016, and reached the top of the intensity scale, 7. The government’s Earthquake Research Committee had already rated the chance of an earthquake on that part of the fault within 30 years as high, and it noted that seismic activity in the region had stayed elevated since 2016. Earthquake Research Committee, July 2026.

Historical context

Limits for travel planning.

The quiet parts of a ten-year map are not certified safe zones. Aftershock sequences produce clusters, and a count of past events is not a forecast of the next one. USGS magnitudes can also differ from those published by JMA, which is why the atlas shows each record’s magnitude type.

We do not rank prefectures by “earthquake safety,” infer current tsunami conditions, or recommend routes from these dots.

For an ongoing event, use the Japan Meteorological Agency’s current earthquake and tsunami information and follow local instructions. The link below is live and separate from this saved dataset. JMA current earthquake information.

  1. Source: USGS ANSS Comprehensive Earthquake Catalog (ComCat), event type earthquake, minimum preferred magnitude 5.5. Time limits are 2016-01-01 00:00:00 UTC through 2025-12-31 23:59:59.999 UTC.
  2. Geographic selection: 24–46°N and 122–146°E. This rectangle includes parts of neighboring territories; it is not a Japanese national boundary or a claim that every event occurred in Japan.
  3. The query returned 289 events, below its 20,000-record limit. Re-running it on September 24, 2026 returned the same 289 events with identical magnitudes, depths and coordinates. The saved data retains event IDs, UTC times, magnitudes, magnitude types, depths, coordinates and USGS links. Later catalog revisions may change a repeated query.
  4. Map geometry uses a fixed equirectangular projection with no island insets; only Japanese land outlines are drawn. Colors show depth classes, circle radius increases with magnitude, and radius is not proportional to energy released.
  5. No hazard model, shaking-intensity estimate, damage estimate or tsunami forecast is computed.
