Earthquake Summary

This earthquake hit under water in the North Pacific Ocean, 46 kilometers (28 mi) off the coast of Japan, 52 kilometer south-east of Kamaishi in Iwate. The center of this earthquake had a quite shallow depth of 44 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

Potential Tsunami Risk

DISCLAIMER: We strongly suggest to closely monitor advice from local authorities with regards to tsunami risks. Our analysis is based on automatically collected data from external sources, and these might contain mistakes. In addition, earthquakes can cause landslides that may lead to a tsunami, or be a followed by another, potentially stonger, earthquake.

There is a potential tsunami risk in the aftermath of this earthquake, immediately evacuate to higher grounds away from coastal areas and monitor advice from local authorities. This earthquake checks all the likely tsunami risk factors: under sea, at a magnitude of MAG-6.5+ and at a shallow depth.

Tsunami Risk Factors

Factor Under Sea? MAG-6.5 or stronger? Shallow depth?
Explanation Almost all tsunami's are caused by earthquakes with their epicenter under sea or very near the sea. However stay cautious in coastal areas as earthquakes on land may cause landslides into sea, potentially still causing a local tsunami. Under MAG 6.5: Very unlikely to cause a tsunami.
MAG 6.5 to 7.5: Destructive tsunami's do occur, but are uncommon. Likely to observe small sea level changes.
MAG 7.6+: Earthquakes with these magnitudes might produce destructive tsunami's.
Most destructive tsunami's are caused by shallow earthquakes with a depth between 0 and 100km under the surface of the earth. Deeper tsunami's are unlikely to displace to ocean floor.
This Earthquake This earthquake appears to have struck under the sea. This earthquake had a magnitude of 6.7. Earthquakes of this strength could trigger a tsunami. This earthquake occurred at a depth of of 44 km (27 mi). Earthquakes this shallow could trigger a tsunami.

Minimal impact predicted

Based on scientific estimates by the US Geographic Survey (USGS), the risk of high fatalities for this earthquake is classified at level GREEN (low). They expect an 90% likelyhood of between 0 and 1 fatalities.

The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 90% likelyhood of between 0 and 1 million US Dollars in economic damage and impact.

Roughly 7 million people exposed to shaking

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 7 million have been exposed to shaking at an MMI level of II or higher.

The highest earthquake impact level for this earthquake is VI, which corresponds with strong shaking and probably light damage. Roughly 660 people are expected to be exposed to this level. Intensity level IV was experienced by the majority of people (around 6 million). In their region, light shaking and likely no damage can be expected. All exposure to shaking was within the borders of Japan .

Nearby towns and cities

This earthquake may have been felt in Japan . The closest significant population center near the earthquake is Ōfunato in Iwate, Japan. Ōfunato is located 49 kilometer (30 mi) east of the epicenter. Ōfunato experienced an earthquake intensity (MMI Scale) of roughly VI. That level implies strong shaking and probably light damage.

Major cities near this earthquake: Tokyo is located 424 km to the southwest (intensity unknown, possibly low). Yokohama is located 450 km to the southwest (intensity unknown, possibly low). Sendai is located 140 km to the southwest and experienced an intensity of IV (light shaking, likely no damage).

An overview of nearby towns and cities is available in the overview below. If places don't have intensity data available, it likely means the experienced impact in those places was fairly small.

More earthquakes coming?

Aftershocks are usually at least 1 order of magnitude less strong than main shocks. The more time passes, the smaller the chance and likely strength of any potential aftershocks.

The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this risk

Earthquakes like this are common in the region

Earthquakes of this strength occur quite regularly in the region. This is the strongest earthquake to hit since April 20th, 2026, when a 7.4 magnitude earthquake hit 136 km (85 mi) further north-east. An even stronger magnitude 7.6 earthquake struck on December 8th, 2025.

In total, 8 earthquakes with a magnitude of 6.7 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every year.
