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 65% likelyhood of between 0 and 1 fatalities, and a 96% chance that the number of fatalities falls no higher than 10.

The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 87% likelyhood of between 0 and 1 million US Dollars in economic damage and impact, and a 99% chance that the economic impact of this earthquake falls no higher than 10 million USD.

Roughly 17 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 17 million have been exposed to shaking at an MMI level of II or higher.

Very strong shaking and likely moderate damage may have been experienced by an estimated 4,890 people. At VII, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 12 million). In their region, weak shaking and probably 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 . Located 41 kilometer (25 mi) north-east of the epicenter of this earthquake, Anamizu (Ishikawa, Japan) is the nearest significant population center. Anamizu experienced an earthquake intensity (MMI Scale) of roughly V. That level implies moderate shaking and very light damage.

Major cities near this earthquake: Tokyo is located 291 km to the south-east (intensity unknown, possibly low). Nagoya is located 254 km to the south (intensity unknown, possibly low). Niigata is located 160 km to the east-northeast and experienced an intensity of IV (light shaking, likely no damage).

A complete list of nearby places is included below. Estimated intensity data (MMI) sourced from a shake-map published by the US Geographic Survey is shown where available (cities without data probably experienced little impact).

2 Aftershocks detected

Since this main shock, 2 smaller aftershocks were detected. A 4.9 magnitude earthquake hit 9 mins later 8 km (5 mi) north-east of this earthquake.

In the days before this main shock, 1 smaller foreshock was detected. Roughly 1 day before this earthquake, a foreshock measuring MAG-4.2 was detected nearby this earthquake.

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 January 9th, 2024, when a 5.9 magnitude earthquake hit 64 km (40 mi) further north-east. An even stronger magnitude 7.5 earthquake struck on January 1st, 2024.

In total, 9 earthquakes with a magnitude of 5.7 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.

Tsunami very unlikely

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.

While MAG-6.5+ earthquakes may cause tsunami's, it appears that the epicenter of this earthquake hit under land. In addition, the reported depth is deeper than 100km, making the risk of a tsunami even less likely. However always stay cautious and monitor advice from local authorities.

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 on land near a coastal area (1 km from the sea). Not this earthquake.
This earthquake had a magnitude of 5.7. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 9 km (6 mi). Earthquakes this shallow could trigger a tsunami.
