Earthquake Summary

The earthquake struck on land in The United States, 59 miles (95 km) northwest of Anchorage in Alaska. The center of this earthquake had a very shallow depth of 9 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

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 69% likelyhood of between 0 and 1 fatalities, and a 98% 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 65% likelyhood of between 0 and 1 million US Dollars in economic damage and impact, and a 96% chance that the economic impact of this earthquake falls no higher than 10 million USD.

Roughly 410 thousand people exposed to shaking

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 410 thousand have been exposed to shaking at an MMI level of II or higher.

Light shaking and likely no damage may have been experienced by an estimated 10 people. At IV, it is the highest MMI level this earthquake has caused. The majority of people (roughly 350 thousand) live in an area exposed to level III, where weak shaking and probably no damage is expected.

Nearby towns and cities

This earthquake may have been felt in The United States . Located 59 miles (95 km) northwest of the epicenter of this earthquake, Anchorage (Alaska, The United States) is the nearest significant population center. The intensity of shaking and damage in Anchorage is estimated to be around level III on the Modified Mercalli Intensity scale (weak shaking, probably no damage).

5 Aftershocks detected

Since this main shock, 5 smaller aftershocks were detected. At a distance of 59 mi (95 km) south of this earthquake, an aftershock struck 4 hrs later. It measured a magnitude of 3.5

Before this earthquake struck, 2 smaller foreshocks occurred. A 3 magnitude earthquake hit 1 hr earlier nearby.

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.

It's always adviced to be cautious of the risk of a larger shock following any significant earthquake, however this risk is fairly small. There is a roughly 94 percent change that no larger main shock will follow in the days following this earthquake.

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since April 29th, 2025, when a 4.7 magnitude earthquake hit 87 mi (139 km) further south-southeast. An even stronger magnitude 7.1 earthquake struck on November 30th, 2018.

In total, 210 earthquakes with a magnitude of 4.1 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 17 days.

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 Not this earthquake.
This earthquake appears to have struck on land far from any coast.
Not this earthquake.
This earthquake had a magnitude of 4.1. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 9 mi (15 km). Earthquakes this shallow could trigger a tsunami.
