M4.6 Earthquake hit near Anchorage in The United States on Tuesday Morning.

Written by Earthquakelist.org on February 10th, 2026.

Around noon of Tuesday February 10th, 2026, a Magnitude 4.6 earthquake hit under land 34 miles from Anchorage in The United States. The USGS has indicated there is a potential risk at tsunami's following this earthquake.

Earthquake Summary

The earthquake struck on land in The United States, 34 miles (55 km) north-northeast of Anchorage in Alaska. The center of this earthquake had a quite shallow depth of 19 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. The US Geographic Survey organization has indicated a potential risk for tsunami's following this earthquake.

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 (14 mi from the sea).	Not this earthquake. This earthquake had a magnitude of 4.6. Earthquakes of this strength are unlikely to trigger a tsunami.	This earthquake occurred at a depth of of 19 mi (30 km). 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 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 430 thousand people exposed to shaking

This earthquake may have been felt by around 430 thousand people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.

Weak shaking and probably no damage may have been experienced by an estimated 393,000 people. At III, it is the highest MMI level this earthquake has caused.

People	MMI Level	Shaking	Damage
48,130	I	Not noticable	None
34,090	II	Very weak	None
393,000	III	Weak	Probably none
0	IV	Light	Likely none
0	V	Moderate	Very light
0	VI	Strong	Light
0	VII	Very Strong	Moderate
0	VIII	Severe	Moderate to heavy
0	IX	Violent	Heavy
0	X	Extreme	Very heavy

Nearby towns and cities

This earthquake may have been felt in The United States . Located 26 miles (42 km) north of the epicenter of this earthquake, Eagle River (Alaska, The United States) is the nearest significant population center. The intensity of shaking and damage in Eagle River is estimated to be around level III on the Modified Mercalli Intensity scale (weak shaking, probably no damage).

Aftershocks detected

Since this main shock, 1 smaller aftershock was detected. A 3 magnitude earthquake hit 6 mins later 1.4 mi (2.2 km) west of this earthquake.

Before this earthquake struck, 1 smaller foreshock occurred. Nearby this earthquake a foreshock struck 1 day earlier. It measured a magnitude of 2.5

Overview of foreshocks and aftershocks

Detected MAG2.5+ earthquakes within within 100km (62 mi), that occurred in the three days before and after the main shock.
Classification	Magnitude	When	Where
Foreshock	M 2.5	1 day earlier Feb 9, 2026 02:45AM (Anchorage Time)	48 mi (78 km) SSE from Main Shock.
Main Shock This Earthquake	M 4.6	Feb 10, 2026 11:42AM (Anchorage Time)	-
Aftershock	M 3.0	6 mins later Feb 10, 2026 11:48AM (Anchorage Time)	1.4 mi (2.2 km) W from Main Shock.

More earthquakes coming?

The risk of aftershocks decreases rapidly over time. Usually, aftershocks are at least one order of magnitude lower than a main shock.

In only six percent of cases, significant earthquakes are followed by a larger main shock, making the current earthquake a foreshock. While the chance of this happening is not so large, it is adviced to maintain cautiousness in the hours and days following a major 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 November 27th, 2025, when a 6 magnitude earthquake hit 38 mi (61 km) further west-southwest. An even stronger magnitude 7.1 earthquake struck on November 30th, 2018.

In total, 65 earthquakes with a magnitude of 4.6 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 2 months.
