Earthquake Summary

The earthquake struck on land in The United States, 88 miles (142 km) southwest of Anchorage in Alaska. The center of this earthquake had a quite shallow depth of 34 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

Magnitude:	MAG 4.9 Detected by 68 stations. Maximum Error Range ±0.053 .
Depth:	34 mi (55 km) A quite shallow depth.
Max. Intensity:	V Moderate On the Modified Mercalli Scale.
Tsunami Risk:	Tsunami very unlikely While this was a shallow earthquake in a coastal area, it appears to have occurred under land (7 mi from the sea) with a magnitude that is usually not strong enough to cause tsunami's. Always stay cautious - More info here.

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 95% 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 450 thousand people exposed to shaking

An estimated 450 thousand have been exposed to shaking (An MMI or Modified Mercalli Intensity level II or higher) as a result of this earthquake according scientific estimates published by the USGS.

Light shaking and likely no damage may have been experienced by an estimated 2,360 people. At IV, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 240 thousand). In their region, weak shaking and probably no damage can be expected.

People	MMI Level	Shaking	Damage
28,770	I	Not noticable	None
201,400	II	Very weak	None
242,500	III	Weak	Probably none
2,360	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 . Anchorage in Alaska, The United States is the nearest significant place from the epicenter. The earthquake occurred 88 miles (142 km) southwest of Anchorage. Anchorage experienced an earthquake intensity (MMI Scale) of roughly II. That level implies very weak shaking and no damage.

Aftershocks detected

Since this main shock, 1 smaller aftershock was detected. A 3.2 magnitude earthquake hit 6 hrs later 57 mi (92 km) southwest of this earthquake.

In the days before this main shock, 1 smaller foreshock was detected. A 2.6 magnitude earthquake hit 2 days earlier nearby.

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 2.6	2 days earlier Jun 24, 2026 07:16PM (Anchorage Time)	25 mi (41 km) W from Main Shock.
Main Shock This Earthquake	M 4.9	Jun 26, 2026 05:15PM (Anchorage Time)	-
Aftershock	M 3.2	6 hrs later Jun 26, 2026 11:44PM (Anchorage Time)	57 mi (92 km) SW 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 101 mi (163 km) further north. An even stronger magnitude 7.1 earthquake struck on November 30th, 2018.

In total, 36 earthquakes with a magnitude of 4.9 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 3 months.

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 (7 mi from the sea).	Not this earthquake. This earthquake had a magnitude of 4.9. Earthquakes of this strength are unlikely to trigger a tsunami.	This earthquake occurred at a depth of of 34 mi (55 km). Earthquakes this shallow could trigger a tsunami.
