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 Not this earthquake.
This earthquake appears to have struck on land far from any coast.
Not this earthquake.
This earthquake had a magnitude of 6. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 43 mi (69 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 470 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 470 thousand 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 0 people are expected to be exposed to this level. Intensity level IV was experienced by the majority of people (around 240 thousand). In their region, light shaking and likely no damage can be expected.

Nearby towns and cities

This earthquake may have been felt in The United States . Located 37 miles (60 km) northwest of the epicenter of this earthquake, Anchorage (Alaska, The United States) is the nearest significant population center. Anchorage experienced an earthquake intensity (MMI Scale) of roughly V. That level implies moderate shaking and very light 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.

9 Aftershocks detected

After this earthquake struck, 9 smaller aftershocks occurred. At a distance of 61 mi (98 km) north of this earthquake, an aftershock struck 12 hrs later. It measured a magnitude of 3.4

Before this earthquake struck, 3 smaller foreshocks occurred. Roughly 2 days before this earthquake, a foreshock measuring MAG-3 was detected nearby this earthquake.

More earthquakes coming?

Earthquakes can create aftershocks. These are generally at least 1 magnitude lower than any main shock, and as time passes the chance and strength of aftershocks decreases.

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.

This is the strongest earthquake in 4 years

Earthquakes of this strength occur quite regularly in the region. This is the strongest earthquake to hit since May 31st, 2021, when a 6.1 magnitude earthquake hit 101 mi (163 km) further north-east. An even stronger magnitude 7.1 earthquake struck on November 30th, 2018.

In total, 3 earthquakes with a magnitude of 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 3 years.
