Earthquake Summary

This earthquake hit under water in the North Pacific Ocean, 59 kilometers (37 mi) off the coast of Russia, 125 kilometer south of Petropavlovsk-Kamchatsky in Kamchatka. The center of this earthquake had a quite shallow depth of 42 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 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 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 270 thousand people exposed to shaking

An estimated 270 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.

An estimated 860 people were exposed to level IV. At this level, light shaking and likely no damage can be expected. Intensity level III was experienced by the majority of people (around 270 thousand). In their region, weak shaking and probably no damage can be expected. All exposure to shaking was within the borders of Russia .

Nearby towns and cities

This earthquake may have been felt in Russia . The closest significant population center near the earthquake is Vilyuchinsk in Kamchatka, Russia. Vilyuchinsk is located 115 kilometer (71 mi) south-southeast of the epicenter. Vilyuchinsk experienced an earthquake intensity (MMI Scale) of roughly IV. That level implies light shaking and likely no damage.

Aftershocks detected

In the days before this main shock, 1 smaller foreshock was detected. A 4.7 magnitude earthquake hit 1 day earlier nearby.

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.

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 September 1st, 2023, when a 6.1 magnitude earthquake hit 232 km (144 mi) further southwest. An even stronger magnitude 7.2 earthquake struck on January 30th, 2016.

In total, 7 earthquakes with a magnitude of 5.8 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.

Low 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.

Based on early data it appears this earthquake was not strong enough (lower than MAG-6.5) to be likely to cause destructive tsunami's. However this earthquake appeared to have hit at a shallow depth under sea, so 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 under the sea. Not this earthquake.
This earthquake had a magnitude of 5.8. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 42 km (26 mi). Earthquakes this shallow could trigger a tsunami.
