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 260 thousand people exposed to shaking

An estimated 260 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 0 people. At IV, it is the highest MMI level this earthquake has caused. The majority of people (roughly 240 thousand) live in an area exposed to level III, where weak shaking and probably no damage is 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 131 kilometer (81 mi) south-southeast of the epicenter. The intensity of shaking and damage in Vilyuchinsk is estimated to be around level III on the Modified Mercalli Intensity scale (weak shaking, probably no damage).

7 Aftershocks detected

This main shock was followed by 7 smaller aftershocks. A 4.9 magnitude earthquake hit 2 days later 12 km (8 mi) east of this earthquake.

Before this earthquake struck, 15 smaller foreshocks occurred. Nearby this earthquake a foreshock struck 5 sec earlier. It measured a magnitude of 5.3

Overview of foreshocks and aftershocks

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 November 4th, 2025, when a 6 magnitude earthquake hit 78 km (48 mi) further east-northeast. An even stronger magnitude 8.8 earthquake struck on July 29th, 2025.

In total, 145 earthquakes with a magnitude of 5.4 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 25 days.

Low tsunami risk

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.
