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

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 270 thousand have been exposed to shaking at an MMI level of II or higher.

An estimated 205,100 people were exposed to level IV. At this level, light shaking and likely no damage can be expected. All exposure to shaking was within the borders of Russia .

People	MMI Level	Shaking	Damage
0	I	Not noticable	None
220	II	Very weak	None
60,150	III	Weak	Probably none
205,100	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 Russia . The closest significant population center near the earthquake is Petropavlovsk-Kamchatsky in Kamchatka, Russia. Petropavlovsk-Kamchatsky is located 74 kilometer (46 mi) east-northeast of the epicenter. Petropavlovsk-Kamchatsky experienced an earthquake intensity (MMI Scale) of roughly IV. That level implies light shaking and likely no damage.

2 Aftershocks detected

After this earthquake struck, 2 smaller aftershocks occurred. At a distance of 78 km (49 mi) south-southwest of this earthquake, an aftershock struck 2 days later. It measured a magnitude of 4.5

Before this earthquake struck, 5 smaller foreshocks occurred. Nearby this earthquake a foreshock struck 2 days earlier. It measured a magnitude of 4.9

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.

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.

The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this risk

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 October 9th, 2025, when a 6.1 magnitude earthquake hit 201 km (125 mi) further south-southwest. An even stronger magnitude 8.8 earthquake struck on July 29th, 2025.

In total, 44 earthquakes with a magnitude of 5.7 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 (5 km from the sea).	Not this earthquake. This earthquake had a magnitude of 5.7. Earthquakes of this strength are unlikely to trigger a tsunami.	This earthquake occurred at a depth of of 75 km (47 mi). Earthquakes this shallow could trigger a tsunami.
