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.

The highest earthquake impact level for this earthquake is IV, which corresponds with light shaking and likely no damage. Roughly 280 people are expected to be exposed to this level. 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 .

People	MMI Level	Shaking	Damage
0	I	Not noticable	None
290	II	Very weak	None
265,800	III	Weak	Probably none
280	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 Vilyuchinsk in Kamchatka, Russia. Vilyuchinsk is located 127 kilometer (79 mi) south 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).

3 Aftershocks detected

After this earthquake struck, 3 smaller aftershocks occurred. A 4.6 magnitude earthquake hit 10 hrs later 88 km (54 mi) north-east of this earthquake.

Before this earthquake struck, 1 smaller foreshock occurred. A 4.3 magnitude earthquake hit 6 hrs 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 4.3	6 hrs earlier Nov 4, 2025 01:13 (Kamchatka Time)	93 km (58 mi) NE from Main Shock.
Main Shock This Earthquake	M 5.4	Nov 4, 2025 07:38 (Kamchatka Time)	-
Aftershock	M 4.6	10 hrs later Nov 4, 2025 17:20 (Kamchatka Time)	88 km (54 mi) NE from Main Shock.
Aftershock	M 4.5	10 hrs later Nov 4, 2025 17:33 (Kamchatka Time)	81 km (50 mi) NNE from Main Shock.
Aftershock	M 4.5	1 day later Nov 5, 2025 10:51 (Kamchatka Time)	81 km (50 mi) E from Main Shock.

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.

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 November 3rd, 2025, when a 6.1 magnitude earthquake hit 156 km (97 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

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 5.4. Earthquakes of this strength are unlikely to trigger a tsunami.	This earthquake occurred at a depth of of 74 km (46 mi). Earthquakes this shallow could trigger a tsunami.
