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 90% likelyhood of between 0 and 1 fatalities.
The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 90% likelyhood of between 0 and 1 million US Dollars in economic damage and impact.
Roughly 210 thousand people exposed to shaking
An estimated 210 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 II, which corresponds with very weak shaking and no damage. Roughly 212,200 people are expected to be exposed to this level. All exposure to shaking was within the borders of Russia .

Nearby towns and cities
This earthquake may have been felt in Russia . Located 87 kilometer (54 mi) south-east of the epicenter of this earthquake, Kavalerovo (Primorskiy (Maritime) Kray, Russia) is the nearest significant population center. The intensity of shaking and damage in Kavalerovo is estimated to be around level II on the Modified Mercalli Intensity scale (very weak shaking, no 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.

Earthquake Intensity Map
The maximum intensity (MMI Scale) caused by this earthquake is III. The map below shows in which areas this earthquake was the most and least impactful. It is based on data from the US Geographic Survey.
Risk of aftershocks?
This earthquake did not have any significant foreshocks nor aftershocks occurring within 100km (62 mi) of its epicenter.
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 of this strength are not so common in the region, but it's not the first time. This is the strongest earthquake to hit since June 27th, 2023, when a 5.8 magnitude earthquake hit 220 km (137 mi) further southwest. That was also the heaviest earthquake to hit the region in the past 10 years.
In total, 1 earthquake 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 10 years.
Tsunami very unlikely
For a serious tsunami to occur, earthquakes usually need to have a magnitude of at least 6.5 and occur at a shallow depth of maximum 100km. Neither are the case with this earthquake. 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 under the sea. | Not this earthquake. This earthquake had a magnitude of 5.7. Earthquakes of this strength are unlikely to trigger a tsunami. |
Not this earthquake. This earthquake occurred at a depth of 343 km (213 mi). Earthquakes this deep in the earth are unlikely to trigger a tsunami. |
