Earthquake Summary
This earthquake hit under water in the North Pacific Ocean, 58 kilometers (36 mi) off the coast of Russia, 223 kilometer south of Petropavlovsk-Kamchatsky in Kamchatka. The center of this earthquake had a quite shallow depth of 55 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

2 Aftershocks detected
This main shock was followed by 2 smaller aftershocks. Just 18 hrs after this main shock, an earthquake measuring MAG-4.5 was detected 88 km (55 mi) southwest of this earthquake.
This main shock was prefaced by 1 smaller foreshock. A 4.1 magnitude earthquake hit 2 days earlier nearby.

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 of this strength are very common in the region. This is the strongest earthquake to hit since October 11th, 2025, when a 5.8 magnitude earthquake hit 129 km (80 mi) further southwest. An even stronger magnitude 8.8 earthquake struck on July 29th, 2025.
In total, 290 earthquakes with a magnitude of 5.1 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 13 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.
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 5.1. Earthquakes of this strength are unlikely to trigger a tsunami. |
This earthquake occurred at a depth of of 55 km (34 mi). Earthquakes this shallow could trigger a tsunami. |
