In the evening of Friday June 19th, 2026, a shallow and strong Magnitude 6.6 earthquake hit in the North Pacific Ocean 133 kilometer from Petropavlovsk-Kamchatsky, Russia. Mag 6.5+ earthquakes at shallow depth under sea have the potential to cause tsunami's.

Earthquake Summary

This earthquake hit under water in the North Pacific Ocean, 66 kilometers (41 mi) off the coast of Russia, 133 kilometer east of Petropavlovsk-Kamchatsky in Kamchatka. The center of this earthquake had a very shallow depth of 10 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

Potential 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.

There is a potential tsunami risk in the aftermath of this earthquake, immediately evacuate to higher grounds away from coastal areas and monitor advice from local authorities. This earthquake checks all the likely tsunami risk factors: under sea, at a magnitude of MAG-6.5+ and at a shallow depth.

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.	This earthquake had a magnitude of 6.6. Earthquakes of this strength could trigger a tsunami.	This earthquake occurred at a depth of of 10 km (6 mi). Earthquakes this shallow could trigger a tsunami.

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 260 thousand people exposed to shaking

This earthquake may have been felt by around 260 thousand people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.

An estimated 130 people were exposed to level V. At this level, moderate shaking and very light damage can be expected. The majority of people (roughly 260 thousand) live in an area exposed to level IV, where light shaking and likely no damage is expected. All exposure to shaking was within the borders of Russia .

People	MMI Level	Shaking	Damage
0	I	Not noticable	None
0	II	Very weak	None
730	III	Weak	Probably none
255,600	IV	Light	Likely none
130	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

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 133 kilometer (83 mi) east of the epicenter. The intensity of shaking and damage in Petropavlovsk-Kamchatsky is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).

8 Aftershocks detected

After this earthquake struck, 8 smaller aftershocks occurred. At a distance of 38 km (23 mi) east of this earthquake, an aftershock struck 1 hr later. It measured a magnitude of 5.8

This main shock was prefaced by 2 smaller foreshocks. Roughly 1 min before this earthquake, a foreshock measuring MAG-6 was detected nearby this earthquake.

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?

Earthquakes can create aftershocks. These are generally at least 1 magnitude lower than any main shock, and as time passes the chance and strength of aftershocks decreases.

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 are common in the region

Earthquakes of this strength occur quite regularly in the region. This is the strongest earthquake to hit since September 18th, 2025, when a 7.8 magnitude earthquake hit 40 km (25 mi) further north. An even stronger magnitude 8.8 earthquake struck on July 29th, 2025.

In total, 6 earthquakes with a magnitude of 6.6 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 2 years.
