Shallow M6.6 earthquake hits near Petropavlovsk-Kamchatsky, Russia on June 19, 2026

A shallow M6.6 earthquake was registered at 06:52 UTC on June 19, 2026, approximately 136 km (85 miles) east of Petropavlovsk-Kamchatsky, Russia. The event occurred at a depth of 10.0 km (6.2 miles), with the epicenter near coordinates 53.2°N, 160.7°E.

This earthquake occurred offshore, east of the Kamchatka Peninsula—one of the most seismically active regions of Russia. The closest major city is Petropavlovsk-Kamchatsky, a key regional center with a population exceeding 300,000 people, although many smaller settlements lie along the coastline.

Critical infrastructure in this region could include regional ports on the Sea of Okhotsk, local highway connections to Petropavlovsk-Kamchatsky, and possibly energy facilities serving coastal communities. Due to the offshore nature of the event, some maritime and fishing activities may also be impacted depending on local circumstances.

There is no tsunami threat associated with this earthquake, based on its location and available data.

The maximum estimated intensity reached approximately VI on the Modified Mercalli Intensity scale, and the significance index is 670 (on a scale that runs through 1 000), based on magnitude and estimated impact factors.

The Kamchatka region sits along the Pacific ‘Ring of Fire,’ where the Pacific Plate subducts beneath the North American Plate—making it highly susceptible to frequent, sometimes powerful tectonic earthquakes and volcanic activity.
