Shallow M6.6 earthquake hits southeast of Petropavlovsk-Kamchatsky, Russia
An earthquake with a magnitude of M6.6 was registered at 06:51 UTC on June 19, 2026, approximately 185 km (115 miles) southeast of Petropavlovsk-Kamchatsky, Russia. The event occurred at a shallow depth of 10.0 km (6.2 miles), according to USGS data.
The coordinates place the earthquake offshore in the North Pacific, south of the Kamchatka Peninsula near 52.2°N, 160.9°E. This region lies along the Pacific Ring of Fire, an area known for frequent and sometimes powerful seismic activity due to tectonic plate interactions.
The affected area is generally distant from major population centers, with infrastructure such as international shipping routes and regional fisheries potentially in the broader vicinity. There are no immediate indications of urban infrastructure being impacted.
There is no tsunami threat associated with this earthquake, based on its location and available data.
The significance index is 670 (on a scale that runs through 1 000), calculated from magnitude, location, and other available impact indicators.
Kamchatka is a seismically active region situated along the convergent boundary between the Pacific Plate and the North American Plate. The area experiences regular substantial seismic events as a result of ongoing subduction processes.
