Kamchatka Peninsula [Russia], November 3 (ANI): An earthquake measuring 6.1 on the Richter scale struck off the East Coast of Kamchatka on Monday, according to the National Centre for Seismology (NCS).
The quake occurred at a shallow depth of 10 kilometers, making the area prone to potential aftershocks, the NCS said.
In a post on X, the NCS stated, “EQ of M: 6.1, On: 03/11/2025 14:14:40 IST, Lat: 52.37 N, Long: 160.17 E, Depth: 10 Km, Location: Off East Coast of Kamchatka.”
Earlier in the day, another earthquake of magnitude 6.3 struck the Pacific Ocean, also at a depth of 10 kilometers.
In a separate post on X, the NCS reported, “EQ of M: 6.3, On: 03/11/2025 12:40:23 IST, Lat: 52.41 N, Long: 159.93 E, Depth: 10 Km, Location: Pacific Ocean.”
Shallow earthquakes are generally more destructive than deeper ones because their energy is released closer to the Earth’s surface, leading to stronger ground shaking and potentially greater damage and casualties.
The Kamchatka Peninsula in far eastern Russia is one of the world’s most seismically active regions. It lies at the junction of the Pacific and North American tectonic plates, making it a hotspot for earthquakes and volcanic activity.
The Alaska-Aleutian subduction system, which includes the Kamchatka region, is among the most seismically active zones globally, having produced more magnitude 8 or higher earthquakes over the past century than any other region. Many of these quakes, along with coastal and submarine landslides, have generated tsunamis.
The region is home to more than 130 volcanoes and volcanic fields and accounts for over three-quarters of U.S. volcanoes that have erupted in the last two centuries.
The southern Kamchatka Peninsula lies above a convergent plate boundary where the Pacific Plate subducts beneath the Okhotsk microplate along the Kuril-Kamchatka Trench, with the plates converging at a rate of about 86 millimeters per year. Earthquakes in this zone occur along the megathrust boundary between the two plates, within the descending Pacific Plate, and in the overriding Okhotsk Plate.
Meanwhile, the northern part of the peninsula lies farther from the main subduction zones but sits on the boundary between two blocks of the North American Plate—the Kolyma-Chukotka and Bering Sea microplates. This boundary experiences both compression and right-lateral strike-slip motion along large southwest-northeast trending faults. (ANI)
