It is off the Kamthatka peninsula, not far from this huge strip of land of 1,250 kilometers located in the Russian Far East, that a depth of 21 kilometers under the sea and 126 kilometers from the coast, one of the most powerful trees never recorded in the region. An earthquake of magnitude 8.8 on the Richter scale, causing alerts to the tsunami in several regions of the Pacific, as in Hawaii or north and east of Japan, located near the epicenter.

Since 1952, it is the highest magnitude ever recorded in the peninsula, reputed to be eminently subject to earthquakes because it is located at the junction of the Pacific’s tectonic plates (Okhotsk plate) and North America. On a world level, this earthquake is 6e The most powerful earthquake ever measured on earth, according to the American Institute of Geophysics (USGS).
Here is which earthquakes have surpassed it:
-
1. Chile, Biobío region (May 22, 1960)
Magnitude: 9.5
It is the most powerful earthquake that has ever been recorded in South America. He struck southern Chile, in the Biobío region, causing a transpacific tsunami that has spread to Hawaii, Japan and the Philippines, with waves that can sometimes reach 25 meters.
Human record: more than 2,000 dead and 2 million homeless.
Geologically, the Biobío earthquake has led to several field sags in Valdivia and a ground rise in certain regions. The course of certain rivers has also been changed.
-
2. Alaska, Prince-William Bay (March 27, 1964)
Magnitude: 9.2
A 4 -minute and 38 second earthquake upset the Alaskian relief. It is, to date, the longest earthquake ever measured.
Assessment: 131 dead.
Notable fact: the earth has lifted several meters (up to 11 meters) in places; The coasts were redesigned.
-
3. Japan, Tōhoku (March 11, 2011)
Magnitude: 9.1
An earthquake followed by a devastating tsunami struck northeast Japan.
Human assessment: more than 18,000 dead and missing.
A major consequence: the earthquake caused a nuclear accident at the Fukushima plant. A disaster that will be experienced as an international trauma.
-
4. Indonesia, off Sumatra (December 26, 2004)
Magnitude: 9.1
The underwater earthquake caused a gigantic tsunami, affecting 14 countries riparian from the Indian Ocean.
Human record: around 230,000 dead.
Global impact: human losses are such that the earthquake causes a Copernican revolution in alert. New tsunamis alert systems and an emergency protocol dedicated to this natural disaster are then born on a global scale.
-
5. Russia, Kamthatka (November 4, 1952)
Magnitude: 9.0
It is the first major earthquake identified in the Kamchatka region.
Assessment: few victims with regard to the low population density living in the region, almost desert. But this shock causes a major tsunami reaching the coasts of Hawaii, with waves of up to 15 meters.
Historical fact: the Kamchatka earthquake is one of the first earthquakes to be the subject of global geophysical follow -up.
A new historical earthquake strikes Russia this July 30, 2025
The latest, placed 6e In the ranking, the one occurred this July 30, 2025 in Kamthatka. Few human losses have been recorded at this stage. Four whales were found stranded on the Japanese coast, near Chiba.
To illustrate the intensity of such seismic tremors, an earthquake of magnitude 5 corresponds roughly to the energy released by the nuclear bomb dropped during the Second World War on Hiroshima…
The most powerful earthquakes recorded Essentially concentrate in the Pacific Fire belt, a particularly intense tectonic region, where lithospheric plates collided or slide under each other.
