Powerful 8.8 earthquake off Kamchatka triggers tsunami alerts across Pacific coastlines.
A massive earthquake measuring 8.8 on the Richter scale struck off the coast of Russia’s Kamchatka Peninsula early Wednesday, prompting a tsunami warning across parts of the Pacific. The US Geological Survey (USGS) reported that the quake occurred at approximately 23:24 GMT on Tuesday, with its epicenter located about 125 km southeast of Petropavlovsk-Kamchatsky, a major city in the far eastern region of Russia.
This is the first earthquake over 8.0 recorded since 2022 and the largest to hit since 2011, according to the USGS. On Nov. 4, 1952, a magnitude 9.0 quake in Kamchatka caused damage but no reported deaths despite setting off 9.1-meter (30-foot) waves in Hawaii. The strongest earthquake was recorded in Chile in 1960. The magnitude was 9.5 on May 22, 1960.
List of top 10 strongest earthquakes ever recorded (United States Geological Survey record)
1. Magnitude 9.5 (1960). Biobío, Chile - It is commonly referred to as the Valdivia earthquake or the Great Chilean earthquake. It is the largest earthquake that claimed the lives of 1,655 people and left 2 million homeless.
2. Magnitude 9.2 (1964). Alaska, USA - Often referred to as the Great Alaska earthquake, the Prince William Sound earthquake, or the Good Friday earthquake, this quake and ensuing tsunami killed 130 people and caused $2.3 billion in damage.
3. Magnitude 9.1 (2004). Sumatra, Indonesia - The Sumatra-Andaman Islands earthquake triggered massive tsunamis and killed more than 280,000 people while displacing 1.1 million across South Asia and East Africa.
4. Magnitude 9.1 (2011). Tōhoku, Japan - It was named the Great Tōhoku Earthquake. It was followed by a subsequent tsunami that killed more than 15,000 people and displaced 130,000 more.
5. Magnitude 9.0 (1952). Kamchatka Krai, Russia - The world's first recorded magnitude 9 earthquake triggered a massive tsunami that struck Hawaii, causing over $1 million in damage.
6. Magnitude 8.8 (2010). Biobío, Chile - The powerful quake occurred offshore near the city of Quirihue and claimed the lives of 523 people and destroyed more than 370,000 homes.
7. Magnitude 8.8 (1906). Esmeraldas, Ecuador - It is referred to as the Ecuador-Colombia earthquake. This quake produced a strong tsunami that killed 1,500 and reached as far north as San Francisco.
8. Magnitude 8.8 (2025) Kamchatka, Russia – An 8.8 magnitude earthquake struck off Russia's far eastern Kamchatka Peninsula at about 11:25 local time on Wednesday (July 30, 2025). A tsunami with a height of 3-4 meters (10-13 feet) was recorded in Kamchatka.
9. Magnitude 8.7 (1965). Alaska, USA - Located near the Rat Islands of Alaska's Aleutian Islands, this earthquake generated a tsunami that was reportedly 35 feet high.
10. Magnitude 8.6 (1950). Arunachal Pradesh, India - Referred to as the Assam-Tibet earthquake, this quake produced intense shaking, triggered sandblows, ground cracks, and large landslides across the region. As many as 780 people were killed due to the quake.
