This is the most powerful earthquake observed since the 2011 Tohoku earthquake in Japan (magnitude 9.1). The 1906 Esmeralda earthquake in Ecuador and the 2010 Biobio earthquake in Chile had reached the same magnitude.
According to data provided by the US Geological Survey (USGS), the magnitude of the Kamchatka earthquake that occurred at 1:25 am has been estimated at 8.8 on the Richter scale, ranking it among the six most powerful ever recorded on the planet.
The earthquake was recorded at a depth of 20.7 kilometers, approximately 126 kilometers from Petropavlovsk-Kamchatsky, the regional capital. Within minutes, global seismic monitoring networks confirmed the magnitude of the phenomenon.
In a sparsely populated but closely monitored region, this earthquake, the magnitude of which has not been seen in the area since 1952, has placed Kamchatka among the few regions to have experienced the strongest earthquakes in history. Its magnitude of 8.8 puts Kamchatka on par with historical earthquakes such as the 1906 Esmeralda earthquake in Ecuador and the 2010 Biobio earthquake in Chile, which reached the same magnitude.
Tonight's earthquake is the most powerful observed since the Tohoku cataclysm in Japan in 2011, which struck the Japanese coast with a magnitude of 9.1, triggering a devastating tsunami and a nuclear accident in Fukushima.
The Kamchatka Peninsula, a 1,250-kilometer strip of land, lies at the intersection of the Pacific tectonic plates. This unstable junction makes it one of the most active and monitored areas on the planet from a seismic and volcanic perspective. Worldwide, only five earthquakes recorded in the past century have exceeded the one tonight.
After last night's earthquake, here are the 10 strongest earthquakes ever recorded:
1. Valdivia, Chile – magnitude 9.5 (1960)
2. Sumatra, Indonesia – magnitude 9.3 (2004)
3. Prince William Sound, Alaska – magnitude 9.2 (1964)
4. Tōhoku, Japan – magnitude 9.0 (2011)
5. Kamchatka, Russia – magnitude 9.0 (1952)
6. Kamchatka, Russia – magnitude 8.8 (2025)
7. Ecuador and Colombia – magnitude 8.8 (1906)
8. Concepcion, Chile – magnitude 8.8 (2010)
9. Rat Islands, Alaska – magnitude 8.7 (1965)
10. Sumatra, Indonesia – magnitude 8.6 (2005)
Alerts were also issued in Alaska, Hawaii and along the entire Pacific coast as far as New Zealand. Russian areas closest to the epicenter of the earthquake on the Kamchatka Peninsula reported damage and evacuations, but no serious injuries.
The epicenter of the earthquake was located approximately 119 kilometers southeast of the Russian city of Petropavlovsk-Kamchatsky, a city of 180,000 people on the Kamchatka Peninsula. Several aftershocks with a magnitude of 6.9 were recorded. The first wave of the tsunami hit the coastal area of Severo-Kurilsk, the main settlement in Russia's Kuril Islands in the Pacific. Local governor Valery Limarenko said residents were safe and would stay on high ground until the risk of a second wave was averted.
