🔆 Kamchatka Peninsula (Russia)

📍 Why in News?

✅ A magnitude 8.8 earthquake struck off the coast of Russia's Kamchatka Peninsula, triggering tsunami warnings across several Pacific countries. ✅ The earthquake occurred along the Kuril–Kamchatka subduction zone, one of the world's most seismically active regions.

📍 About Kamchatka Peninsula

✅ A peninsula located in Russia's Far East.
✅ Lies between the Sea of Okhotsk (west) and the Bering Sea & Pacific Ocean (east).
✅ Covers an area of approximately 270,000 sq. km.
✅ Sparsely populated with Petropavlovsk-Kamchatsky as its largest city.

📍 Key Features

✅ Part of the Pacific Ring of Fire.
✅ Home to over 300 volcanoes, including nearly 30 active volcanoes.
✅ Contains the famous Valley of Geysers, one of the largest geyser fields in the world.
✅ Includes UNESCO World Heritage Site – Volcanoes of Kamchatka.
✅ Rich habitat for brown bears, Pacific salmon, Steller's sea eagle, and marine mammals.

📍 Why is Kamchatka Highly Earthquake-Prone?

✅ Located at the convergent boundary between the Pacific Plate and the Okhotsk (North American) Plate.
✅ The denser Pacific Plate subducts beneath the Okhotsk Plate, generating powerful earthquakes and volcanic eruptions.
✅ Frequent seismic activity makes it one of the most active tectonic regions globally.

📍 Importance

✅ Global centre for earthquake and volcano research.
✅ Important region for monitoring tsunamis in the Pacific Ocean.
✅ Supports unique biodiversity and protected ecosystems.
✅ Significant for understanding plate tectonics and disaster management.

📍 UPSC Value Addition

✅ Pacific Ring of Fire accounts for nearly 75% of the world's active volcanoes and about 90% of global earthquakes.
✅ Subduction Zone: A tectonic boundary where one plate sinks beneath another, generating earthquakes, volcanoes, and tsunamis

📍 Prelims Facts

✅ Highest active volcano in Eurasia – Klyuchevskaya Sopka.
✅ The Kuril–Kamchatka Trench lies off the eastern coast of the peninsula.
✅ Kamchatka is part of the Circum-Pacific Seismic Belt (Ring of Fire).
