🔆 The Kamchatka Quake & the Ring of Fire

📍 What Happened?
✅ A massive 8.8 magnitude earthquake struck the Kamchatka Peninsula, Russia’s far-east, on July 30, 2025
✅ It triggered 3–4 metre tsunami waves along Kamchatka and parts of Hawaii, though no casualties were reported
✅ It’s one of the strongest earthquakes in recorded history, part of the Circum-Pacific Seismic Belt (aka Ring of Fire)

📍 Ring of Fire: World’s Most Seismically Active Zone
✅ Accounts for 80% of world’s strongest earthquakes
✅ Formed by subduction zones where oceanic plates collide with continental plates
✅ Countries affected: Japan, US (Alaska & West Coast), Russia, Indonesia, Chile, Philippines, New Zealand, etc.

📍 Kamchatka’s Seismic Significance
✅ Kamchatka and Kuril Islands are among the most earthquake-prone zones
✅ Region has seen 130+ magnitude 7+ earthquakes since 1900
✅ The July 30 quake was second only to Japan’s 2011 Tohoku quake (9.1) in the last 20 years

📍 Other Active Earthquake Belts
✅ Himalayan Belt – less active than the Ring of Fire but highly destructive due to shallow focus
✅ Mid-Atlantic Ridge – mostly undersea, moderate intensity

📍 Why No Casualties This Time?
✅ Region is sparsely populated (0.62 people/km²)
✅ No major tsunami impact despite high magnitude
✅ Shows importance of disaster-resilient infrastructure

📝 Prelims Question
Q. The “Ring of Fire” is associated with:
A. Deserts and drought-prone zones
B. Frequent volcanic eruptions and earthquakes ✅
C. Major oil reserves
D. Large-scale deforestation zones

🖋️ Mains Question (GS1 – Geography)
Q. Explain the geographical features and tectonic processes responsible for the frequent seismic activity along the Circum-Pacific Belt. Why is the Kamchatka region significant in this context?
