Ring of Fire
Why it Matters?
An 8.8 magnitude earthquake struck the Kamchatka Peninsula in Russia on July 31, 2025, triggering a Pacific-wide tsunami but causing no casualties due to the sparse population.
What You Should Know?
Ring of Fire encircles the Pacific Ocean and is responsible for over 80% of the world’s largest earthquakes.
Major countries on the Ring of Fire are Russia, Japan, the Philippines, Indonesia, Australia, New Zealand, Chile, Peru, Mexico, and the USA.
The largest recorded earthquake (magnitude 9.5) occurred in Chile in 1960 and is also along this belt.
Earthquakes of magnitude more than 8.5 are rare, with only 5 such events in the past 20 years.
What causes the intense geological activity in the Ring of Fire?
The Ring of Fire is located at the boundaries of several tectonic plates, including the Pacific Plate, which is the largest.
These plates are constantly moving and interacting with each other, leading to subduction zones and transform faults. These geological processes create the conditions for volcanic eruptions and earthquakes.
Other Major Seismic Zones:
The Alpide belt is the Earth’s second major seismic zone. It stretches from Indonesia to Turkey, including the Himalayas.
The mid-Atlantic ridge is the third major seismic zone, but it produces weaker, deep-ocean earthquakes.
Note:
Kamchatka Peninsula lies in Russia's far east and is part of the "Ring of Fire", a highly seismically active region.
