🔆 Global Distribution of Earthquakes

📍 Major Seismic Belts
✅ The circum-Pacific seismic belt found along the rim of the Pacific Ocean is the world’s greatest earthquake belt. Around 81% of the world’s largest earthquakes occur here. Known as the “Ring of Fire”.

✅ The Alpide earthquake belt spreads from Java to Sumatra, through the Himalayas, the Mediterranean, and into the Atlantic. It causes about 17% of the world’s earthquakes.

✅ The third belt is the mid-Atlantic Ridge, a submerged divergent plate boundary where tectonic plates are spreading apart.

🔆 Seismic Mapping of India

📍 Seismic Zonation Insights
✅ About 59% of India’s land area is prone to earthquakes.

✅ The seismic map classifies India into 4 seismic zones based on intensity.

✅ Zone V is the most active (Very High Risk), while Zone II is the least active.

➤ Approx. 10.79% in Zone V, 17.49% in Zone IV, 30.79% in Zone III, and 40.93% in Zone II.
