Pacific Ring of Fire || Tectonic Plates, Volcanoes & Tsunamis UPSC Geography & Current Affairs 2025

Master the Pacific Ring of Fire—a must-know UPSC Geography & Environment topic linking plate tectonics, earthquakes, volcanoes, and current affairs. This video explains why the Ring of Fire, also called the Circum-Pacific Belt, is Earth’s most seismically active region, accounting for 75% of active volcanoes and nearly 90% of global earthquakes. Learn the location and extent of this 40,000-km horseshoe around the Pacific Ocean touching Japan, Indonesia, Philippines, Chile, Alaska, California, New Zealand, and Russia’s Kamchatka Peninsula. Understand the 2025 Kamchatka 8.8 magnitude earthquake and tsunami that highlight the Ring’s enormous hazards for millions living along its edge. Key topics include: Tectonic processes—subduction zones, transform faults (San Andreas), divergent boundaries, and hot spots. Major features—iconic volcanoes like Mount Fuji, Mount St. Helens, deep trenches such as the Mariana Trench, and towering ranges like the Andes. Human significance—why volcanic soils are fertile, how geothermal energy and mineral deposits support economies, and how repeated disasters demand strong disaster-management systems. Famous quakes & eruptions—Chile 1960, Alaska 1964, Japan 2011, Indonesia 1883 (Krakatoa). Perfect for UPSC IAS Prelims & Mains (GS-I Geography, GS-III Disaster Management) and other competitive exams, this lesson links current affairs with static syllabus, gives map-based explanations, and provides Mains-ready points on disaster preparedness, resource potential, and global tectonics. Stay ahead in UPSC 2025 with clear, exam-oriented insights into the world’s most dangerous seismic belt. #geopolitics #career #latest #news #currentnews #hindi #internationalnews #latestupdate #currentaffairs #latestnews #PacificRingOfFire #RingOfFire #UPSC #IAS #Geography #CurrentAffairs #Earthquakes #Volcanoes #gsdhillon #brainrootsias #PlateTectonics #DisasterManagement #UPSCPrelims #UPSCMains #GeographyOptional #Tsunami #EarthScience #KamchatkaEarthquake #UPSC2025 #EnvironmentAndEcology #SeismicHazards #GeothermalEnergy
