It's NOT Just a Flood: 3 Stages of a Mountain Collapse 🌪️

The first mistake in understanding a Himalayan mountain collapse is thinking it's just an "ordinary river flood." ❌🌊 In reality, a mega-disaster is a terrifying, EVOLVING mass flow that mutates through 3 deadly stages: 1️⃣ Ice-Rock Avalanche: It starts high up on a steep slope, with massive solid blocks of bedrock and glacier ice failing and fragmenting. 🧊🪨 2️⃣ Debris Flow: As it accelerates down steep gullies, it swallows loose sediment, snow, and water, transforming into a thick, fast-moving debris flow. 🌪️ 3️⃣ Mega-Flood: Finally, it hits the river network, becoming a massive, debris-rich flood racing towards downstream borders like the Gyirong Valley. 🌊 During those crucial first 7 minutes, the disaster's composition, geometry, and the terrain controlling it are constantly changing. Rock avalanches, debris flows, and river floods DO NOT move the same way—and understanding that distinction is the key to surviving them. 👇 Which of these 3 stages do you think is the most destructive?
