🔆 Cold Lava (Lahar): A Silent but Deadly Force

📍 Context: The Mount Kanlaon volcano in the Philippines recently witnessed rivers of cold lava, also known as lahars.

📌 What is Cold Lava (Lahar)?
✅ A fast-moving slurry of water, volcanic ash, rock fragments, and pumice.
✅ Forms when volcanic ash mixes with heavy rain or when glacial ice melts, even without eruptions.
✅ Moves at high speeds, reaching hundreds of km/h, making it more dangerous than slow-moving lava.
✅ Hot & destructive**—traps heat, **burns everything in its path, causes property damage & loss of life.
✅ Creates floods by damming rivers, harming ecosystems, and increasing flood risks.

⚠️ How to Mitigate Lahars?
✅ Early warning systems & engineering solutions can reduce damage.
✅ Community education on lahar-prone zones saves lives.

🌋 Lava vs. Magma:
🟠 Magma – Found inside the Earth (molten rock in the mantle).
🔴 Lava – Magma that has reached the surface through a volcanic vent.
