When Nature Strikes - Volcanoes

Volcanoes are powerful natural disasters, with supervolcanoes having the potential to impact life globally. The Long Valley Caldera in California is a prime example of a supervolcano, with its eruption spreading debris across the U.S. and affecting the world. Geologist Michael Manga studies these phenomena to understand and predict volcanic behavior. Volcanoes vary in type, from shield to stratovolcanoes, and are influenced by mantle activity. Supervolcanoes form massive magma chambers, leading to explosive eruptions. Yellowstone is another supervolcano under observation, with potential global impacts. Ongoing research aims to improve eruption predictions, potentially saving lives.
