Long Valley Caldera: America’s Most Dangerous Supervolcano Is Recharging!

Long Valley Caldera: America’s Most Dangerous Supervolcano Is Recharging! Beneath the peaks of California’s Sierra Nevada lies one of Earth’s largest active supervolcanoes — a geological time bomb known as the Long Valley Caldera. When it last erupted, it unleashed more than 600 cubic kilometers of magma, blanketing half of North America in ash and plunging the planet into a volcanic winter. The scar of that cataclysm still stretches 20 miles across the landscape, quiet now, but far from dead. Scientists monitoring the caldera have detected the ground slowly rising, gases seeping through the soil, and swarms of tiny earthquakes whispering from the depths. What they’ve discovered is chilling: the magma chamber beneath Long Valley remains partially molten — and it lies in one of the most earthquake-prone regions in the world. A future tremor, even hundreds of miles away, could awaken it.
