America's Armageddon: The Untold Story of Yellowstone's Supervolcano

🌋Yellowstone's supervolcano has the potential for catastrophic eruptions that could impact the entire planet.

📉While the risk of a catastrophic eruption is low, experts continue to monitor Yellowstone for signs of volcanic activity.

🌍The last eruption of a supervolcano occurred over 26,000 years ago at New Zealand's Lake Taupo.

💥Supereruptions release massive amounts of debris and gases, potentially dimming the sun and causing global cooling.

🌄Yellowstone's volcanic activity created its unique landscape, including geysers, hot springs, and mud cauldrons.
