Trivia: Which of these national parks is home to a “supervolcano”?
Hawai’i Volcanoes
Pinnacles
Mammoth Cave
Yellowstone
The correct answer is Yellowstone
So why is this answer correct? : Of the many volcanoes in Hawai’i Volcanoes National Park, none of them qualifies as a “supervolcano.” The term is reserved for large volcanoes that have earned the highest possible measurement on the “Volcanic Explosivity Index” (VEI). The Yellowstone Supervolcano is one of them — in fact, it’s so large that much of the national park sits on top of it. The volcano last erupted 640,000 years ago.
