Geologists at Brigham Young University have discovered what may be the world’s largest “super” volcano that erupted in Utah’s own backyard.
While there are a variety of volcanoes that blast away in different ways, super volcanic eruptions are the biggest that collapse into large calderas. Yellowstone Park is the remains of one of those calderas and it’s still very much alive and active.
But, geologists think they may have found an equally as big if not bigger super volcano, one that shook up western Utah and eastern Nevada 30 million years ago. The eruption is hardly visible to the naked eye now, but underneath and in surrounding formations, the evidence was waiting to be uncovered.
At ~6000 cubic kilometres it is certainly a big one, but I wonder how many undiscovered large caldera like this there are around the world? Covered now by sea, or eroded so we cannot see, we shall never know however I suspect many in Earth’s more turbulent past.
