Is the Yellowstone Caldera in Yellowstone National Park?
Hike/auto/bus. The Yellowstone Caldera is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States, sometimes referred to as the Yellowstone Supervolcano.
Is the Yellowstone Caldera overdue for a supereruption?
Although fascinating, the new findings do not imply increased geologic hazards at Yellowstone, and certainly do not increase the chances of a ’supereruption‘ in the near future. Contrary to some media reports, Yellowstone is not ‚overdue‘ for a supereruption.
Who is the author of the Yellowstone Caldera chronicles?
Caldera Chronicles is a weekly article written by U.S. Geological Survey Yellowstone Volcano Observatory scientists and colleagues. Silver Gate—the Mammoth Terraces of yesteryear!
When was the most recent eruption of Yellowstone Caldera?
The most recent lava flow occurred about 70,000 years ago, while a violent eruption excavated the West Thumb of Lake Yellowstone around 150,000 years ago. Smaller steam explosions occur as well: an explosion 13,800 years ago left a 5 km (3.1 mi) diameter crater at Mary Bay on the edge of Yellowstone Lake (located in the center of the caldera).
When was the last time the Yellowstone Caldera erupted?
The Yellowstone supervolcano last erupted about 640,000 years ago. When it did, it left behind a caldera, a landform created by the inward collapse of a volcano’s peak. This simple map outlines the extent of the Yellowstone Caldera, as well as some basic physical features of the region.
Who is the expert on the Yellowstone Supervolcano?
The Yellowstone “supervolcano” is a topic surrounded by much curiosity and—sometimes—speculation. For the real facts, we went straight to an expert, Jake Lowenstern of the U.S. Geological Survey (USGS).
