What is the origin of volcanic activity at Yellowstone?
Magma, Hot Spots, and the Yellowstone Supervolcano. Magma (molten rock from below the earth’s crust) is close to the surface in the greater Yellowstone area. This shallow body of magma is caused by heat convection in the mantle. Hot spots leave a trail of volcanic activity as tectonic plates drift over them.
Is the eruption in 2012 realistic?
While much of the plot of 2012 is purely fictional, the Yellowstone supervolcano is not simply a screenwriter’s speculation. The supervolcano activity in Yellowstone appears to be on a 700,000 year cycle–give or take 50,000 years.
How many giant eruptions have occurred at Yellowstone?

How often do volcanic eruptions occur at Yellowstone? Three extremely large explosive eruptions have occurred at Yellowstone in the past 2.1 million years with a recurrence interval of about 600,000 to 800,000 years.
Is Yellowstone a dormant volcano?
Q: Is the volcano dormant or extinct or still active? A: The Yellowstone Volcano is still active. Evidence for the activity of the Yellowstone Volcano are the 1,000 to 3,000 earthquakes per year, active ground deformation, and the over 10,000 thermal features found in Yellowstone.
Are supervolcanoes real?
There are many supervolcanoes around the world other than Yellowstone, including California’s Long Valley, Japan’s Aira Caldera, Indonesia’s Toba, and New Zealand’s Taupo. This latter supervolcano is the last to have ever released a super-eruption, which burst free some 26,500 years ago.
