Yellowstone timebomb – Over 11,000 MILES of magma just waiting to spew from park

MORE than 11,000 cubic miles of magma is waiting to burst from beneath the world's most dangerous volcano in Yellowstone National Park in the US

Deep magma reservoirs, such as that below the Yellowstone caldera, are the key to causing volcanic ‘super-eruptions’, that could threaten millions of lives, new research suggests.

If a mega eruption of Yellowstone, one of the world’s largest supervolcanoes, happened so much toxic ash and moult on rock would be hurled into the atmosphere it could block out sunlight and trigger a nuclear-winter type effect or even a mini ice age.

An international team of geologists carried out the study which shows the importance of large magma reservoirs in creating Earth’s most powerful volcanic eruptions.

The researchers claim that the most powerful volcanic eruptions, dubbed ‘super-eruptions’, are triggered by a slow and steady drip feed of magma from large reservoirs deep within the Earth’s crust into smaller reservoirs closer to the surface.
