'Sleeping' supervolcanoes 'could erupt much more quickly than we thought'

Yellowstone supervolcano

Some 630,000 years ago, a massive eruption rocked the region, spewing the rock and ash that created the Yellowstone caldera, a 40-mile-wide bowl that forms most of the park.

- Arizona State University researchers have analyzed minerals around the supervolcano at Yellowstone National Park and have come to a startling conclusion. What they discovered surprised them - the changes in temperature and composition only took a few decades, much faster than the centuries previously thought.

If the supervolcano underneath Yellowstone erupts again, we may have far less advance warning time than we thought.

Though no one is attempting to put a time frame on the next eruption, Hannah Shamloo of Arizona State University observed that it is "shocking how little time is required to take a volcanic system from being quiet and sitting there to the edge of an eruption".

Ash from a mega-eruption at Yellowstone would spread across the USA, covering nearby states such as Wyoming, Idaho, Colorado and Montana in up to three feet of ash, according to a 2014 study of what might happen if a supervolcano erupted, and blanketing the Midwest and other parts of the US, killing animals and plants, affecting the power grid and destroying buildings, causing a volcanic winter.

According to The Times, Shamloo later analyzed crystals from the team's dig that recorded changes in temperature, pressure and water content beneath the volcano - much like a set of tree rings. The pair also presented an earlier version of their study at a 2016 meeting of the American Geophysical Union.

Given that eruptions of supervolcanoes buried on our planet-and there are several-are thought to occur every 100,000 years or so, however, the likelihood of such an event during your lifetime is small, reports the New York Times.

In 2011, scientists revealed that the ground above the magma chamber bulged by up to 10 inches in a span of about seven years.
