The volcano beneath the Yellowstone National Park could erupt sooner than previous predictions, according to researchers. As per the new study, researchers have found that changes in temperatures during previous eruptions can lead to the blast to occur quicker than expected. Researchers say that we may have less advance warning time than we thought before the eruption actually occurred. Researchers at Arizona State University said that the supervolcano has woken up after two influxes of fresh magma flowed into the reservoir below the caldera. Scientists determined the increase rate of temperature change by analyzing minerals in fossilized ash. According to National Geographic, a powerful eruption which occurred roughly 630,000 years ago shook the region completely creating the Yellowstone caldera which is about 40 miles wide.
Earlier, scientists believed that the reservoir is drained out after every blast and would take a long time to refill. However, as per the new study, the magma can rapidly refill making the volcano explosive within a short span of time. A 2013 study, for instance, showed that the magma reservoir that feeds the supervolcano is about two and a half times larger than previous estimates. Scientists said that however there is nothing to be a worry as the temperature around the volcano would be increased only over a period of decades and not centuries, as per earlier understandings.
Hannah Shamloo, the study’s co-author was quoted by the New York Times as saying, “It’s shocking how little time is required to take a volcanic system from being quiet and sitting there to the edge of an eruption.” However, if the volcano is to erupt tomorrow then it would cover major portions of the United States and the Earth’s atmosphere in dangerous ash. As per reports, ash in the atmosphere would cool the planet while it could have devastating effects if it does not disappear quickly.
