    Yellowstone Supervolcano May Rumble to Life Faster Than Thought

    A new study of ancient ash suggests that the dormant giant could develop the conditions needed to blow in a span of mere decades.

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

    After analyzing minerals in fossilized ash from the most recent mega-eruption, researchers at Arizona State University think the supervolcano last woke up after two influxes of fresh magma flowed into the reservoir below the caldera.

    And in an unsettling twist, the minerals revealed that the critical changes in temperature and composition built up in a matter of decades. Until now, geologists had thought it would take centuries for the supervolcano to make that transition.

    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 also think the reservoir is drained after every monster blast, so they thought it should take a long time to refill. Based on the new study, it seems the magma can rapidly refresh—making the volcano potentially explosive in the geologic blink of an eye.

    “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,” study co-author Hannah Shamloo told the New York Times.

    Still, Yellowstone is one of the best monitored volcanoes in the world, notes Michael Poland, the current Scientist-in-Charge of the Yellowstone Volcano Observatory for the U.S. Geological Survey. A variety of sensors and satellites are always looking for changes, and right now, the supervolcano does not seem to pose a threat.

    "We see interesting things all the time ... but we haven't seen anything that would lead us to believe that the sort of magmatic event described by the researchers is happening," says Poland via email, adding that the research overall is "somewhat preliminary, but quite tantalizing."

    The new paper adds to a suite of surprises scientists have uncovered over the last few years as they have studied the supervolcano. (Also find out about a supervolcano under Italy that has recently been rumbling.)

    Gotta chime in on this , according to Sfath the great cauldara will erupt , and has been building for thousands of years ... according to the information , they traveled back in time to view the last eruption, made calculations , as well as using their psychic people (their race has gifted individuals like ours) the volcano will will erupt and cause much devastation and cost many lives ... everything is a circle, it builds , it blows, it builds , it blows ... Has always done this and will continue to follow nature’s circle/cycle of life ... They also speak of La Palma in Italy, we are urged to grade down the west side of the mountain to lessen the tsunami that will be created when it erupts ...they say part of the west side will break off and slide into the ocean creating a tsunami that will affect the east coast of America... Even though I keep pressing them, they won’t give the exact date, because warnings were given in the past and mankind took no heed to their warnings... They warn , Yellowstone will blow, Oregon will experience a mega sea quake, a volcano in The Canary Islands will effect America, typhoons, firestorms, floods, will come to America for her reaping of what she has sown across the world , in trying to acheive global domination... they have warned about these events for over 60 years ...
