Is the Earth cooking up another supervolcano?

February 11, 2013 GEOLOGYEvery few million years or so, the Earth burps up a gargantuan volcano. These aren’t like volcanoes in our lifetimes; these “super volcanoes” can erupt continuously for thousands of years. While they might be rare, you’d best look out when one hits. The ash and volcanic gases from these volcanoes can wipe out most living things over large parts of the planet. Michael Thorne, a seismologist at the University of Utah, has some clues about what causes these big eruptions. thorne uses seismic waves to get a picture of what’s going on about 1,800 miles beneath the Earth’s surface, where the planet’s core meets the outer mantle. Think of the Earth as an avocado, and the pit is the core. The stuff you make guacamole with is the outer mantle. Thorne has been watching two enormous piles of rock that sit on the boundary between the core and the mantle. One pile is underneath the Pacific Ocean; the other under Africa. Scientists have known about them for 20 years, but Thorne saw something different. “I think this is the first study that might point to evidence that these piles are moving around,” Thorne says. Moving perhaps, but slowly and the piles are maybe 3,000 miles across. Thorne thinks, in fact, that the pile under the Pacific is actually two piles crushing up against each other. And where they meet, there’s a blob. “We call it a blob of partially molten material,” he says. “I mean it’s big … this one that we found is an order of magnitude, maybe 10 times larger, than any of the ones we’ve observed before.” The blob is the size of Florida, and there are other, smaller blobs around the edges of the piles, too. So these great rock piles are being squished together and squeezing this huge molten blob at the middle of it like some kind of balloon, and it is going on right underneath us- rr at least, under Samoa. So should we care about these blobs? “A possibility is that these blobs might represent sort of a deep-seated root, to where plumes arise all the way to the surface, giving rise to hot-spot volcanism,” Thorne says. One example is the Yellowstone super volcano, which has blown its top three times in the past 2 million years. -NPR

    Seems this old Earth is getting “fed up” and making plans for the New World that is coming

    Scriptures say as long as the world endures there will always be seed time and harvest, cold and heat, summer and winter, day and night will never cease. That would be Genesis 8:22.
    I think the key phase in this is “as the world endures”

    The word endure from the dictionary meaning: (v) bear hardship, to experience exertion, pain or hardship without giving up. survive, to last or survive over a period of time,especially when faced with difficulties.

    To bring it home::::Endure a visit to the doctors office…..Endure a visit from the mother-in-law or father-in-law.

    The creation is enduring separation from the creator…

    Just my opinion……..

    off-post comment………..
    Two major prophetic events happening now as I keyboard this on 02.11.13.
    1) The removal of the USA as the world’s superpower and the transition of power to the east.
    2) The retirement of the current Pope and the installment of a new one by Passover(Easter).
    Pope number 113 and maybe the pope many believe will be the final and false prophet who
    will allegedly turn against the church. Unexpected……..Something stirring………?

    Another event……….A reported super volcano stirring in Italy…. Could this cause Rome to be
    destroyed as some have wrote and the Vatican/Pope move to Jerusalem…………?

    We must remember, The anti-christ will be able to call fire down from heaven…..To me, that
    means that he will have the ability to start earthquakes, hurricanes and other natural disasters
    in order to persuade the world he is god…………and to be worshiped.

    Thought I would throw this out this morning…………
