Scientists find giant reservoir of magma under eastern horn of Africa

October 3, 2011ETHIOPIAAfrica splitting in two: A giant underground reservoir of molten rock has been discovered under the deserts of Ethiopia by British geologists, The (London) Sunday Times reported. They targeted the Afar region in the Horn of Africa after a recent surge in volcanic activity and earthquakes plus the appearance of giant cracks in the rocky surface. Tectonic plates in the area are pulling apart and gradually creating a new ocean. Now, the scientists have mapped the colossal underground lake of magma that lies up to 20 miles (32km) below the earth’s surface. “We estimate that there is 3,000 cubic kilometers of molten rock under Afar — enough to cover all of London … with around a kilometer of rock,” said Kathy Whaler, professor of geophysics at Edinburgh University. The reservoir is under such pressure that it has forced tongues of molten rock up towards the surface, producing eruptions and earthquakes. In 2005, a 25-foot (7.6m) wide tongue of lava spread 40 miles (64km) under Afar in 10 days and solidified, and many more followed. Afar lies in east Africa’s Great Rift Valley at a point where three tectonic plates are pulling apart from each other. Such movement creates gaps, or rifts, in the Earth’s crust, which allows molten rock to well up from deep below. There are thousands of miles of these rifts around the world but almost all lie deep below the ocean. East Africa and Iceland are the only places where they emerge on to land. Much of Afar is already below sea level but is protected from flooding by a barrier of low hills in Eritrea. Geologists believe the protective barrier will be overcome in about one million years, allowing the Red Sea to inundate the whole area. Whaler, who presented her preliminary results to the UK’s Royal Society last week, said, “Over geological time parts of southern Ethiopia and Somalia will split off and form a new island that moves out into the Indian Ocean.” –Fox News

  1. Map shows rift going up through Israel?

  2. Thank you Alvin and George. This is fascinating. I wasn’t aware of the magma reservoir.

    I’m guessing that’s what happened to tiny little Madagascar millions of years ago….and why it now sit out there in the Indian Ocean. And even before that ‘trillions’ of years ago maybe all land was connected. If you look at the world map it looks like a puzzle whose pieces have been scattered about. (whose?)

    We’ve always lived in a changing world however, as it stands now we are able through word of mouth and technology see and feel that change.

    Love lift us up……….Maranatha

      I think this shows evidence of the kind of change that can ‘rapidly’ occur. Science continues to show more evidence for a young earth

    In that day His feet will stand on the Mount of Olives, which is in front of Jerusalem on the east; and the Mount of Olives will be split in its middle from east to west by a very large valley, so that half of the mountain will move toward the north and the other half toward the south.
