    The Anglo-Saxon Chronicle states that in England 1014 AD, on the eve of St. Michael’s day (September 28, 1014) “came the great sea-flood, which spread wide over this land, and ran so far up as it never did before, overwhelming many towns, and an innumerable multitude of people.” This is clearly a reference to a tsunami similar to the one that struck Indonesia in December 2004 which killed over 250,000 people. What could have caused this tsunami? Could a meteor or comet impact in the Atlantic Ocean have been the cause? Researcher Dallas Abbott of the Lamont Doherty Earth Observatory...

    A meteorite impact off Long Island 2,300 years ago may have set off a huge tsunami that flooded the New York City region, a new study says (New York City and Long Island map). It's not known whether any ancient settlements were in the path of the proposed killer waves, but "any significant tsunami today would be devastating and likely to flood places like lower Manhattan," Vanderbilt University geologist Steven Goodbred said. Tsunamis are typically triggered by seismic events. An undersea earthquake, for example, caused the catastrophic 2004 Indian Ocean tsunami. But meteorite strikes have also been known to spark...

    Dallas Abbott The Fenambosy chevron, one of four near the tip of Madagascar, is 600 feet high and three miles from the ocean. At the southern end of Madagascar lie four enormous wedge-shaped sediment deposits, called chevrons, that are composed of material from the ocean floor. Each covers twice the area of Manhattan with sediment as deep as the Chrysler Building is high. On close inspection, the chevron deposits contain deep ocean microfossils that are fused with a medley of metals typically formed by cosmic impacts. snip... The explanation is obvious to some scientists. A large asteroid or comet,...

    It's bad enough when, every few million years, an asteroid rocks our planet. It's worse if the impact triggers regional or global volcanic activity, which is not only hazardous to nearby plants and animals but can choke Earth's atmosphere with deadly gases for months or years. But there's also a possible bright side, like the birth of nice places like Hawaii. For more than three decades, scientists have explored the question of whether an asteroid impact could cause significant volcanic eruptions, hot spots that spring up out of nowhere and create new landforms or rearrange old ones. The process might...

The expedition is going to remote Mason Bay on the west coast of Stewart Island to...

    In 1989, Edward Bryant climbed a point on the southeast coast of his native Australia with a colleague and found an odd jumble of boulders well above the surf. A big wave, he thought, maybe a tsunami from an earthquake, must have tossed them up there. Over the next few years, however, the University of Wollongong geologist explored hundreds of miles of coast and found more signs of wave action, hundreds of feet above the water--too high for any quake-spawned surge. An astonishing hypothesis of devastation from outer space formed in his mind. It gathered some praise, along with many...

    Maine Crater Related to Dino-Killer Asteroid? By Larry O'Hanlon, Discovery News April 3, 2003 — The evidence is still skimpy, but there is a chance that the dino killer asteroid was not alone when it walloped the Earth 65 million years ago. A possible second crater, at least as big or bigger than the famous Chicxulub crater off Mexico's Yucatan peninsula, may have been created by a second hit moments after Chicxulub and off the coast of Maine. "It probably is a crater, but we really don't have age data," said marine geologist Dallas Abbott Lamont-Doherty Earth Observatory at Columbia...

    HOW IMPACTS CAN TRIGGER VOLCANOS Large asteroid impacts have nasty side effects, as any dinosaur could have told you were she not obliterated by one of these calamity combos 65 million years ago. The ground shakes. Fire arcs across the sky and beyond the horizon. Clouds of debris race around the planet and blot the Sun out for months. At least that's what theory tells us. he scenario has never played out in modern times, scientists don't really know exactly what will happen when the next space rock slams into Earth. One long-supposed incendiary side-effect is enhanced volcanic activity, which...

    Earth's volcanism linked to meteorite impacts 14:31 13 December 02 Exclusive from New Scientist Print EditionSpace rocks are blamed for violent eruptions (Image: GETTY) Large meteorite impacts may not just throw up huge dust clouds but also punch right through the Earth's crust, triggering gigantic volcanic eruptions. The idea is controversial, but evidence is mounting that the Earth's geology has largely been driven by such events. This would also explain why our planet has so few impact crater remnants. Counting the number of asteroids we see in the sky suggests that over the past 250 million years, Earth should have...

    Multiple comet impacts around 1500 years ago triggered a "dry fog" that plunged half the world into famine. Historical records tell us that from the beginning of March 536 AD, a fog of dust blanketed the atmosphere for 18 months. During this time, "the sun gave no more light than the moon", global temperatures plummeted and crops failed, says Dallas Abbott of Columbia University's Lamont-Doherty Earth Observatory in New York... Now Abbott and her team have found the first direct evidence that multiple impacts caused the haze. They found tiny balls of condensed rock vapour or "spherules" in debris inside...

    Double impact may have caused tsunami, global cooling Pieces of a giant asteroid or comet that broke apart over Earth may have crashed off Australia about 1,500 years ago, says a scientist who has found evidence of the possible impact craters. Satellite measurements of the Gulf of Carpentaria (see map) revealed tiny changes in sea level that are signs of impact craters on the seabed below, according to new research by marine geophysicist Dallas Abbott. Based on the satellite data, one crater should be about 11 miles (18 kilometers) wide, while the other should be 7.4 miles (12 kilometers) wide....
