WebNov 24, 2012 · A series of mega-tsunamis were generated by the bolide impact that created the Chesapeake Bay impact crater, about 35.5 million years ago. The mega-tsunami is believed to have over-topped the Blue Ridge Mountains (1,000 plus feet). Approximately 8,000 years ago, a massive volcanic landslide off of Mt. Etna, Sicily caused a mega … The Chesapeake Bay impact crater is a buried impact crater, located beneath the mouth of Chesapeake Bay, United States. It was formed by a bolide that struck the eastern shore of North America about 35.5 ± 0.3 million years ago, in the late Eocene epoch. It is one of the best-preserved "wet-target" impact craters … See more During the warm late Eocene, sea levels were high, and the tidewater region of Virginia lay in the coastal shallows. The shore of eastern North America, about where Richmond, Virginia is today, was covered with thick See more The continual slumping of the rubble within the crater has affected the flow of the rivers and shaped the Chesapeake Bay.
