“LONDON – The chain reaction that sent enormous, deadly tidal waves crashing into the coasts of Asia and Africa on Sunday started more than six miles beneath the ocean floor off the tip of the Indonesian island of Sumatra.
Geologic plates pressing against each other slipped violently, creating a bulge on the sea bottom that could be as high as 10 yards and hundreds of miles long, one scientist said.
“It’s just like moving an enormous paddle at the bottom of the sea,” said David Booth, a seismologist at the British Geological Survey. “A big column of water has moved, we’re talking about billions of tons. This is an enormous disturbance.”
Moving at about 500 mph, the waves took more than two hours to reach Sri Lanka, where the human toll has been horrific, and longer to spread to India and the east coast of Africa.”
Fascinating, just amazing.
