Ground truth May 30, 2009
"An accretionary prism is simply the deep sea sediments that were deposited on top of the ocean floor and then rafted towards the subduction zone by plate tectonics," explains Harold Tobin. "As that happens, the plate that's on top - in this case the Japanese islands - simply scrapes that layer of sediment and rock off like it was the blade of a bulldozer. "The reason it's important is that the uplift of the sea floor, which causes the tsunami, is actually determined by the shape and geometry of... (BBC News -- Science)
