This subduction zone is know as Aleutian-Alaska megathrust zone (Sokolowski). This region was known for its active plate tectonics, but this earthquake did come as a surprise to the public and scientists in the area. About 200-250,000 kilometers squared of the earths crust were vertically displaced during the 1964 earthquake reports Carla Cornibert (Cornibert). The dominant stress that caused that much crust to be displaced was compression of the Pacific plate subducting below the North American plate. As the Pacific plate subducted below the North American plate pressure started to build causing compression and finally so much compression had built up causing elastic strain......
