    Cascadia Megathrust earthquake? GPS stations along the coast of Japan had been moving to the west before the March 11, 2011 earthquake, and rebounded back to the east following the earthquake. This animation compares that subduction zone with a mirror-image subduction zone in the Pacific northwest by illustrating how the shallow portion of the Cascadia plate boundary is locked by friction thus compressing the overlying North American Plate in a NE direction during subduction of the Juan de Fuca Plate. Using a spring to emphasize the strain within the overlying plate, we will see the displacements of GPS receivers along the entire leading edge of the North America continental margin. Ultimately, the continental margin will rebound suddenly to the southwest as the stored elastic energy is released for the first time since the last great Cascadia earthquake on January 26, 1700

    What amazes me more than this superbly graphic presentation of the CSZ and it's dynamics, is the fact that it's gotten only 33 views! C'mon, people - don't wait for the government to fix what will happen once the CSZ lets go; y'all need to get engaged with the reality that this effects all 7 million of us up and down the NW coast, in a dire way.

    How earthquake resilient can you be if your swimming in the Pacific Ocean.

    Very great information. I feel time is running out before the CSZ finally ruptures. No one knows yet how much of the CSZ will rupture but stay prepared

    Wait, the motion is against plate tectonics.

    Why is there no trench for Cascadia?

      There is a trench hidden from view. It is filled with sediment.

    The Earth is Flat.
    Jesus will be appearing soon.
    Make sure you are ready.
