Three hours ago we had a magnitude six earthquake about 200 miles west of the Oregon coast near the 90 bend in the Juan De Fuca / Pacific Plate interface.  There were three 5+ magnitude quakes, in addition to this one, in the last 24 hours near this same area.  This subduction zone is what is known as the Cascadia fault.  The deeper parts of the subduction interface are semi-fluid and move with a slow creep but the shallower portions lock and release suddenly, and when they do, can generate anywhere from an eight to as high as ten magnitude Earthquake and given that when that fault moves, it changes the altitude of the land below the ocean, it is guaranteed to generate a tsunami.

     The media is saying these quakes aren’t related to the Cascadia fault, but given they are located right where the locked portion of the subduction zone is, I don’t see how they can say that other than flat-out lying.
