Friday marks anniversary of great Pacific Coast quake, tsunami

Friday marks the 318-year anniversary of one of the greatest earthquakes on record along the Pacific Coast - the estimated 9.2 "Cascadia" quake that struck just off our coast on Jan. 26, 1700. To coincide with the anniversary, NOAA and the Pacific Tsunami Warning Center have released a computer model depiction of how the devastating ensuing tsunami raced across the Pacific Ocean.
