Major quake strikes off coast of Northern California

AP is reporting a 7.0-magnitude earthquake struck minutes before 8PM off the coast of California near the California-Oregon border. A tsunami warning is in effect from the California-Mexico border all the way north to Vancouver Island, British Columbia. Residents were being evacuated from low-lying areas of Crescent City, KCBS radio reported.

Just this Monday The San Francisco Chronicle reported on the work of UC Santa Cruz scientist geophysicist Steven Ward who, spurred by the tragedy of December’s great Sumatra quake and tsunamis, estimated the heights that a similar quake-spawned tsunami would reach on the West coast. Ward estimates the ensuing tsunamis from a 9.0 earthquake would hit the the shores from British Columbia as far south as the tip of Baja California at heights equal to or greater than those recorded in the Sumatra quake. Ward’s graphic can be seen here, and in an eerily timed accompanying picture, damage from Crescent City’s last tsunami is shown as well.

USGS has a map of the quake area overlaid with the intensity level reported by residents.
