Even more frightening is that experts predict a "mega-thrust quake" in the near future for the Pacific NW region of the US. This is the worst type of earthquake were a plate slides / buckles under another and thrusts pressure of course through the top plate. If this were to happen?...hard to imagine but it would be much more catastrophic than what Japan is dealing with. Being the likelihood of initially up to a verticle 30 meter separation in land mass...and then come the after affects? WTF!
That sounds like a normal subduction zone to me (which is exactly what Japan deals with).
So... yeah.
Associated Press said:David Applegate, a senior science adviser for earthquake and geologic hazards for the U.S. Geological Survey, said the 8.9-magnitude quake ruptured a patch of the earth's crust 150 miles long and 50 miles across.
