Inside of a century, the Pacific Northwest could be struck by a magnitude 9 quake, shaking the region 10 times more violently than San Francisco's famous 1906 quake and for 12 times longer.

Scientists call it a "mega-thruster" and say the Seattle area is especially vulnerable.

The city rests on enough loose, liquefiable dirt to swallow Mount Everest, and the downtown straddles the Puget Sound area's largest fault.

"It lives in people's back yards," said geophysicist Tom M. Brocher, co-chief of Pacific Northwest Earthquake Hazard Investigations for the U.S. Geological Survey in Menlo Park.

What a coincidence! I just came across this article yesterday. Although I dont think that this 6.5 means it is a precursor to a monster quake, it is an odd coincidence. I also read an article on Saturday that stated the threat assessment level would not go up in the foreseeable future, so who knows...

Monster shaker foreseen
