When the JDF goes all hell is going to break loose in the NW. The only question for Seattle is whether it sinks into the sea, is flattened by the Tsunami or raises up out of the sea and is flattened by the earthquake (or a combination of all three). The other question is whether the earthquake awakens Ranier, Hood, Shasta, Lassen or St. Helens.
Well, thanks for ruining MY day! Many predictions that when JdF goes, it could very well be the biggest earthquake in recorded history, since it is a subduction fault. Unlike faults like San Andreas, which are slip/slide, this means that it will literally have to lift up a mountain range (the Olympic Peninsula in WA) and probably an island (Vancouver Island) a centimeter or so when it pops. That’s heavy lifting and a whole lot of shakin going on!
Subduction leads to Orogeny!
