The plates along the Cascadia Subduction Zone make some sound as they grind and push up against one another [Edit: Apparently not for several decades, see the link in post #2]. This may suggest that intense pressure is building along the plates, which could be unleashed at any moment.
What is extraordinary is that all of Cascadia is quiet. It's extraordinarily quiet when you compare it to other subduction zones globally," Toomey said in an interview.
Which leads the researchers to conclude the dangerous Cascadia fault zone is stuck — or in science-speak, it is fully "locked."
The evidence pointing to the colliding tectonic plates being completely stuck has serious implications for earthquake risk on land in the Pacific Northwest.
Toomey described himself as "very concerned" and said it is "imperative" people in the Northwest continue to prepare for a big earthquake.
