The fault zone where the next big Pacific Northwest earthquake is expected to occur lies 40 to 80 miles off of the Pacific Northwest coast. The area is called the Cascadia Subduction Zone.
Accordingly, earthquake scientists have put listening posts along the coast from Vancouver Island to Northern California.
Now, the seismometers have gone eerily silent. Typically, there is noise from the plates coming in contact with each other.
University of Oregon geophysics professor Doug Toomey labels it a “a puzzle” and says: ” What is extraordinary is that all of Cascadia is quiet. It’s extraordinarily quiet when you compare it to other subduction zones globally.”
