I'm not sure where they are getting their 1 in 3 number, but it is true that the Cascadia Subduction Zone is the only major subduction Zone on the entire Pacific Ring of Fire not to receive a major earthquake in the last 50 years. So it is likely the Pacific Northwest is getting closer to it's next Major one.

I’d say this is credible, especially since these fault lines basically have to have earthquakes along their whole face to keep the tension under control.

If it happens in the south, it will also happen in the north.
