The Really Big One
An earthquake will destroy a sizable portion of the coastal Northwest. The question is when.
...........
If the entire zone gives way at once, an event that seismologists call a full-margin rupture, the magnitude will be somewhere between 8.7 and 9.2. That’s the very big one.
This quake was near the south end of the Cascadia Subduction Zone.
Hope this wasn’t a precursor to a “Full 9 Rip”.
(That’s what seismologists have nicknamed a full rupture of the Cascadia, producing an M9.0 all the way along it.)
