The recent M5.3 earthquake in Colorado and M5.9 earthquake in Virginia serve as reminders that shallow earthquakes can happen away from known fault lines. The Cascadia Region has experienced many shallow historical earthquakes. A shallow earthquake on the Seattle or Portland Hills faults would result in widespread damage and disruption.
