"Oregon and Washington coasts will have only 30 minutes or so before a tsunami hits, when the subduction zone quake scenario in that region plays out as anticipated someday."

I was reading an estimation that, depending on placement, depth and probably other conditions, it could be 10 minutes or less before a tsunami hit the OR/WA coast after a quake.

Having spent many hours on Oregon beaches myself, I wonder if a person would actually feel a quake in the sand? I have warned my sister (new to the PNW) that if she did feel a quake, or saw a coastal draw-down, not to wait for anything, just to RUN. That's not the time to collect your belongings!
