Odds are bugging in is the most likely option, regardless of whether you're in a flood zone or volcano zone.

If flood conditions force you out take the supplies you have for bugging in, pack the kids into your car and leave.

When's the last time a volcano poured lava in the PNW -- okay, it happens and it was pretty devastating but there was plenty of warning and again, pack your stuff and kids into the car.

Plan for the most likely problems and the most likely situations will probably have you staying home and bugging in.
