More than one thousand Washington National Guard members are rehearsing a worst-case earthquake scenario this week. That would be a magnitude nine rupture of the offshore Cascadia fault zone. Adjutant General Bret Daugherty says he assumes quake relief in that case will need to be delivered by airlift from east of the Cascades.
"We're going to have large pockets of isolation because we're not going to be able to travel on the ground. So really, help is going to have to flow into Western Washington from the east. Spokane is going to play a critical role there," says Daugherty.
