PNW Earthquake: How big would be the "Big One?"

[Putting a massive Pacific North West earthquake in perspective:]

The Nisqually Plate, beneath south Puget Sound, slipped about SEVEN INCHES in 2011, triggering a quake that brought down building fronts in Pioneer Square, damaged the Capitol dome in Olympia, and set us on a path of replacing the Alaskan Way Viaduct. The pricetag: $2 billion.

The Juan de Fuca Plate, off the Coast, may slide as much as 14 to 15 FEET.

The Big One is very likely to be catastrophic.

For instance, there is one road off Washington's Long Beach Peninsula,... residents would have at most one hour's warning to evacuate.
