Earthquakes and Washington

This topic for N.P.R. was totally unplanned until an airing of "Inside Olympia" was showed on the TVW cable station, today, but they had an interesting show to remind us that we live in an earthquake zone of the world, sometimes referred to as the Pacific Rim of Fire, and that all of us should be prepared for a possible natural disaster emergency.  Particularly worrisome is the possibility of a great earthquake (N.P.R. can't recall the exact term that was used) as opposed to the "shallow" earthquake of 2001 that caused havoc in Washington, though few casualties.  They said the great earthquake could happen anytime, from now to 500 years from now, and that everybody should have an ample supply of food and water in reserve.  N.P.R. doesn't feel experienced enough to make any technical suggestions, but everyone should research for themselves and have a plan on where would be the best place for immediate safety during an earthquake.  Every city in Washington should have some kind of earthquake and/or tsunami preparedness plan at the ready.  By the way, "Inside Olympia" (channel 23) does a lot of re-runs within the same week, so this particular show might still be airing, and is probably on the internet as well.
