I know you didn't "feel" it; but did you "see" it? Yesterday's newspapers carried articles highlighting the great earthquake in 1906. Next month - April 18th at 5:12 a.m. - to be exact, will be the 100th Anniversary of the San Francisco Earthquake. These articles reported how the USGC (United States Geological Survey) has created a web site where you can see map-view snapshots and movies illustrating ground motions. Talk about an educational application of ICT - WOW! The 3-D geologic map and seismic velocity model tell the story of this historic event in a way that you'll understandwhat really happened.
Although the movies and snapshots cover a 70 by 155 mile area, you can even move in for a closeup view of the shaking at specific locations in the Bay Area, for example: Concord, Palo Alto, San Jose, and Tomales Bay. On the ShakeMap, there is a "bright red region" (about 40 miles NNW of the epicenter) that highlights the region around Santa Rosa.
