[O]ver the last two weeks, about a dozen survivors of the quake — a magnitude 7.8 or 7.9 on the modern earthquake scales that struck at 5:12 a.m. on April 18, 1906 — have been made into centennial celebrities, shuttled from opening day celebrations at the ballpark, media-frenzy lunches downtown and Tuesday morning's painfully early breakfast with Mayor Gavin Newsom.
All of which is fun, most survivors say, but also taxing for a group of people whose claim to fame is somewhat dampened by the fact that they do not really remember the event in question.
NPR has a lot of interesting stuff on the quake. The story on rebuilding Chinatown is particularly good.
The USGS recreates the ground motions of the quake.
