The San Andreas Fault runs through Cajon Pass [lower left to upper right] in Southern California. See Lost Lake in the middle of the photo? Good place to bird — I saw a Purple Martin there last year. Photo by cocoi_m on Flickr.
A most excellent comment from geologist [specializing in tectonics] and science blogger Chris Rowan, on Twitter:
Anyone using the word 'overdue' automatically forfeits their right to be taken seriously.
Chris tells it: How to (and how not to) talk about earthquake hazards in the media. USGS seismologist Susan Hough, A+! Newsweek and "journalist" Simon Winchester, F- and dunce caps all around.
