There was an earthquake near Yucaipa today around 1:54 p.m. This link will take you to the USGS (U.S. Geological Survey) event site. There's a link there called "Did you feel it? Tell us." They're trying to collect experiential data from people who felt anything. There's also a further link if you want to supply data about the 1994 Northridge quake. I'm enough of a science geek that I find this stuff fun. So if you'd like to help them out, just follow the links.
