(Cross-posting this from my more sciencey blog).
If your computer has an accelerometer, you can join the early warning network. With the ongoing seismic activity inland from San Diego recently I would hope folks in San Diego and Imperial Counties would be motivated. NPR has an article about it here. Among laptops, Lenovos and Apples both have accelerometers, maybe others too. Right now only 1,000 people around the world have this installed but the goal is to get at least 10,000 just in California. This is better than the post-quake "Did you feel it?" maps because it has the potential to give us a few extra seconds and save lives. Come on! It's more useful than SETI! Here's a link straight to the program itself.
Plus I bet it's way better than toads.
