For several days, a rumor has been spreading wildly over the internet, compliments of Twitter and Facebook. It started with a tweet that claimed Caltech was sending employees and students home because seismologists were predicting a major earthquake was about to hit the Southland. Caltech and the U.S. Geological Survey were flooded with concerned calls, but the whole thing was a hoax – Caltech scientists say it’s impossible to predict earthquakes and no one was sent home. Why do rumors like this take off? What's going on in our heads? And is social media one giant rumor mill?
