Caltech's Millikan Library in Motion

From the creator

Tall buildings "feel" earthquakes, even when their occupants don't. Caltech's nine-story Millikan Library has motion sensors on every floor, and here's what they recorded during the magnitude-4.2 Newhall earthquake on September 1, 2011. Note to the squeamish: the motions have been exaggerated by a factor of 100,000 relative to the size of the building. This video is adapted from "Earthquake Waves in Your Neighborhood," presented by Professor of Geophysics Robert Clayton at Caltech's 75th Annual Alumni Seminar Day on May 19, 2012.
