10th Anniversary Of The Northridge Earthquake: Airtalk Goes To Caltech's Seismology Lab

A 6.7 magnitude earthquake woke Angelenos at 4:30 in the morning on January 17th, 1994. Called the Northridge Earthquake, it killed fifty-seven people and caused between $20 and $40 billion worth of damage. According to the US Geological Survey, the earthquake produced the strongest ground motions ever recorded in an urban setting in North America. "AirTalk" with Larry Mantle goes to Caltech's Seismology Lab to talk with experts about what we knew then, what we learned from the earthquake, and the latest advancements in the science of seismology. Joining him is Dr. Charles Groat, Director of the US Geological Survey, Dr. Tom Heaton, Professor of Engineering Seismology at Caltech, and Dr. Egill Hauksson, Senior Research Associate in geophysics at Caltech.
