This is the fourth segment of The Infrastructure Show podcast series, with Host Professor Joseph Schofer, Director of Northwestern University's Infrastructure Technology Institute, and Co-Host Tom Herman of Vocalo.org. Two earthquake and dam experts from Northwestern University in Evanston, IL -- ­ Dr. Seth Stein, William Deering Professor of Earth and Planetary Sciences and Dr. Charles Dowding, Professor of Civil and Environmental Engineering -- ­ talk with the hosts about the magnitude 7.99 Wenchuan Earthquake that occurred in China on May 12, 2008, and the possibility that this earthquake was triggered by the operations of the nearby Zipingpu dam and its reservoir. They expand the discussion to include other examples of suspected dam/reservoir-triggered earthquakes, offering their thoughts on the benefits and risks of dam locations, and the ability of structures to withstand ground movement.
