A magnitude 6.5 earthquake could severely damage the San Francisco Bay Delta levee system and cut off vital water supplies for millions of Californians, according to experts at a May 10 press conference at Stanford’s Blume Earthquake Engineering Center. Martin McCann, consulting professor of civil and environmental engineering, and retired Brig. Gen. Gerald Galloway of the U.S. Army Corps of Engineers discussed their concerns about the integrity of U.S. levees in the wake of Hurricane Katrina.
