Lidar shaded relief map of the Hayward Fault and UC Berkeley stadium
A filtered vertical laser image, taken using a technique called light detection and ranging (LIDAR), of part of the Hayward Fault (red lines) in the City of Berkeley. The fault passes through the University of California Berkeley football stadium (left), and past earthquake movements have significantly offset Hamilton Gulch (center).
