Research

Current Research:

• Earthquake damage detection in buildings and early warning based on wave travel times
• Coherency of ground motion at short separation distances
• Generation of artificial ground motions by the SYNACC method – motions on an array of closely spaced points
• Scaling of strong ground motion
• Los Angeles and Vicinity Strong Motion Network
• Data processing (see The Strong Motion Data Processing Laboratory)
