Dr. Lisa Grant and Eldon M. Gath at UC Irvine.
Dr. Lewis A. Owen at Univ. of Cincinnati


Recent work on this project investigates the distribution, age and neotectonic significance of fluvial terraces along the Santa Ana River and Santiago Creek in the eastern Puente Hills and northern Santa Ana Mountains. The long-term goal is to assess the earthquake potential of the southern Los Angeles basin, an area that encompasses Orange County, CA.
