Paleoseismology of the Southern Clark Strand of the San Jacinto Fault Zone, Southern California Michael Buga M.S. Candidate Department of Geological Sciences San Diego State University Advisors Dr. Tom Rockwell We present results from a new paleoseismic trench site on the Clark strand of the San Jacinto Fault Zone in Clark Lake, western Salton Trough, southern California. The trench results suggest that most late Holocene slip along the Clark fault at Clark Lake is localized within a...

Growth Dynamics in the Intertidal Barnacle Megabalanus: Development of a Subseasonal Paleoceanographic Archive Julio F. Morin ABSTRACT The arthropod Megabalanus coccopoma is indigenous to coastal Baja California, but migrated up to San Diego due to an El Nino event in the early 80s (Newman and McConnaughey 1987). Megabalanus dates back to the Miocene (Doyle et al. 2007) is a useful local indicator of exposure and submergence intervals due to their feeding habits which correlates to...
