On Tuesday, July 15, 2008, 9:30 AM - 11:30 AM, Mr.Loren Turner presented "US Geological Survey ShakeCast."

The Division of Research and Innovation is currently working with the United States Geological Survey to develop and implement a Caltrans-specific version of ShakeCast, a post-event analysis tool that could ultimately lead to changes in the way Caltrans responds following a major earthquake. ShakeCast is a web-based application that, within ten minutes of an event, automatically retrieves measured earthquake shaking data, analyzes this against individual bridge performance characteristics, and generates inspection prioritization emails and other web-based products for responders.

Topic Description: "US Geological Survey ShakeCast"

Shortly  after  receiving  his  B.S.  in  Structural  Engineering  from the University  of California San Diego in 1993, Mr. Turner began his career with the California  Department ofTransportation. As a Civil Engineer working  in various Structures and Geotechnical branches, he has observed and worked  with contractors in the construction of major bridges and retaining walls  in  the  San Diego  and  the San Francisco-Oakland Bay Area.  He’s planned,   developed, and performed geotechnical insitu testing, pile load testing,  and solved significant problems associated with deep foundations; integrated  geotechnical instrumentation and data acquisition systems; and, designed  bridges  and  retaining  walls.  In 1999, Mr. Turner  joined the Division of Research &  Innovation  and  has  since led research efforts towards improvement of geotechnical practices within the Department. These efforts have included vibration studies, the applications of high precision Global  Positioning Systems to bridge and landslide deformation monitoring, development  of geotechnical information management systems, and earthquakenotification   technologies.  Mr.  Turner  completed  his  M.S. Geotechnical Engineering from the University of California Davis.
