Crossing the San Andreas Fault: Improving the Resilience of the Los Angeles Aqueduct System
Crossing the San Andreas Fault: Improving the Resilience of the Los Angeles Aqueduct System
Scott Lindvall - 2019-2020 Jahns Distinguished Lecturer
Scott Lindvall - 2019-2020 Jahns Distinguished Lecturer
This talk focuses on the Los Angeles Aqueduct crossing of the San Andreas fault in the Elizabeth Tunnel and describes the detailed surface and subsurface geologic investigations used to characterize the architecture of the fault zone at tunnel depth. Historic fault displacement data from world-wide strike slip faults are presented along with fault displacement hazard analyses performed to address the new 2019 performance-based seismic design guidelines for the Los Angeles Department of Water and Power.
Speaker Biography
Speaker Biography
Scott received his BS in Geology from Stanford University in 1984 and his MS in Geology from San Diego State University in 1988. Dick Jahns was Scott’s undergraduate advisor at Stanford, which makes this award especially meaningful to him. He has spent the majority of his career working for consulting firms specializing in seismic hazards and engineering geology. He currently manages the Lettis Consultants International southern California office, and prior, worked many years at both William Lettis & Associates, and Lindvall, Richter & Associates.
His interest in geology came at a young age growing up in the Transverse Ranges of southern California. His geologist father, Eric Lindvall, helped instill an appreciation of the outdoors (and therefore geology) and was later instrumental in shaping Scott’s career. His interest in earthquakes was triggered at nine years old in the early morning hours of February 7, 1971 with the M6.6 San Fernando earthquake. Experiencing strong ground shaking from the main shock and several large aftershocks in the epicentral region, while dust was slowly rising from rock falls in the surrounding canyons, left a lasting impression.
