Mark Olson with Advanced Geoscience, Inc. will speak about some interesting applications of seismic reflection, refraction, and MASW profiling his company has recently been involved with. These include fault investigations from Lake Elsinore to Goleta, investigations of subsurface geology for tunneling projects in Solvang and San Francisco, and shear-wave velocity profiling for earthquake response modeling of a new bridge abutment on Hawaii. His discussion will emphasize the geologic interpretation of these seismic profiles (such as, recognition of seismic reflection stratigraphy and structure), current methods of data processing and modeling, and the general resolution and accuracy of these methods for solving subsurface problems in engineering geology. If time permits, Mr. Olson will also discuss anticipated future improvements in near-surface seismic data acquisition and processing.
Mark Olson is President of Advanced Geoscience, Inc. a geophysical consulting firm located in Palos Verdes Estates, California. Mr. Olson has 25+ years experience in subsurface geology and applied geophysics, which includes four years of involvement with subsurface investigations for the construction of the Los Angeles Metro Red Line. He was formerly a senior geophysicist with Mobil Oil Exploration and Producing Services in Dallas, Texas, Project Hydrogeologist with Groundwater Technology, and Senior Geologist/Geophysicist with Dames and Moore in Los Angeles. Mr. Olson received his B.S. in Applied Geophysics from UCLA and completed numerous graduate courses at the University of Texas at Dallas and California State University, Long Beach. He is also a California-Licensed Professional Geophysicist and Geologist, and Certified Hydrogeologist.
