  Role of Geotechnical Velocities in Shake Zone Scenarios in South Lake Tahoe

  The three major factors that control ground motion in an earthquake include: the source

  the geometry of the basin

  and the properties of the materials that the waves travel through. Using the Nevada Shake Zoning (NSZ) methodology developed by Dr. John Louie

  we studied the role of the geotechnical data set on the ground motion. For these models

  we analyzed the South Lake Tahoe Basin; specifically examining the impact of a rupture on the south end of the West Tahoe Fault. The South Lake Tahoe basin was of particular interest

  given its location on the western edge of the Basin and Range province and the large tourist draw of the area. The West Tahoe Fault has the largest vertical offset in the area and last ruptured approximately 4000 years ago (Brothers et. al. 2009). We sought to compare our limited geotechnical data set with more comprehensive but theoretical data sets. Our resulting scenarios generated PGV values of nearly 200 cm/sec. We also established that minor changes in Vs30 created amplifications of a factor of two and deamplifications of a factor of one-half. Our results imply that dense Vs30 measurements are necessary to fully understand potential hazards resulting from earthquakes in and around basins.

  and conducting a research program in geophysics. The goal of my research is to accurately image and characterize subsurface structures and conditions in seismically difficult areas

  with high-resolution experiments. I constrain these observations with independent geophysical and geological data. The seismic characterization

  imaging

  tomography

  and monte-carlo optimization techniques I develop improve the productivity of resource exploration and development

  and of hazards assessments. In particular I try to describe the characteristics of earthquake faults and of sites in order to mitigate seismic hazards to life and property; and to seismically image geothermal resources.
