As a consultant, I focused on geologic and seismic hazard assessment of infrastructure, particularly pipelines. Geologic hazards include:
- Landslides and other slope stability issues
- Fluid withdrawal ground subsidence
- Underground mine collapse
- Seismic ground shaking
- Fault rupture of the ground surface
Most of these assessments include analysis of LiDAR topographic data and aerial photography, aerial reconnaissance, and traditional boots-on-the-ground fieldwork. These projects also include building and maintaining large GIS geodatabases to inventory and analyze hazards.
I also work on projects that include fault characterization and probabilistic fault displacement hazard assessment (PFDHA). Recently I worked on a project to characterize many of the major faults in the San Francisco Bay area and estimate their displacement across critical lifelines.
I am currently a licensed professional geologist in Idaho and Washington.
