Research Interests
Dr. Andrew Lamb’s research interests are in the application of gravity and magnetic geophysics to solve geologic and tectonic problems that range from earthquake hazards to geothermal energy exploration and development.
Current Research Projects
His most recent postdoctoral research focuses on the use of aeromagnetic and gravity data, constrained by seismic and geological mapping, to help determine the extent of geologic structures and earthquake hazards in the Columbia River basin.
Develop unconventional aeromagnetic acquisition methods, in areas inaccessible to traditional fixed wing airborne surveys, to investigate the relationship between the Cascadia convergent margins back-arc and forearc tectonic connections. These tectonic links are poorly understood and likely play an important role in hazard assessment for the region.
Develop methodologies that use micro-seismicity earthquake data to help constrain structural models derived from magnetic and gravity data.
Creation of a three-dimensional geologic and structural model for the Cascadia fore-arc and back-arc to compare with other global analogous fore-arc and back-arc connections.
