Using Satellite Imagery to Understand Structral Patterns Over Large Regions

Mary Hubbard, Ph.D.

Department of Geology

Dr. Hubbard has projects studying the structural geology in New Zealand, Senegal, and south-central Colorado. She made use of satellite imagery to understand structural patterns over large regions. The remote sensing work is coupled with field investigation and hand-sample analysis aimed at understanding details of the tectonic history of these regions. She engaged a graduate student in geologic mapping both with the satellite images and with field methodologies. Satellite imagery was coupled with new high resolution sea floor bathymetry to identiry fault geometries and to ultimately gain a better idea of the directions of fault block movement direction. The data was coupled with age determinations such that rates of slip were determined and related to the earthquake hazard of the region.
