About Induced Seismicity And The Natural (Geologic) Environment

The Tiampo group uses InSAR (Interferometric Synthetic Aperture Radar) to study the surface deformation associated with induced seismicity. InSAR time-series analysis, achieved through a collection of interferograms covering the same area, can be used to study the spatiotemporal relationship of the surface deformation in relation to well location and its injection volume, strengthening the link between the culprit injection wells and the induced seismicity and shedding light on the potential fluid pathways and the activated faults.

Graduate student Magali Barba studies tectonic and anthropogenic ground deformation using satellite radar. Before coming to CU for her PhD in Geophysics, she studied small-scale deformation following tectonic earthquakes as a graduate fellow at NASA’s Jet Propulsion Laboratory.
Dr. Tiampo is a Professor of Geological Sciences and the Director of the Earth Science and Observation Center at CU.  She studies earthquake seismicity and geodesy and their illumination of the physics of fault networks, including research into innovative techniques for InSAR and continuous GNSS data analysis.  The results from these studies have been incorporated into computational models of spatial and temporal seismic signals, groundwater deformation and volcanic processes around the world.  Significant contributions from her research group include development of the first of a new generation of seismicity measures, originally published in the early 2000’s; the incorporation of gravity signals into large-scale numerical fault simulation models; ongoing analyses of GNSS network data from eastern Canada and the western United States; and development of a more accurate method  for time-dependent InSAR analysis for the identification of surface deformation associated with earthquake and volcanic hazard as well as anthropogenic signals.
