Over his career, Aaron Velasco, PhD, has been fortunate to be able conduct a variety of seismological and interdisciplinary research studies, including earthquake source modeling, seismotectonics, earthquake hazards, earthquake interactions, 3-D Earth modeling, and nuclear treaty monitoring research (seismic event detection, location, and discrimination). Dr. Velasco current projects include: determining 3-D Earth structure from analysis of multiple data sets in Colombia; exploring techniques for joint inversion; studying aftershocks of large earthquakes in Nepal and Mexico; studying volcanic structure in the East African Rift System in Kenya; studying local earthquakes in the El Paso, TX region; and understanding the link between earthquakes, in particular, the mechanisms for dynamic triggering. Dr. Velasco also has projects that focus on educational aspects of science, including programs that fund early geoscience undergraduates to promote diversity in the geosciences. He also currently serve the State of Texas as the State Seismologist, which merges his technical expertise with science policy.
