Descr: This project is designed as a hands-on training and educational experience for undergraduates and graduate students in the Department of Geosciences with the goal of encouraging scientific investigations using controlled-source seismic techniques. The target of the study is the Pitaycachi fault zone in northern Mexico (south of Douglas, AZ), which last ruptured with a magnitude 7.3 earthquake in 1887. Students will have an opportunity to collect high-resolution reflection data across this fault zone to help characterize the subsurface geometry of the fault and perhaps evaluate previous fault movements. This work will be incorporated into class discussions and independent-study exercises and and may serve as a pilot study for additional future work.
