Project Abstract
 In 2016 we completed our 4th year of SCEC-funded GPS observations in San Gorgonio Pass. Start-ing in summer 2013, we began observations at 23 new sites in San Gorgonio Pass and continued observations at another 11 sites we had previously observed in the pass. We also continued obser-vations at a number of sites in the San Bernardino Mountains and San Bernardino Valley. Velocities for most of the new sites now have uncertainties less than 1 mm/yr. Over past 4 years, ten SCEC interns have been supported to help with this project. In addition, 48 other undergraduate students, 1 master’s student, 25 high school and middle school teachers and 1 museum employee have partici-pated in the project over the past 4 years, supported by grants from the National Science Foundation and from NASA. Participants have presented 15 posters at SCEC and have given 3 oral and 5 post-er presentations at other professional meetings within the past 4 years.
Intellectual Merit The GPS site velocities computed from this work will be contributed to SCEC’s community geodetic model, which will help to constrain fault slip rates in the San Gorgonio Pass Special Fault Study Ar-ea.
Broader Impacts Over past 4 years, ten SCEC interns have been supported to help with this project. In addition, 48 other undergraduate students, 1 master’s student, 25 high school and middle school teachers and 1 museum employee have participated in the project over the past 4 years, supported by grants from the National Science Foundation and from NASA. Participants have presented 15 posters at SCEC meetings and have given 3 oral and 5 poster presentations at other professional meetings within the past 3 years.
