Intellectual Merit
|
The contributions of this project aree threefold. Firstly, we have placed firmer constraints on surface velocities of critical sites that have, in several cases, only been surveyed twice in the past ten years, data that can be incorporated into future versions of the SCEC Crustal Motion Map. Secondly, the data will allow further testing of some of the models used in the UCERF2 analysis and the conclusions drawn from them, and help to refine our understanding of the seismic hazard on the northern San Jacinto fault. Finally, by updating the archive of GPS data for the San Jacinto fault, we have improved the temporal resolution of the archive, which would be beneficial for measurement of coseismic displacements and/or postseismic transients for a future earthquake on the fault. |

Broader Impacts
|
We anticipate that our processed GPS data and models built upon them will also assist with comprehensive efforts in seismic hazard assessment, such as current and future versions of the Uniform California Earthquake Rupture Forecast, a project that has considerable benefits to society.
The project involved a SCEC SURE intern, Sarah Morton, who was tasked with planning and executing collection of the GPS, plus their archiving and processing. We have successfully addressed the SCEC objectives in Education and Outreach, to "interest, involve and retain students in earthquake science" (SCEC CEO Focus Area Objective E2) - Sarah will be starting graduate school in a related field in the Fall. |
