UC Davis is ranked as having the highest impact of any university in life and earth sciences when both research output and quality are evaluated (http://dateline.ucdavis.edu/ dl_detail.lasso?id=15201&dn=060915). In addition, our graduate program remains very highly ranked, and excellent students are choosing to study in our Sarah Roeske in the Alaska Range. department. Our Geology, Natural Sciences, and Marine and Coastal Another major shift in our research Science majors remain strong and are program is a “change of hats” by continuing to grow. Dr. Sarah Roeske. Sarah helped run and managed the Electron Microprobe Lab for 25 years, and she decided to I am very pleased to announce that retire from her staff position in 2015. Professor Nicholas Pinter has joined the She will remain active in research and Earth and Planetary Sciences faculty teaching within Earth and Planetary as the new Roy J.

“The culprit for the 2014 South Napa earthquake was the West Napa fault. As we later discovered, this is not the first time that this fault has damaged the wine industry.” – Mike Oskin

That May I submitted a proposal to the U.S. Geological Survey to study these features. This proposal would seem prescient a few months later.

I was not in Davis on August 22, the morning of the South Napa earthquake. In southern California, visiting family, I would learn of the event about 5 hours later. The existence of surface rupture was not yet confirmed, so I immediately began to scour the web for reports of road damage, and Twitter for photographs. These revealed right- lateral offset of Highway 121/12, west Rupture across South Avenue and adjacent vineyard.

The results of this effort were directed them to unexplored sites along of offset features from overlapping digital photos. By preserving the 3-D geometry of features, this technique enables reproducible post-earthquake measurements using a virtual environment such as the KeckCAVES. Of course they use LidarViewer to make these measurements. Angela Hawkins showed that the aftershocks of the 2000 Yountville event lined up with those from 2014, consistent with a single, larger earthquake source. Mary Barr and Justin Linderman used this information, along with our mapping, to generate a 3-D model for the greater West Napa fault, and to estimate Coulomb stress change on segments that did not rupture in 2014. Based on its size, the West Napa fault is capable of producing a ~M7 earthquake if it ruptured from end to end. This would be over 30 times the energy released in the 2014 event, Napa Valley Grist Mill historic site is built across 2m-high scarp of West Napa fault. and it would affect the entire length of Napa Valley. 5 EARTH AND PLANETARY SCIENCES FACULTY

After completing his doctoral degree, he became a celebrated teacher, specializing in general education courses that inspired and entertained thousands of undergraduates. His students—who adored him—bestowed on him the nickname “Moondude” for his love for planetary geology: a moniker he enjoyed greatly.
