Faculty Dr. Laura Levy Geology Dr. Laura Levy, in collaboration with 11 co-authors, published “Multi-phased deglaciation of south and southeast Greenland controlled by climate and topographic setting” in the journal Quaternary Science Reviews. This comprehensive study tracked the timing of retreat of the Greenland Ice Sheet since the last ice age in an area of Greenland that is especially sensitive to climate change.

Student Tammy Phrakonkham Geology HSU geology student Tammy Phrakonkham has been selected to represent northern California at the 2019 Geosciences Congressional Visits Day (GEO-CVD) on Sept. 10-11 in Washington, D.C.
GEO-CVD is sponsored by American Geophysical Union along with other Earth science societies each year “to increase the visibility of and support for the geosciences in Congress.” During this event, participants will be given an opportunity to meet with members of the congressional delegation representing their state and with staff from congressional committees who have jurisdiction over issues related to geoscience.

Faculty Tyler Ladinsky, Harvey Kelsey, Melanie Michalak Geology Tyler Ladinsky (MS ’12), Harvey Kelsey and Melanie Michalak were awarded a one year grant through the National Earthquake Hazards Reduction Program to conduct a paleoseismic investigation on the Little Salmon Fault in Humboldt County. Their proposal, “In Southern Cascadia, Do Upper-Plate Faults Rupture in Concert with Subduction Zone Earthquakes: A Paleoseismic Investigation of the Little Salmon Fault Zone” is a collaborative effort between HSU faculty and students, the California Geological Survey, and United States Geological Survey to evaluate the chronology and style of earthquakes on the Little Salmon Fault in context of the Cascadia Subduction Zone.

Faculty Jasper Oshun, Margaret Lang Geology Geoscientists Without Borders funded a two year $100k project to complete a sustainable water project in the highlands of Perú. Jasper Oshun and Margaret Lang will lead a small group of students to Perú next summer to map the geology, explore surface runoff patterns and learn novel shallow geophysical techniques to determine the extent of the aquifer. These data will be used to design a water reservoir and agricultural canal system. They will return in the summer of 2019 to support the community in the construction phase. The canal will allow for year round agriculture, directly benefitting over 120 families.

Faculty Dr. Jason R. Patton Geology Dr. Jason R. Patton was invited to and participated in the research cruise CASEIS16. The goals of this cruise were to characterize the tectonics of the convergent subduction zone plate boundary along the Lesser Antilles in the equatorial Atlantic Ocean. Dr. Patton provided essential advice to the chief scientist Dr. Nathalie Feuillet for cruise planning by helping Dr. Feuillet locate core sites; locate seismic profile locations; describe, sample, and archive sediment cores; and conduct preliminary stratigraphic analyses. Dr. Patton provided expert advice on the methodology of turbidite paleoseismology.

Faculty Dr. Jason R. Patton Geology Dr. Jason R. Patton is a recipient of the Geological Society of America’s (GSA) Kirk Bryan Award, granted by the Quaternary Geology and Geomorphology Division. This is one of the most prestigious awards granted to geologists that study the Quaternary (from 2.56 million years ago to present).

Dr. Patton was a coauthor to the Goldfinger et al., USGS Publication, “Turbidite Event History—Methods and Implications for Holocene Paleoseismicity of the Cascadia Subduction Zone.” The award is presented to all coauthors.

The award will be presented at the September 2016 GSA national meeting in Denver, CO.

Faculty Brandon Browne, Raul Becerra Geology Brandon Browne and Raul Becerra (‘16) presented research at the Geological Society of America Cordilleran Section meeting in Ontario, California April 5-7. Their research project focused on understanding the origin and eruption of volcanoes on the Kern Plateau in the southern Sierra Nevada.

Faculty Melanie Michalak Geology Melanie Michalak, Assistant Professor of Geology, recently published a paper with co-authors in the peer-reviewed, Geological Society of America journal “Lithosphere.” The paper, entitled “(U-Th)/He thermochronology records late Miocene accelerated cooling in the north-central Peruvian Andes,” investigates the relationship between large-scale tectonics and long-term climate changes reflected in the morphology and rock uplift of the Peruvian Andes Mountains. doi:10.1130/L485.1

Faculty Lori Dengler Geology Geology Professor Lori Dengler has been named Chair of the California Integrated Seismic Network (CISN) Advisory Committee. CISN is the system that integrates the data inputs from the USGS, California Berkeley Seismological Laboratory, Caltech Seismo Lab, and the California Geological Survey into a seamless interface for rapid dissemination of earthquake information to a broad spectrum of users. CISN software packages are designed for first responders, emergency managers, and critical lifeline organizations. In the next decade, CISN will be taking the lead in implementation of California’s Earthquake Early Warning System. More information about CISN is at

Alumni Jonathan Castro Geology HSU alum Jonathan Castro (‘93, Geology) recently co-authored a paper that provides scientists with the first direct insight into the rocky lava known as obsidian flow. Castro, a professor at the University of Mainz in Germany, captured footage and images of a volcanic eruption in Chile in 2012. He and his colleagues found that contrary to popular belief, the lava kept moving more than a year after the eruption. The findings were published in recent issue of Nature Communications.

Staff Harvey Kelsey Geology Harvey Kelsey, a research associate in the Geology Department, has been named a fellow of the Geological Society of America. Honorees are nominated by existing GSA Fellows for their contributions to the geosciences. Contributions may include publications, applied research, teaching, administration of geological programs, public education, editorial, bibliographic and library responsibilities.

Kelsey was honored for using field investigations of coastal environments to make important contributions to our understanding of the history and processes of great subduction zone earthquakes and tsunamis in Cascadia, Indonesia, New Zealand, and Japan.

Student Erin Quinn Geology Erin Quinn recently accepted a Smithsonian Graduate Student Fellowship at the National Museum of Natural History. Erin will conduct high-temperature, high-pressure experiments on rocks from Chaos Crags, Lassen Volcanic National Park. Erin’s work will be the first experimental phase equilibrium study on Chaos Crags and will provide important constraints on magma storage conditions at Chaos Crags. This is important for better understanding the volcanic hazards within Lassen Park.

Student Kyle French Geology Geology professor Sue Cashman and Kyle French (’11, Geology) have received a mention in the third edition of Structural Geology of Rocks and Regions, a collegiate, structural geology textbook. The text explores the on-the-ground research conducted by undergraduates in Cashman’s structural geology class, as they assess damage to Ferndale Cemetery caused by the 6.5 magnitude earthquake that struck off the North Coast in January, 2010. In his senior thesis, French took that research further by comparing the directions of the toppled grave-site monuments to the likely direction of the seismic waves that caused the damage.
