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 Melanie Michalak, Susan Cashman Geology Melanie Michalak and Susan Cashman (Geology) were awarded a 3-year, multi-institutional National Science Foundation grant, with Eric Kirby (OSU) and Kevin Furlong (Penn State), to study geologic deformation in the Klamath Mountains. This research addresses both mountain building (long term deformation) and crustal strain associated with megathrust earthquakes (short term deformation). Principal investigators and students will partner with Hoopa Valley Elementary School’s 6th grade teachers for research-related activities and field trips for HVES 6th graders. HSU was awarded $158,636 to support graduate and undergraduate students, 6th grade teachers, supplies, and analyses.

Faculty Mark Hemphill-Haley Geology Mark Hemphill-Haley (Geology) returned from two-week investigation of the 2016 M 7.8 Kaikoura earthquake, South Island, New Zealand. He joined HSU alumni Russ Van Dissen ('83) and Jessica Vermeer ('13 BS, '16 MS) and NZ researchers to investigate the deformation associated with more than 9 m (27 ft) of offset during the earthquake. The investigation involved trenching across the fault to assess fault structure and timing of previous earthquakes.

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 Melanie Michalak Geology Melanie Michalak was awarded a American Chemical Society- Petroleum Research Fund grant toward her proposed research, "Reconstructing Neogene Paleogeography and Forearc Basin Evolution of Southern Cascadia using Detrital Mineral Geochronology." The grant of $55,000 is awarded over a two year period and will support original research by PI Michalak, a MSc student and a team of undergraduates. Their work in the coastal deposits along the north coast seeks to characterize paleogeography and forearc development over the past several million years using quantitative dating techniques.

Faculty Brandon Browne, Raul Becerra Geology Dr. Brandon Browne, Associate Professor of Geology, and four undergraduate thesis students, including Raul Becerra ('16), recently published their study titled "Quaternary basaltic volcanism in the Golden Trout Volcanic Field, southern Sierra Nevada, California" in the Journal of Volcanology and Geothermal Research. The study uses results from geologic mapping and geochemical analyses of rocks and minerals to interpret the eruption styles and geologic evolution of the volcanic field - the only one of its age in the High Sierra.

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.
