Project Description: This project involves two components: 1) field work deploying and maintaining seismic sensors and 2) analysis of the seismic data. 

A temporary array of seismic sensors has been installed (with assistance of 3 previous undergraduates over the last two years) in the UCSB-managed Sedgewick Array, just south of Figueroa Mountain. These state-of-the-art seismic sensors record global and local seismicity. The seismic stations require regular maintenance and data extraction, and we use the sites to test techniques for seismic deployments. Fieldwork involves learning to interface with and configure the sensors, outdoor exertion (hiking, carrying equipment, clearing brush, digging holes/trenches), and in-field data evaluation. 
 
Nearly a year of high-quality seismic data requires analysis using a suite of data processing techniques to learn about the local Earth structure and seismicity. Teleseismic (distant earthquake) recordings can be used to compute crustal interfaces beneath the stations. Recordings of local seismic events (including non earthquake sources) and seismic noise tell us about regional earth processes, from seismicity to landslides to ocean storms. 
 

Undergraduate Contribution: Participating undergraduates  will participate in fieldwork activities to maintain and deploy seismic stations. Research analyzing data from the existing array will comprise an undergraduate senior thesis. 

Requirements and/or Application Instructions: Essential prerequisites include Earth 134, 135, 136 and 194ML or equivalent programming class conferring proficiency in MATLAB or Python. Earth 131, 133 also highly recommended.
