Brian is a geologist who specializes in field studies of earthquake-generated land-level changes and other deformation recorded in the geologic record. His focus is on coastal environments in subduction zone environments.
Dave is a field technician for the Pacific Northwest Seismic Network. He installs and maintains seismic field instrumentations, mostly in the Puget Sound area. His motto is "I’m safe, working to keep you safe."
Art is a seismologist with expertise in the observation and modeling of earthquake ground motions. Most recently he has focused on understanding and modeling the rupture and consequent shaking resulting from great, M>8 subduction zone earthquakes.
Joan is a research geophysicist, specializing in earthquake seismology. Her research focuses on how earthquakes initiate and affect one another, the different ways in which faults slip, and earthquake-triggered phenomena in submarine and other environments. Joan works with emergency managers, engineers, and others in the community, and has been engaged in efforts to enhance subduction zone science.
Ralph is a structural geologist, with particular expertise in using satellite and other remote imagery to map and interpret geologic processes, primarily in Cascadia. He also studies the interactions between glaciation and geologic processes over geologic time scales.
Tim manages many aspects of the computer systems that underlie the Pacific Northwest Seismic Network operations, particularly those involving Linux and Unix operating systems.
Kris is a staff scientist in the USGS Natural Hazards Mission Area and an affiliate assistant professor in the Department of Earth and Space Sciences at the University of Washington. She is part of the Department of the Interior Strategic Sciences Group (SSG), which was created in 2012 to support decision making during environmental crises affecting Departmental resources. Kris has co-authored the USGS’s “Reducing Risk Where Tectonic Plates Collide – A Plan to Advance Subduction Zone Science” and “Science for a risky world— A U.S. Geological Survey plan for risk research and applications”.
Colin coordinates activities related to the development of Earthquake Early Warning for USGS in the Pacific Northwest, which is part of the west coast-wide ShakeAlert EEW system. He is currently working to get ready for a limited release of the ShakeAlert system, as well as managing day to day EEW-related operations.
Brian Sherrod (PNW Coordinator)
Brian is a geologist and is the Coordinator of the USGS’s Pacific Northwest Earthquake Hazards Program. His research focuses on characterizing faulting histories from the geological record uncovered in trenching and geomorphic studies, particularly for crustal faults. His recent work has examined earthquake hazards in eastern Washington, and the Olympic Peninsula.
Lynn is a field technician for the Pacific Northwest Seismic Network. She also is responsible for testing and tuning many of the PNSN’s data acquisition systems, and the databasing of much of the metadata.
Erin’s research focuses on earthquake hazards, specifically in subduction zone settings. She is currently using 3-D numerical simulations to predict earthquake ground motions associated with large (i.e., magnitude 9) earthquakes in the Cascadia subduction zone, and more generally is studying the generation of strong ground motions by distinct patches on the megathrust (i.e., as observed in the 2011 M9.0 Tohoku, Japan earthquake) and the amplification of ground motions by deep sedimentary basins (e.g., the Seattle basin). She works closely with engineers and social scientists to improve earthquake resilience in the Pacific Northwest.
Tom is seismologist who helps run many of the operational aspects of the Pacific Northwest Seismic Network Seismic Network, in collaboration with the University of Washington.
Brett is a technician and engineer, responsible for construction of many of the field site equipment and for management of meta-data related to data acquisition.
