Seismology in Alaska: earthquakes, bears, and high-performance computing

Seismology in Alaska: earthquakes, bears, and high-performance computing

Event Type: 

  • Seminar

Venue: 

ASE 3D Visualisation Laboratory (N2-B1c-16c)

Date: 

3 May, 2019 - 16:00 to 17:00

About the Event: 

Alaska is one of the world's prolific producers of earthquakes, including the 2002 magnitude 7.9 strike-slip earthquake on the Denali fault, the 1964 magnitude 9.2 subduction earthquake on the Alaskan megathrust, and the recent 2018 magnitude 7.0 earthquake below Anchorage. Earthquakes occur throughout the state and are a reminder of the active subduction, collision, and faulting that have shaped the highest mountains in North America. Over the past five years, seismic stations have been deployed in some of Alaska's most inaccessible regions. New seismic data provide opportunities to characterize new fault zones and to image complex subsurface structures, from the underlying Pacific slab to sedimentary basins within the crust. Complex structures produce complex earthquake ground motion that can be modeled using high-performance computational resources. I will discuss new seismic deployments, discoveries, and scientific frontiers in Alaska.

About the Speaker: 

Carl Tape

Carl Tape is a seismologist the University of Alaska Fairbanks. He develops and applies techniques in computational and observational seismology to obtain better images of Earth's internal structure and to obtain better representations of earthquakes. Improved seismic images of the crust and mantle provide an important snapshot of a dynamic Earth, and they can be used for scenario earthquake simulations that help assess seismic hazard in earthquake-prone regions. Dr. Tape received his B.A. in physics and geology from Carleton College, a M.S. from Oxford University, and a Ph.D. from California Institute of Technology. He did postdoctoral research at Harvard University before starting as faculty at UAF in 2010.
