Alaska Amphibious Community Seismic Experiment

Lead PI: Dr. Spahr C. Webb

Unit Affiliation: Seismology, Geology & Tectonophysics, Lamont-Doherty Earth Observatory (LDEO)

August 2017 - July 2020

North America ; Alaska
Project Type: Research

DESCRIPTION: North America’s largest recorded earthquakes and largest documented volcanic eruptions both take place in southwest Alaska. A major shoreline-crossing community seismic experiment commenced in 2018, focused on the Alaska Peninsula subduction zone. Alaska is a GeoPRISMS primary site and current EarthScope target. The deployment is augmented by deployment of EarthScope Transportable Array (TA) seismic stations, earthquake and volcanic monitoring networks, and the recent development of a large pool of ocean bottom seismographs (OBSs). Together, these resource provide a unique opportunity to advance understanding of Alaska and subduction processes generally.
