Our work in Alaska has focused on reconstructing earthquake and tsunami histories over the historical and prehistoric period, mainly in the Kodiak Island region within the overlap of the 1788 and 1964 CE ruptures. Our studies have focused on characterizing coseismic land-level change and tsunami inundation in the region, helping help place bounds on the along-strike extent of Alaska-Aleutian subduction ruptures, an earthquake recurrence model for the subduction interface of the Alaska–Aleutian subduction zone from geodetic and paleoseismic data, and characterizing the behavior of splay faults in the 1964 rupture area.
Our work in Alaska continues, with ongoing projects reconstructing coseismic land-level change and tsunami inundation in the Kodiak Island region, searching for elusive tsunami deposits in the Shumagin gap, and exploring the impacts of Alaska-Aleutian subduction zone tsunamis on distant shorelines under sea-level rise.
Collaborators on Alaska projects include Rich Briggs, Simon Engelhart, Rob Witter, Rich Koehler, Alan Nelson, Guy Gelfenbaum, Peter Haeussler
