Computed Tomography (CT) scans of sediment cores collected from Montague Island, AK

This data release contains Computed Tomography (CT) scan images of sediment cores collected from Montague Island, in Prince William Sound, Alaska. Sediment cores were collected from lagoons uplifted >3 m in the 1964 earthquake along the coast of Montague Island and aid in interpreting changes in deposition environment over the past several thousand years, which may record evidence for past episodes of earthquake uplift. The 2017 USGS Subduction Zone Science plan includes the key priority to characterizing past hazardous events to forecast the future using onshore and offshore clues. Such clues include coastal evidence of sudden vertical land-level changes caused by large earthquakes along subduction zones.
