Summary

This dataset provides a digital elevation model mosaic derived from airborne lidar data acquired in 2018 from September 2–3 over eight separate areas along Alaska's Montague Island coast, between Prince William Sound and the Gulf of Alaska.

Purpose

During the 1964 Great Alaska earthquake (magnitude 9.2), several megathrust splay faults including the Patton Bay Fault beneath Montague Island ruptured, raising the island by up to 10 meters and producing tsunami waves. These lidar-based digital elevation models facilitate detailed geomorphic study of the coastal landscape resulting from the 1964 earthquake, and from island uplift during ancient earthquakes. These studies characterize earthquake location, recurrence, and magnitude, and will contribute essential information to the U.S. Geological Survey National Seismic Hazard Map.
