Summary

This dataset provides four digital elevation models derived from airborne lidar data acquired over four separate areas along and adjacent to the Fairweather Fault along the remote Gulf of Alaska coast within Glacier Bay National Park. In 1958, the Fairweather Fault in southeast Alaska ruptured over 260 km between Yakutat Bay and Cross Sound, producing the magnitude 7.8 Lituya Bay earthquake. To better understand the extent of surface rupture and identify sites to investigate for evidence of past earthquakes, the USGS Alaska Science Center collaborated with the National Park Service, the Army Corps of Engineers' Cold Regions Research and Engineering Laboratory (CRREL), and the National Center for Airborne Lidar Mapping (NCALM) at the [...]

Purpose

The grids in this data release reveal landscape features shaped by coastal, glacial, and tectonic processes that are essential for monitoring the impacts of climate change, determine rates of shoreline migration, and assess the potential for natural hazards. The data therefore contribute to studies of past glacier advance and retreat, mountain building, regional geology, and landscape change driven by glacial rebound and active tectonics. The data also helps in reconstructing the history of past earthquakes, thus improving national seismic hazards assessments.
