The Alaska Division of Geological and Geophysical Surveys (DGGS) assesses potential geologic hazards to infrastructure, including buildings, roads, and infrastructure. DGGS facilitates local community-based monitoring efforts by collecting and providing access to reliable data.
The DGGS Coastal Hazards Program is dedicated to studying Alaska’s coastline and how it will respond to hazardous events and long-term changes, including flooding and erosion. The program supports coastal planning by closing information gaps, converting data to usable formats, and educating the public about Alaska’s changing shoreline.
The Alaska Shoreline Change Tool displays historic and predicted shoreline position throughout Alaska.
