Coastal Hazards

Alaska's Environmentally Threatened Communities StoryMap Access this StoryMap here

144 communities in Alaska are threatened by flooding, erosion, and permafrost degradation. DGGS tracks data and tools to support decision-making by agencies, Tribal organizations, communities, and partners for the collective "all hands on deck" response to environmental threats.

About the Program

The DGGS Coastal Hazards Program is engaged in ongoing investigations that will expand our understanding of how the coastline has evolved and how it will respond to hazardous events and long-term changes. This program is dedicated to fostering scientific partnerships that will improve the quality and quantity of the critical baseline data that are necessary to fuel informed decision-making throughout the state.

The program conducts field investigations at Alaska's coastal communities. Below is a video compilation of our work over the past 5 years. Photos and videos are also shown from our partners at the University of Alaska Fairbanks Arctic Coastal Geoscience Lab.

Erosion Exposure Assessment of Infrastructure in Alaska Coastal Communities

Many communities along Alaska's rivers and coasts are exposed to erosion. DGGS quantified this exposure by forecasting shorelines on existing community infrastructure. Community specific maps and reports are available to aid in erosion decision making.
