• Project ID:

  1660

• Nickname/Abbreviation:

  ALHP

• Parent Project:

  Geologic Hazards Section programs and projects

• Status:

  Ongoing

• Description:

  This 5-year project begins USGS support for DGGS landslide hazard data collection and assessment activities within the Alaska Landslide Hazards Program. In this cooperative agreement, we will identify, assess, and monitor unstable slopes in Prince William Sound (PWS) and begin developing a database to hold statewide information on Alaska landslides. The project will increase our understanding of landslide hazards across the state and, in particular, increase the preparedness and resilience of Southcentral and Southeast Alaska coastal communities and deliver critical information for stakeholder decision making.
