Geology and Hazards

Great Brook LandslideThe Geological Survey provides reliable, science-based information about frequency, magnitude, extent, and consequences of physical hazards, and when possible, hazard avoidance strategies.  To address potential risks, the Division conducts local and regional hazard assessments such as the Landslide Hazard Mapping project.  By identifying regions sensitive to physical hazards and utilizing a scientific assessment to characterize the risks, the Division provides a tool to protect Vermonters in vulnerable areas.  Information developed for landslides, earthquakes, flood and drought contributes to mitigation and preparedness for these low frequency, high impact events.  

As an early geologic responder to landslides, qualitative assessments are made of the likelihood of continued slope failure and risk to Vermonters.  The Geological Survey works with Regional Planning Commissions, VEMHS, and towns to implement the landslide hazard mapping protocol and planning.  Report a Landslide is a new  online feature in which the public can add to our landslide inventory. We also use  LiDAR data (available through VCGI) to identify possible areas of concern and map active and inactive landslides.

Geologic hazards such as earthquakes and floods  are part of the Geologic Hazards Program. Since 1997 the Geological Survey has partnered with VEMHS, UVM, FEMA, Norwich University, NESEC and others to conduct studies and outreach which serve to inform Vermonters and assist with emergency preparedness.  Emergency preparedness, particularly of critical facilities, is informed through these studies. Mapping of surficial materials  identifies areas of unconsolidated materials which may amplify shaking during a seismic event.  

Regional groundwater studies  provide data for drought resiliency and response. Geochemical  and mineral-related hazards  such as arsenic and radionuclides are addressed in the Geology and Health  Program. FEMA has a number of mitigation ideas and strategies for communities to implement.
