Earthquakes are not common in Vermont, but they do happen here.  Since 1997 the Geological Survey has partnered with DEMHS, UVM, FEMA, Norwich University, NESEC and others to conduct studies and outreach which serve to inform Vermonters and assist with emergency preparedness.  Completed projects include site class, amplification and liquefaction hazard maps, seismic vulnerability of critical facilities, HAZUS damage assessments, and outreach to local government, private engineering firms and the general public.

Geothermal Energy

Geothermal Log

The Geological Survey focused on collecting water well temperature data as an indicator of temperature gradients, radionuclide chemistry as a potential natural augmentation to heat production, thermal conductivity measurements which impact heat flow, and structural data particularly rock anisotropy and fracture data. Thermal conductivity and geochemical data for 40 rock samples plus 17 water well temperature records were uploaded to the National Geothermal Data System for easy access.

Geology Publications and GIS On-line

As a service, we also host publications of the Vermont Geological Society and many USGS maps which were compiled for the 2011 Bedrock Geologic Map of Vermont.  The full list of publications is in the left navigation bar.

Mapping Program

The mapping program produces bedrock and surficial geologic maps by town, quadrangle and watershed. It is funded through STATEMAP, an annual competitive grant process through the National Cooperative Geologic Mapping Program of the U.S.Geological Survey. The State Mapping Advisory Committee, comprised of legislators, consultants, geologists, and mineral industry personnel, meets with the State Geologist to review the map program and make recommendations concerning the goals of this project.
