Summary

In 2022, the U.S. Geological Survey (USGS) in cooperation with the New Hampshire Department of Transportation (NHDOT) made 107 horizontal-to-vertical spectral ratio (HVSR) passive seismic geophysical measurements at four transportation infrastructure sites in New Hampshire to determine the benefits of HVSR as an enhancement to traditional geotechnical site characterizations performed by NHDOT. Typically, data are obtained from the subsurface during borings to characterize geotechnical properties but often borings are spaced hundreds of feet apart. Geotechnical site characterization guided by geophysical surveys (such as the HVSR method) between borings will help provide a more thorough characterization. By combining analysis of geophysical [...]

Purpose

This data release makes HVSR data available to evaluate the rapid application of geophysical reconnaissance methods in the vicinity of geotechnical borings at NHDOT sites. The ability to identify anomalies representing bedrock in areas not characterized by geotechnical borings will be tested.
