Peterson, D.E., and Finn, C.A., 2020, Bouguer gravity and magnetic susceptibility measurements at Iliamna Volcano, Alaska 2019: U.S. Geological Survey data release, https://doi.org/10.5066/P90Q3ZQ8.

Summary

Gravity data were collected in August of 2019 at 21 sites on and around Iliamna Volcano and Anchorage, Alaska. Measurements were taken with a Lacoste & Romberg G-161 meter and reduced to obtain the complete Bouguer anomaly. A total of 39 magnetic susceptibility measurements were taken at 13 locations using a ZH Instruments SM30 susceptibility meter. This data release includes susceptibility measurements, processed gravity data, shapefiles with field locations, and site photos.
