Tsang, C.S., Zoeller, M.H., Moore, R.B., and Trusdell, F.A., 2020, Digital database of the geologic map of Alamagan Volcano, northern Mariana Islands: U.S. Geological Survey data release, https://doi.org/10.5066/P9KUIBML.
Summary
Alamagan Volcano is a Quaternary stratovolcano along the Mariana Arc, an active subduction zone in the western Pacific Ocean. Although primarily submerged, its peak reaches above sea level, with subaerially-exposed volcanic deposits dating back through the Holocene to the late Pleistocene. These feature data represent such deposits and other geologic features of Alamagan Volcano, describing its interpreted eruptive history.
