Kauahikaua began his career with the
USGS in 1976, originally working out of
Denver, but then moved to
Hawaii after a year. In 1998, he participated in an archaeology excavation in
Hawaiʻi Volcanoes National Park with the
U.S. Department of the Interior. This work was featured in part of a 2003 report. As well as his academic papers, his research was cited or otherwise used in multiple
U.S. Government reports. Kauahikaua was awarded funds from the
National Science Foundation for research in collaboration with the
University of Oregon for the
fiscal years. Kauahikaua served as scientist-in-charge of the Observatory from 2004 to 2015, preceding
Tina Neal and following
Donald A. Swanson. During this time, he coordinated responses to multiple notable geologic events, including the
Mauna Loa unrest of , the
Kīholo Bay earthquake, as well as other eruptions at
Kīlauea and elsewhere. He stepped aside after over ten years to make room for personal research. He continued to work for the Observatory through the
2018 lower Puna eruption, and continued to work there as a research geophysicist. In May 2015, he won a DOI Meritorious Service Award from the
U.S. Department of the Interior in recognition of his scientific work for the Geological Survey. In 2019, he appeared as a panelist at a workshop hosted by
University of Colorado Boulder, in which he talked about his experiences as a Hawaiian volcanologist and gave perspective to the 2018 eruption of
Kīlauea. Kauahikaua was often consulted by the news media as a volcanology expert, especially during the
2022 eruption of Mauna Loa.
Writing Kauahikaua was the author of
Volcano: Creation in Motion, a book about
Pele, the Hawaiian deity of volcanoes. ==References==
