An HVO geologist captures video of the episode 14 fountaining at the summit of Kīlauea. The videos are time-synchronized to better compare to geophysical data, for later study. USGS photo taken by M. Patrick on March 20, 2025.

HVO monitors earthquakes and the active volcanoes in Hawaii, assesses their hazards, issues warnings, and advances scientific understanding to reduce the impacts of volcanic eruptions. Communicating the results of our work to the public, emergency managers, and the scientific community is an important aspect of the HVO mission.
