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.

Pro-SRZ™ 2.0 Guards are more effective at dispersing force when compared to competitors’ guards because of EvoShield’s proprietary Gel-to-Shell® Technology.*

2025年3月6日 · During eruptions, USGS Hawaiian Volcano Observatory (HVO) scientists employ a variety of techniques to collect and disseminate map data depicting key eruptive features, especially lava flows. Mauna Loa's recognized eruptive pattern is a summit eruption followed—within hours, days, or months—by a flank eruption.
