Hawaii Volcano Observatory

The Hawaii Volcano Observatory (HVO) is a research facility that monitors volcanic activity in Hawaii, primarily focused on Kilauea and Mauna Loa volcanoes. Established in 1912, HVO scientists study eruptions, gas emissions, and ground deformation to provide critical information about volcanic hazards. Their work helps to keep residents and visitors safe by predicting eruptions and understanding volcanic behavior. The observatory also conducts research to advance our knowledge of volcanology and shares findings with the public and policymakers to promote awareness and preparedness in volcanic areas.
