North fountain continues to drop and is less than 300 feet (90 meters) high. The UWD tiltmeter recorded about 15 microradians of deflation, about equal to the amount of inflation. View All Messages.

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.
