Episode 40 produced 7.1 million cubic yards (5.5 million cubic meters) of lava during the high fountain eruption. The average effusion rate was approximately 250 cubic yards per second (190 cubic meters per second) during episode 40. 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.
