Kīlauea's summit is no longer erupting; lava supply to the Halemaʻumaʻu lava lake has ceased and sulfur dioxide emissions have decreased to near pre-eruption background levels. HVO field crews—equipped with specialized safety gear—monitor for new changes from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.
HVO scientists collect detailed data to assess hazards and understand evolving processes at Kīlauea's summit, all of which are shared with the National Park Service and emergency managers. Access to this hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park.
