HVO scientists collect detailed data to assess hazards and understand how the eruption is evolving 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.

View of the active lava lake in the eastern side of Halema‘uma‘u crater, at the summit of Kīlauea. A perched levee consisting of stacked crustal plates a few meters (yards) tall surrounds the lake. A fountain (orange) is present on the southwest side of the lake. At the time the photo was taken, a flow had breached the levee on the south (right) side. USGS photo by J.M. Chang.
