An open lava channel was feeding a flow that had merged with another, and both were advancing along the southern edge of previous flows, the Hawaiian Volcano Observatory said Friday.

Scientists at the U.S. Geological Survey's observatory were monitoring the ongoing dramatic change in the 24-year eruption of Kilauea.

On July 21, a new outbreak of lava occurred to the east of Puu Oo vent. It was the first time lava erupted in the area outside Hawaii Volcanoes National Park since 1992.

The new eruption site is situated on lands adjacent to the park in the Kahaualea Natural Area Reserve, which is administered by the state Department of Land and Natural Resources.

Access to the remote area, which is not accessible by car or by hiking, is closed to the public.
