This view shows Kīlauea's summit lava from the south, with the east slope of Mauna Loa in the background and Mauna Kea in the distance. The Hawaiian Volcano Observatory and the Hawai‘i National Park Service Jaggar Museum buildings are visible on the rim of Kīlauea's summit caldera, behind Halema‘uma‘u. The dark lava flow on the floor of Halema‘uma‘u was mostly erupted during April-May 2015.
