Aug. 6 explosive event at Kīlauea's summit

On August 6, a rockfall from the steep walls of Overlook crater, which contains Kīlauea Volcano's summit lava lake, triggered an explosive event that deposited spatter (molten lava) and solid rock fragments on the rim of Halema‘uma‘u Crater. That event was just the latest in a series of explosions that began in 2008. In this photo, the surface of the lava lake has a silvery sheen, and two areas of vigorous spattering appear orange in color. USGS photo.
