Another small explosive event at Kīlauea's summit lava lake

On January 4, a rockfall within the Overlook vent at the summit of Kīlauea generated another small explosive event at 3:18 a.m., HST. In this image, captured by a USGS Hawaiian Volcano Observatory webcam, the dusty gas plume can be seen rising from the vent after rocks impacted the lava lake. Incandescence from molten lava exposed by the disrupted lava lake surface lit up the vent wall and the night sky above Halema‘uma‘u Crater.
