VIDEO: Rockfall Triggers an Explosive Event in Summit Lava Lake

Video clip captured by HVO webcam on Monday, November 28, 2016 at 11:59 a.m. shows a rockfall from the south wall of Halemaʻumaʻu Crater triggering a small explosive event in the summit lava lake.

The explosion threw spatter (fragments of molten lava) onto the rim of the crater, mostly to the west of the former visitor overlook.

This area has been closed to the public since 2008 due to ongoing volcanic hazards, including explosive events like the one that happened today.
