Detailed Description
Quicktime movie of the rockfall and subsequent explosion at 10:20 a.m., HST, on April 28, 2015. Rocks falling into the summit lava lake generated an explosion that threw large fragments of molten lava onto the rim of Halema‘uma‘u Crater, 85 m (280 ft) above the lake. These fragments pose a significant hazard, and are one reason this area remains closed.
