An image from a Halema‘uma‘u time-lapse camera taken on December 5 at 4:41 am, just after the collapse. The portion of the rim that fell into the Halema‘uma‘u lava lake triggered intense spattering on the lake margin where the material impacted the lake. The collapse also agitated the entire surface of the lava lake, breaking up the crustal plates into many small ones. Photo taken Tuesday, December 5, 2017 courtesy of U.S. Geological Survey
