Summit lava lake level continues dropping

Detailed Description

The summit lava lake level continued to drop through Saturday July 29 as the summit deflated. Rockfalls from the Overlook crater walls have been frequent over the past two days, due to the lowering lava level, and these collapses trigger spattering in the lake. The spattering in this telephoto image created a local sink in the lake, causing surrounding crust to plunge towards the spattering.
