Channel crusting over at the base Halema'uma'u's west vent

Detailed Description

The west vent in Halema‘uma‘u crater continues to erupt at Kīlauea’s summit. These telephoto images from December 29 (left) and December 30 (right) compare the lava lake surface below the west vent. The west vent is supplying lava to the lake through a crusted over channel, which was starting to form by December 30. USGS photos by H. Dietterich.
