Aerial Footage Captures Foundering at Kilauea Volcano's Lava Lake

Footage captured by the US Geological Survey (USGS) on December 31 shows crustal foundering at the Kilauea volcano lava lake, a process that turns over the lake crust and renews its surface.

Footage shows foundering at the Halemaʻumaʻu crater. A segment of the cool lava crust sinks into the lava lake, causing a gush of hot, “more fluid” lava to well up around it, the USGS said.

The volcano erupted on December 20. As of December 31, scientists said the lava lake was 181 meters (608 ft) deep. Credit: USGS Volcanoes via Storyful
