December 31, 2020—Kīlauea summit eruption

Detailed Description

Kīlauea's summit lava lake in Halemaʻumaʻu is continually re-surfacing. HVO geologists monitoring the activity in the field have observed crustal foundering, in which pieces of solidified lava crust on the surface of the lava lake break and sink back into the liquid portion. USGS photo by M.
