December 27, 2020—Kīlauea summit eruption reference map

Kīlauea summit eruption reference map showing the location of ongoing lake activity

Detailed Description

The ongoing eruption at Kīlauea Volcano's summit, within Halema‘uma‘u crater, has formed a lava lake that is now being fed by one fissure at its western end. The lake reached its greatest height and extent on December 25, but draining into the now-inactive north vent lowered the lava level by several meters (yards). This left a berm of lava that now bounds the slightly smaller lake, within which there are several islands, the two largest of which are marked in yellow. A dashed blue line indicates the extent of the water lake that existed in the crater until December 20, and a dashed black line indicates the extent of the 2008–2018 lava lake in Halema‘uma‘u.
