West vent fountaining, Kīlauea summit—October 25, 2021

Detailed Description

Lava continues to erupt from the west vent in Halema‘uma‘u, at the summit of Kīlauea. Low lava fountains of only a few meters (yards) tall were common on October 25, with higher bursts sometimes reaching up to 12 meters (39 ft). The cone was measured at 25 meters (82 ft) above the active lava lake surface. Lava ponded inside the cone flows down the spillway—which is about 7 meters (23 ft) long—supplying lava into the lake below. USGS Photo taken from the southern crater rim by K. Lynn.
