Kīlauea summit eruption in Halemaʻumaʻu crater - October 2, 2021

Low lava fountains near the southeast edge of the main island in the Halema‘uma‘u lava lake, during the ongoing Kīlauea summit eruption. One of the small (less than 5 meters or 16 feet) fountains has built a cone on the edge of the island. Occasional spatter is ejected from the vent at the top of the cone while the main fountain is directed laterally onto the lava lake surface from within the grotto that it formed near the base of the island.
