Lava fountain peak height, Kīlauea Iki eruption, Kīlauea

Close view of the fountain and incandescent lava fragments falling back to the ground. During the fountaining episodes, scientists described seeing a few incandescent pieces of pumice more than 100 m (330 ft) above the lava fountain, and cooler pieces rising even higher in the hot draft above the fountain. Variations in the wind created a constantly changing pattern in the "pumice plume" that was mesmerizing to watch. Often, glowing clouds of pumice swirled directly overhead, only to be blown far away into the forest before falling to the ground.
