Lava spatter and splashing build cones at Fissure 22, in Kīlauea Volcano's lower East Rift Zone. This video from May 21, 2018, ~8:50 AM, HST, shows how splashing and spattering lava builds cones around fissure sites. The height of the cone at the lower fountain (to the left) is about 14 m (~45 ft). The height of the large lava fountain in the middle is about 46 m (~150 ft).
