This 3-dimensional computer model shows the structure of the fissure
8 cone on Kīlauea Volcano's lower East Rift Zone. The model was created from thermal
images acquired during a helicopter overflight on August 15, 2018. The cone is currently about 30 m (100 ft) tall with a broad base. The bright white area within the cone is a small pond of lava
, now largely crusted over, which is currently at a level near that of the pre-eruption ground surface. The open side of the cone is the spillway where lava, during the height of the eruption, flowed from the vent
into the channel that transported molten lava about 13 km (8 mi) to the sea.
