Kīlauea Volcano — Fissure 8 Cone Building

The Fissure 8 viewed from the north at 7:50 AM. The cone is roughly 50 m (165 ft) high at is peak, and a plume of sulfur dioxide and other volcanic gases rises as an orange tinge from the erupting lava fountains (hidden within the cone). Lava is still flowing out of the ventunabated as a full channel. To the left of the cone, a standing wave of lava can be seen in the

Kīlauea LERZ lava flows and fissures, June 13, 10:00 a.m.

Map as of 10:00 a.m. HST, June 13, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.
