Kīlauea Volcano — Documenting Fissure 8 Activity

USGS Hawaiian Volcano Observatory geology field crews maintain watch over the eruptive activity in the lower East Rift Zone and at Kīlauea's summit. Here, a geologist documents the behavior of lava as it exits the Fissure 8 cone. Lava enters the upper channel traveling as fast as 30 km/hour (18 mi/hour).

Kīlauea summit subsides and produces frequent earthquakes

On June 23, 2018 at 4:32 p.m. HST after approximately 17 hours of elevated seismicity, a collapse explosion occurred at the summit if Kīlauea. The energy released by the event was equivalent to a magnitude 5.3 earthquake. During the intense shaking, rockfalls cascaded down the northern margin of the caldera wall just below Uēkahuna Bluff sending rock dust into the air.

Kīlauea Volcano — Ocean Entry

Lava is entering the sea on the southern side of the entry area primarily through the open channel, but also along a 1 km (0.6 mi) wide area. The entry areas are marked by billowing laze plumes. The interaction of lava with the ocean creates "laze", a corrosive seawater

View to the southwest, looking "up" the lava channel. Lava flows from Fissure 8 (not pictured) through the open channel about 13 km (8 mi) to the ocean. Lava remains incandescent (glowing orange) along the entire length of the channel with sections of cooled lava (black) on the surface. The dark areas in the lower portion of the image are parts of the early lava flow from

The caldera was a dynamic place during the 300-plus years just before written history began at Kīlauea (in 1823), and the newly defined subdivisions of the Keanakāko‘i Tephra help us understand this energetic and dangerous time better than did the previous terminology.
