Kīlauea Volcano — Braided Lava Channels

Fissure 8 (fountain visible in distance) feeds lava into an active braided channel that flows about 8 miles (north, then east) to the ocean entry in Kapoho Bay. USGS image taken June 12, 2018, around 6:50 a.m. HST.

Kīlauea Volcano — Halema`uma`u Crater Cracks

A closer view of the cracks cutting across the parking lot for the former Halema‘uma‘u visitor overlook (closed since 2008, when an active vent opened within the crater). Additional photos—ground views—of the parking lot cracks were posted on June 7 and 11.

Kīlauea summit

Events at the summit of Kīlauea over the past few weeks have dramatically reshaped Halema‘uma‘u, shown here in this aerial view, which looks west across the crater. The obvious flat surface (photo center) is the former Halema‘uma‘u crater floor, which has subsided at least 100 m (about 300 ft) during the past couple weeks. Ground cracks circumferential to the crater rim

This 'warped-curb' crack, the largest in the parking area for the former Halema‘uma‘u overlook (closed since 2008), is one of many that have sliced the parking area into slices. Ballistics (blocks of solid rock) strewn across the area are visible in the foreground. Loose, dislodged

Kīlauea LERZ lava flows and fissures, June 11, 3:00 p.m.

Map as of 3:00 p.m. HST, June 11, 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.

The ash deposits on the southeastern part of the Island of Hawai‘i have fortuitously presented an agricultural opportunity in an otherwise rocky and hilly landscape. An underappreciated fact is that the explosive nature of our volcanoes provided this opportunity.
