Kīlauea Volcano — Halema‘uma‘u Crater

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

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.

Kīlauea summit activity

A series of wide-angle webcam images, captured by a camera in HVO's observation tower (https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html) between June 1 and June 10, 2018, show ongoing subsidence around Halema‘uma‘u at the summit of Kīlauea in this animated GIF.

Kīlauea Volcano — Overflight of Ocean Entry

The interaction of molten lava flowing into cool seawater causes pulsating "littoral explosions" that throw spatter (fragments of molten lava) and pieces of solidified glassy lava (black sand, Pele's hair, limu o Pele) high into the air. In this aerial view of the Kapoho ocean entry, these dark-colored lava particles are blasted skyward through billowing white clouds of

Kīlauea Volcano — Cracked Road at Summit

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 Volcano — Fissure 8 from a Distance

Distant view of Kīlauea Volcano's fissure 8 lava channel from HVO's early morning overflight on June 10, looking to the southeast. Bryson's cinder quarry is the brown patch just to the north of the channel.

Kīlauea LERZ eruption

Fissure 8 continues to erupt vigorously, with lava streaming through a channel that reaches the ocean at Kapoho Bay. The width of the active part of the lava channel varies along its length, but ranges from about 100 to 300 meters (yards) wide. A clear view of the cinder-and-spatter cone that's building around the vent from ongoing lava fountains can be seen here.

Kīlauea Volcano — Fissure 8 Lava Channel

A closer view of the fissure 8 lava channel with the cinderquarry more clearly visible in the foreground (bottom of photo). During this morning's overflight, HVO geologists observed no new breakouts of lava near this quarry.

In 1888, Tavernier went one step further and created what we would now call a virtual reality depiction of Kīlauea volcano—the "Panorama of Kīlauea," an 11-foot tall canvas arranged in a circle with a 90-foot circumference.
