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 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 Volcano — Overflows from Fissure 8

Overflows of the upper fissure 8 lava channel this morning sent small flows of lava down the levee walls. These overflows did not extend far from the channel, so they posed no immediate threat to nearby areas. Channel overflows, like the ones shown here, add layers of lava to the channel levees, increasing their height and thickness.

Kīlauea Volcano — Topography of Halema`uma`u

A photogrammetry survey of Kīlauea's summit by the U.S. Department of Interior Unmanned Aircraft Systems' (UAS) Kīlauea response team show the topography of Halema‘uma‘u as of June 8. Cracks through the former overlook parking lot (bottom of image) wrap around the east margin of Halema‘uma‘u; the once-popular overlook viewing area (closed since 2008 due to volcanic hazards

Everyone extrapolates facts and makes assumptions based on those facts. Sometimes, such an assumption is repeated so often that it takes on the aura of a "fact" itself. This is the story of how one such assumption about Kīlauea's recent past was proven wrong—and only in the past couple of months!
