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.

Kīlauea summit activity

Another explosion occurred at Halema‘uma‘u at 12:51 a.m. HST today, releasing energy equivalent to a magnitude-5.3 earthquake. Following the explosion, summit activity consisted mostly of passive degassing at Halema‘uma‘u, similar to what is shown in this image taken mid-morning. Seismicity at the summit decreased after the explosion, but has been increasing throughout

A photogrammetry survey of Kīlauea's summit by the U.S. Department of Interior Unmanned Aircraft Systems' (UAS) Kīlauea response team show changes that have occurred at 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 and extend to the north. New faulting and slumping apparent on west

Kīlauea Volcano — Lava Delta at Kapoho Bay

A closer aerial view of the lava delta forming at the Kapoho Bay ocean entry, where fissure 8 lava continued enter the ocean as of this morning. Laze (lava haze), an acidic white plume laced with tiny particles of volcanic glass, is produced by the ocean entry and creates an ongoing hazard that should be avoided.

Kīlauea Volcano — Kapoho Bay Ocean Entry Plume

The fissure 8 lava flow reaches the ocean at Kapoho Bay, where a lava delta has formed and continues to grow as lava enters the sea. The largest white laze

Kīlauea Volcano — GPS Measurements at Summit

USGS-HVO geophysicists installed additional continuous GPS stations around Halema‘uma‘u this morning. These stations will allow scientists to better monitor and measure the ongoing subsidence of Halema‘uma‘u and the adjacent

Kīlauea Volcano — Fissure 8 Lava Channel

Fissure 8 and lava channel in the lower East Rift Zone of Kīlauea Volcano during this afternoon's overflight, with no apparent slowing in the eruption rate. The lava channel remained incandescent all the way around Kapoho Crater before entering the ocean.

Kīlauea Volcano — Kapoho Ocean Entry

An aerial view of the Kapoho ocean entry, as of 6:30 a.m. HST today, shows the extent of the lava delta, now about 200 acres in size, that has formed over the past six days (lava first entered the ocean on the night of June 3). Across the front of the delta, plumes of laze—created by molten lava interacting with seawater—appeared diminished this morning, but was probably

Kīlauea Volcano — Halema`uma`u Cracking and Slumping

Cracking and slumping of the Halema‘uma‘u crater walls are clearly evident in this aerial view captured during HVO's overflight of Kīlauea's summit this morning. Steam plumes have been rising from within the crater, as well as from cracks adjacent to the crater.

Amber waves of … Pele's hair?...
October 20, 2016

The lava lake within Halema‘uma‘u Crater at the summit of Kīlauea Volcano is creating a scene remindful of a messy barbershop floor, except that it's acres and acres wide rather than a few square feet. The ground downwind of the crater is strewn with Pele's hair, and it is almost impossible to avoid stepping on it.
