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.

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 — 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 — Halema‘uma‘u Cracking

Another aerial view showing prominent cracking around Halema‘uma‘u from the ongoing subsidence at Kīlauea's summit. The steaming cracks in the background have been observed for several days.
