The largest spatter bombs traveled the farthest, perhaps aided by momentum, landing on the trail between the Halema‘uma‘u parking area and overlook. Upon landing, these bombs splatted to form complexly shaped bomb fragments connected by thick strands and masses of Pele's hair.

Only a relatively small amount of spatter reached the rim of Halema‘uma‘u, compared to the thick, continuous layer of spatter seen here on the intermediate ledge midway between the lava lake and the Halema‘uma‘u Crater rim.

This VIDEO CLIP shows a cloud of ash and spatter being thrown from the summit lava lake during today's explosive event. The images were captured by an HVO webcam located on the rim of Halema‘uma‘u Crater, just above the rockfall area. Spatter falling onto the crater rim is a reminder of the hazards that exist in this area, which has been closed since 2008.

A clear evening provided good views of the lava lake within Halema‘uma‘u Crater at the summit of Kīlauea Volcano. Spattering was active along the south margin (left side) of the lava lake, with the gas plume drifting to the southwest (upper left).

This close-up view of the lava lake surface on the south side of the lake shows a typical spreading zone. In this image, the crustal plates on both sides of the incandescent line are migrating to the south (toward the lower left corner of the photo), but the crust on the left side is moving more rapidly to the south than the crust on the right.

HVO geologists hiked across the 61g flow field to investigate this breakout at the base of the pali on Kīlauea Volcano's south flank. Toes of active pāhoehoe lava were slowly advancing on top of older ‘A‘ā and pāhoehoe flows erupted earlier this year.

A past assumption about pumice deposits on Kīlauea Volcano has recently been proven wrong. In this photo, the eastern pumice (EP) can be seen above the golden pumice (GP), with stream deposits between the two. Photo courtesy of Sebastien Biasse, University of Hawai‘i at Mānoa.

A breakout started from the episode 61g vent on the east flank of Pu‘u ‘Ō‘ō yesterday morning (Monday, November 21) at around 08:40 AM. The breakout sent lava flows south and northeast, and these flows were still active as of Tuesday afternoon (November 22).

Volcanologists collaborate on how to best communicate volcanic hazard and risk via long-term assessments at the third Volcano Observatory Best Practices workshop in Vancouver, Washington from November 15th to 18th, 2016.

The level of the lava lake at the summit of Kīlauea has been high recently, providing good views of spattering from the Jaggar Museum visitor overlook in Hawai‘i Volcanoes National Park. This photo shows activity as viewed from the rim of Halema‘uma‘u Crater (closed to the public since 2008 due to volcanic hazards). Spattering is common, and on Sunday (Nov.

Foundering of the lava lake crust is common near the lake's margins. The triangular-shaped slab of crust (left of photo's center) was sinking back into the lake as more fluid lava upwelled around it.
