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.

A USGS-HVO scientist collects Pele's hair from the parking area south of Halema‘uma‘u Crater, which has been closed since early 2008 due to ongoing volcano hazards associated with the summit lava lake.

A close-up of Pele's hair from Kīlauea Volcano's summit lava lake. X-ray diffraction analyses of the Pele's hair (basaltic glass) collected today will provide information on the mineralogy of Kīlauea lava, which, in turn, can shed light whether the magma supply to the volcano is constant or is changing.

This video shows activity in the summit lava lake in Halema‘uma‘u Crater. Spattering like this is common in the lake, and this video shows the view from the rim of Halema‘uma‘u (closed to the public due to volcanic hazards). This spattering has recently been visible from the Jaggar Overlook inside Hawai‘i Volcanoes National Park (open to the public).

This photo shows the Hawaiian Volcano Observatory and the Hawai‘i Volcanoes National Park Service Jaggar Museum buildings on the summit of Kīlauea Volcano, overlooking the summit caldera. Mauna Loa volcano looms in the background.

This view shows Kīlauea's summit lava from the south, with the east slope of Mauna Loa in the background and Mauna Kea in the distance. The Hawaiian Volcano Observatory and the Hawai‘i National Park Service Jaggar Museum buildings are visible on the rim of Kīlauea's summit caldera, behind Halema‘uma‘u.
