A close-up image of native sulfur crystals that formed within fumaroles at the Sulphur Banks in Hawai‘i Volcanoes National Park. In addition to sulfur species and other gases, volcanoes emit water vapor. Here, some of the vapor has condensed to liquid water and formed droplets visible on the sulfur crystals. USGS photo by P. Nadeau.

Video of the water lake at Kīlauea's summit

This video, taken on September 23, 2020, shows a small area of bubbling or upwelling along the western shoreline of the water lake at the summit of Kīlauea. This feature may result from a submerged fumarole (gas vent) on the crater wall. The extent of this feature is limited and it does not seem to have a significant effect on the overall lake surface activity. No other

Kīlauea's summit water lake comparison - September 23, 2020

HVO geologists made observations of Kīlauea's summit water lake from the east rim of Halema‘uma‘u. This view point is on the large downdropped block that subsided during the 2018 collapse events. From this spot, a view of the entire lake is possible, providing a new perspective on the growth of the lake. The last visit to this spot was on December 18, 2019, when the lake

This view shows Kīlauea's water lake from the east side of the crater. On September 23, 2020, the western portion of the lake (top of image) was the most varied in color, with patches of greenish and brown water. The majority of the lake surface, however, was the typical tan hue. USGS photo by M. Patrick.

Kīlauea Volcano's lower East Rift Zone

lava being blasted upward and outward during a hydrovolcanic explosion
July 20, 2018

Since May 3, 2018, Kīlauea Volcano's lower East Rift Zone eruption has destroyed more than 700 structures, covered more than 32 sq km (12.4 sq mi) of land with black lava, and added about 700 acres of new land to the island. Yet, remarkably, injuries had been few.

Kīlauea Volcano's summit activity produces minor ash

 lava lake within Halema‘uma‘u crater about 3 weeks before magma began to withdraw from beneath the crater.
July 5, 2018

We are currently witnessing extraordinary events at the summit of Kīlauea Volcano. For weeks the summit has subsided both in a continuous fashion and in incremental and jolting drops. As Kīlauea is being reshaped before our eyes, how does the current activity compare to similar collapses at other volcanoes in the world, or even to previous collapses at Kīlauea.

At the summit of Kīlauea Volcano, Halema‘uma‘u has changed dramatically since early May 2018. As the crater walls and inner caldera slump inward, the depth of Halema‘uma‘u has more than tripled and the diameter has more than doubled.
