Kīlauea Volcano —

Comparison of photographs taken on June 13 and 26 from near Keanakāko'i Crater overlook in Hawai'i Volcanoes National Park shows a subsidence scarp that formed as the Kīlauea Crater floor subsided. Scientists estimate the dramatic dropping of the crater floor in this area occurred sometime between June 23 and 26. The view is to the west. Halema‘uma‘u crater is in upper

Kīlauea Summit UAS footage shows an ever growing Halema‘uma‘u

A UAS mission on June 24, 2018, filmed details of the dramatic changes occurring within Halema‘uma‘u crater at Kīlauea's summit since explosive eruptions of ash and gas and ongoing wall collapse began in mid-May. Clearly visible are the steep crater walls that continue to slump inward and downward with ongoing subsidence at Kīlauea's summit. The deepest part of Halema‘uma‘

Kīlauea Volcano — Documenting Fissure 8 Activity

USGS Hawaiian Volcano Observatory geology field crews maintain watch over the eruptive activity in the lower East Rift Zone and at Kīlauea's summit. Here, a geologist documents the behavior of lava as it exits the Fissure 8 cone. Lava enters the upper channel traveling as fast as 30 km/hour (18 mi/hour).

Kīlauea Volcano — Ocean Entry

Lava is entering the sea on the southern side of the entry area primarily through the open channel, but also along a 1 km (0.6 mi) wide area. The entry areas are marked by billowing laze plumes. The interaction of lava with the ocean creates "laze", a corrosive seawater

Kīlauea Volcano — Lava Flows from Fissure 8

View to the southwest, looking "up" the lava channel. Lava flows from Fissure 8 (not pictured) through the open channel about 13 km (8 mi) to the ocean. Lava remains incandescent (glowing orange) along the entire length of the channel with sections of cooled lava (black) on the surface. The dark areas in the lower portion of the image are parts of the early lava flow from

Did aerial bombing stop the 1935 Mauna Loa lava flow?...
November 30, 2017

A widely-held belief is that Thomas Jaggar, founder of the Hawaiian Volcano Observatory, was able to stop a Mauna Loa lava flow in 1935. But is it true?

CT scans and photographs of coral collected from reef near polluted groundwater seeps. One set shows more erosion than the other

November 23, 2017

If you follow Kīlauea Volcano's ongoing East Rift Zone eruption, you are likely aware that when lava enters the ocean, it often forms new land. But what is this new land called?

October 26, 2017

Using detailed geologic mapping and modeling of how a fluid (in this case, lava) responds to surface topography, USGS-HVO constructed nine maps depicting 18 inundation zones on Mauna Loa. Each zone identifies a segment of the volcano that could erupt lava and send flows downslope.
