Lava flowing into Halema‘uma‘u from multiple channels 12/28/2020

Lava flowing from the western fissure vent feeds multiple channels. This video was taken by Hawaiian Volcano Observatory's geology field team on December 28, 2020, from 2:30 to 5:30 p.m. The team is located at an observation point on the rim of Halema‘uma‘u crater, and is using a telephoto lens to document fissure behavior. During the three-hour period, the field team

Using a laser ranger finder to measure Kīlauea summit eruption

HVO field crews have been using a laser range finder to measure the vertical distance between points of known elevation and features of the ongoing eruption, such as the lava lake surface level and the erupting vents. This morning, the eruption continues at the west vent in Halema‘uma‘u, and streams of lava about 40 m (131 ft) pour from the vent to the lava lake surface.

The western vent in Halema‘uma‘u crater wall at Kīlauea summit remains active but field crews monitoring the eruption this morning (December 27) noted that its vigor is somewhat reduced from yesterday. Where three open channels were observed yesterday, there are only two today. Of the three locations that have been erupting at the west fissure vent, the eastern one has

HVO field crews were unable to observe early morning eruption activity in Halema‘uma‘u crater at Kīlauea's summit due to high winds. Upon return to the eruption site this morning, HVO field crews noted the reduced vigor at the western vent. The northern/eastern vent remains inactive. At approximately 7:30 a.m. HST today (Dec. 27), HVO field crews measured the lava lake as

The west vent remained active overnight, with strombolian-like bursts and lava cascades. Lava cascading from the vent plunges into the lava lake in multiple places, causing local upwelling. As the cascades enter the lava lake, they cause the

The 2018 lower East Rift Zone (LERZ) eruption of Kīlauea brought an end to the 35+ year eruption at Pu‘u ‘Ō‘ō. With the draining of the summit and the collapse of Pu‘u ‘Ō‘ō, Puna residents were concerned that the eruption in the LERZ could be long-lived.

One of the most frequent questions asked of USGS Hawaiian Volcano Observatory (HVO) scientists the last several months has been, “Is the lower East Rift eruption over?” But the same question could – and should – be asked of the Pu‘u ‘Ō‘ō eruption.
