Photo and Video Chronology – Kīlauea – April 27, 2021

Release Date:

Kīlauea's summit eruption continues on the Island of Hawai‘i; Halema‘uma‘u west vent erupts lava into the lava lake, which was 227 m (744 ft) deep this morning, April 27. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear—monitor the eruption from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.

HVO scientists collect detailed data to assess hazards and understand how the eruption is evolving at Kīlauea's summit, all of which are shared with the National Park Service and emergency managers. Access to this hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park.

On Monday, April 26, 2021, lava continued to flow from the western vent into the active lava lake in Halema‘uma‘u Crater

On Monday, April 26, 2021, lava continued to flow from the western vent (bottom left) into the active lava lake (center) in Halema‘uma‘u Crater at the summit of Kīlauea Volcano. The active lava lake surface continues to shrink as areas on the north (upper left) and south (center right) sides cool and solidify. This photograph was taken at 1:03 p.m. HST from the west rim of Halema‘uma‘u, an area within Hawai‘i Volcanoes National Park that remains closed to the public due to safety reasons.

A close-up view of the west vent spatter cones (bottom left) and inlet where lava is entering the lava lake (center right) in Halema‘uma‘u Crater at the summit of Kīlauea Volcano. A piece of crust, that solidified near the inlet, broke off and was being transported away from the inlet.
