Photo and Video Chronology – Kīlauea – May 25, 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 229 m (751 ft) deep this morning, May 25. Summit gas emissions and seismic activity remain slightly 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 the evening of May 24, no active surface lava was observed within Halema‘uma‘u crater, at the summit of Kīlauea Volcano. Small spots of incandescent lava were visible beneath cracks in the lake surface crust (center) and at the west vent (left). This photo was taken from the western rim of Halema‘uma‘u, in an area of Hawai‘i Volcanoes National Park that remains closed to the public due to safety reasons. USGS photo taken by B. Carr.

A zoomed-in view of the western lava lake in Halema‘uma‘u, at Kīlauea summit, where two locations of faint incandescence are visible beneath the surface crust (upper right). Eruptive activity has decreased significantly in the past few weeks and the once active lava surface has cooled and crusted over. USGS photo taken by B. Carr at dusk on May 24, 2021.
