Photo and Video Chronology – Kīlauea – March 18, 2021

Release Date:

Kīlauea's summit eruption continues on the Island of Hawai‘i; the west vent in Halema‘uma‘u erupts lava into the lava lake. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear and PPE—monitor the current 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.

Active lava lake at the summit of Kīlauea Volcano

On St. Patrick's Day, March 17, 2021, a rainbow was observed adjacent to the active lava lake at the summit of Kīlauea Volcano. This photo was taken around 11:00 a.m. HST from the south rim of Halema‘uma‘u crater. In the nearly three months since the eruption started on December 20, 2020, the active surface of the lava lake has risen to approximately 222 m (728 ft). USGS Photo by J. Chang.
