Photo and Video Chronology – Kīlauea – March 29, 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.

The lava lake remains active in Halema‘uma‘u Crater, at the summit of Kīlauea. The surface area of the active lava lake has slowly decreased over the past several months, with the active surface lava now limited to a portion of the west side of lake. The lake remains perched several meters (yards) above its surroundings, bound by a steep levee on most sides. USGS photo by M. Patrick.
