Photo and Video Chronology – Kīlauea – October 25, 2021

Release Date:

The ongoing eruption at Kīlauea's summit began at 3:21 p.m. HST on September 29, 2021. Lava activity is currently confined within Halema'uma'u crater. 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.

Color photograph of volcanic vent and lava lake

This photo from the northwest rim of the caldera shows the western vent supplying lava into the lake in Halema‘uma‘u crater, at the summit of Kīlauea. A portion of the lake margin (bottom left in photo) is formed by a perched levee. USGS photo by M. Patrick.

Color photograph of lava lake

A wider view of the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. Active surface lava remains mostly limited to the western side of the lake (right side in this photo). The western vent continues to have low fountaining set within the cone. USGS photo by M. Patrick.

Eruptive activity continues in Halema‘uma‘u crater, at the summit of Kīlauea. The west vent remains active with low fountaining in a slightly perched pond set within the cone. Lava pours through a short spillway into the lava lake. USGS image by M. Patrick.

Color photograph of volcanic vent

Lava exits the west vent in Halema‘uma‘u crater the morning of October 23, 2021. Simultaneously, lava fountaining at the vent is vigorous enough to send spatter up, over, and onto the outer margin of the cone. This process, spatter accumulation, is how the cone around the west vent formed and continues to grow. USGS photo by K. Mulliken.

A view of Halema‘uma‘u crater, at the summit of Kīlauea volcano, just after 6 a.m. HST on Saturday, October 23. Lava continues to erupt from the west vent into the lava lake at the base of the crater. Surface activity is limited to the west portion of the lake. USGS photo by K. Mulliken.

Color photograph of volcanic vent erupting

On the afternoon of Friday, October 22, 2021, the Halema‘uma‘u eruption continued in Kīlaueas summit caldera. The west vent fountains were measured at up to 23 meters (75 ft), viewed here around 2 p.m. HST looking to the west from a vantage point on the south rim of the crater. USGS photo by K. Lynn.
