Photo and Video Chronology – Kīlauea – February 18, 2022

By Kīlauea February 18, 2022

An eruption at Kīlauea's summit began at approximately 3:20 p.m. HST on September 29, 2021. Intermittent lava activity is confined within Halema‘uma‘u crater, in the closed area of Hawai‘i Volcanoes National Park.

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.

Eruptive activity at the summit of Kīlauea, within Halema‘uma‘u crater, has recently been characterized by the eruption waxing and waning over timescales of days. This video, captured from February 7–10, 2022, by the F1cam, a thermal camera located on the west rim of the caldera and looking east, shows the eruption pass through a pause cycle. Other eruption monitoring data streams also track this fluctuating activity, with ground deflation and decreased volcanic sulfur dioxide emissions coinciding with decreased and paused eruption activity.

February 18, 2022 — Kīlauea summit

Color photograph of lava — On Friday, February 18, Hawaiian Volcano Observatory scientists visited the Halema‘uma‘u crater rim to observe the ongoing Kīlauea summit eruption. At the time of their visit, the lava lake in the western portion of the crater had drained substantially in association with deflation of the summit region. In this photo captured through the lens of a laser rangefinder device, the residual lava pond that has remained active through recent eruptive pauses is visible just above and left of center. The lava pond feeds a weak lava flow through a deeply-incised channel (center) to the main lava lake (lower-right), which is sitting at a very low level relative to the surrounding levees; the levees in this view stand approximately 10 meters (33 feet) tall. The west vent spatter cone is just out-of-view to the left of this image. USGS photo by M. Zoeller.
