Photo and Video Chronology – Kīlauea – April 8, 2022

By Hawaiian Volcano Observatory April 8, 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.

Recent changes in the Kīlauea summit eruption have seen the crusting-over of the lava pond near the western end of the Halema‘uma‘u crater floor. This view of the lava pond vicinity was captured through the lens of a laser rangefinder on April 6, 2022, from the western rim of the crater. Although the pond is crusted over, the continued presence of molten lava beneath the surface is evidenced by two glowing openings at either end of the pond, which scientists observed to be ejecting low-level spatter every few seconds. The pond measures approximately 25 meters (82 feet) from its northern (lower-left) to southern (upper-right) end. USGS image by M. Zoeller.

Unoccupied aircraft systems (UAS) flights on April 6, 2022, allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. The active lake surface is limited to the western portion of the crater. The scale of the thermal map ranges from blue to red, with blue colors indicative of cooler temperatures and red colors indicative of warmer temperatures. USGS has special use permits from the National Park Service to conduct official UAS missions as part of HVO’s mission to monitor active volcanoes in Hawaii, assess their hazards, issue warnings, and advance scientific understanding to reduce impacts of volcanic eruptions.
