Photo and Video Chronology – Kīlauea – February 22, 2021

By Kīlauea February 22, 2021

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&lsq

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.

HVO geologists use a laser rangefinder to measure the distance to the Halema‘uma‘u lava lake, and other eruptive features, at the summit of Kīlauea Volcano. These lava lake measurements are used to help calculate the depth, volume, and how it has evolved throughout the eruption. The stagnant eastern portion of the lava lake is visible in the lower-left.

This video shows a close-up of the small inlet where lava enters the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. The inlet consists of a small upwelling zone, with lava rapidly developing a thin flexible crust as it moves away from the source.
