Photo and Video Chronology – Kīlauea – April 1, 2021

Release Date:

Kīlauea's summit eruption continues on the Island of Hawai‘i; Halema‘uma‘u west vent erupts lava into the lava lake, which was 224 m (735 ft) deep this morning, April 1. 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

This March 31, 2021, photo shows a close-up view of the active western fissure of Halema‘uma‘u at Kīlauea volcano on the Island of Hawai‘i. Near the bottom of the photo, orange incandescence can be seen from two circular vents of the spatter cones. The orange area above the vents is where lava is entering the lava lake, and the orange area in upper right side of the photo is an area of foundering within the lava lake. This photo was taken at 1:52 p.m. HST from the western rim of Halema‘uma‘u crater. USGS photo by J.M. Chang.

The lava lake remains active in Halema‘uma‘u Crater, at the summit of Kīlauea. This video shows the inlet where lava from the western fissure is supplied to the lake. The motion of the lava stream is sluggish, and this video is shown at 20x speed.
