By Kīlauea April 15, 2021

Kīlauea's summit eruption continues on the Island of Hawai‘i; Halema‘uma‘u west vent erupts lava into the lava lake, which was 227 m (745 ft) deep this morning, April 15. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear—monitor the eruption from with

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.

A close-up view of the western fissure within Halema‘uma‘u at the summit of Kīlauea Volcano, Island of Hawai‘i. Lava continues to enter the lava lake from a wide inlet near the base of the western vent (fuming at center right). Crustal foundering is common on the active lava lake surface (center bottom), located on the western side of the crater. This photograph was taken on April 14, 2021, at 1:53 p.m. HST from the south rim of Halema‘uma‘u, an area within Hawai‘i Volcanoes National Park that remains closed to the public due to safety reasons.

This video shows the inlet along the western margin of the lava lake in Halema‘uma‘u Crater, at the summit of Kīlauea. The lava stream was moving slowly but steadily, and was emerging beneath a portion of crust attached to the lake margin. The video is shown at 10x speed.

KPcam webcam on the flank of Mauna Loa looks south towards the summit of Kīlauea to monitor the gas plume from the active lava lake. This time-lapse video shows a typical day for the summit plume. Clear views in the night and morning show the low, ground-hugging plume carried to the southwest by the tradewinds. The plume is blocked from view by afternoon rain clouds. In the evening the clouds lift and the glow from the vent is visible again.
