The effusive eruption of the volcano continues and no significant change in activity has occurred since the last update.
The western portion of the lava lake in Halema'uma'u crater remains active and is supplied by the lava flow from the western fissure of the spatter cone. A small incandescent opening at the top of the west vent spatter cone is visible in the attached image.
The inactive eastern portion of the lake appears dark.
Sulfur dioxide (SO2) emissions remain at elevated levels and reached to a 1000 tonnes/day on 3 March as a result of the ongoing eruption. Volcanic gas emissions from the active west vent are being transported to the southwest.
On 4 March, HVO scientists conducted an overflight of Kīlauea's summit to document the ongoing eruption.
Laser rangefinder measurements indicate that lava has filled about 220 meters (772 ft) of Halema'uma'u.

Kilauea volcano (Hawaiian Islands, USA) - Smithsonian / USGS Weekly Volcanic Activity Report for 3 February-9 February 2021 (Continuing Activity)

HVO reported that lava from a vent on the inner NW wall of Kilauea's Halema`uma`u Crater streamed down the cone into a perched lava lake during 3-9 February. The western half of the lake dropped from 213 m on 3 February to 211 m on 4 February and stayed at that level during 5-6 February; the drop in lake level was likely the result of summit deflation that was detected by tiltmeters. The lake level had risen to 214 m by the morning of 7 February coincident with the onset of summit inflation. ... Read all
