February 4, 2021 — Kīlauea

On February 4, HVO geologists observed brief heavy rainfall on the lava lake within Halema‘uma‘u crater at the summit of Kīlauea. The rain flashed to thick white steam as it hit the hot lava surface. The western vent, visible in the lower left, continued to supply lava to the western active portion of the lava lake. USGS photo taken by J. Schmith from the west rim of

View of lava lake in Halema‘uma‘u — Kīlauea summit — Feb. 3, 2021

View of the lava lake in Halema‘uma‘u from the western rim of the crater, looking eastward. Volcanic gases emitted from the western fissure obscure the built-up spatter cone. The active western portion of the lake (lower) has a silvery grey color, while the stagnant eastern portion of the lake (upper) is a dark duller grey. The main island is prominent within the active

Aerial of Halema‘uma‘u Crater, Kīlauea Volcano's Summit

Eruptive activity continues at the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. This video was taken on February 1 from the morning helicopter overflight. The western fissure supplies lava to the lake at an inlet site along the west lake margin. Activity has been stable in recent days with no major changes.

The dull black color on the eastern (lower left) portion of the lava lake is the inactive surface. The more reflective silver surface is the western (upper right) active portion of the lava lake, with the gas plume marking the location of

Rockfall debris on lava lake surface crust—Kīlauea summit eruption

Rockfalls have been a frequent occurrence in Halema‘uma‘u crater, both before and during the current eruption. Debris from a recent rockfall can be seen sitting on the solidified lava lake crust (center). The crust on the southern edge of the lava lake is thick enough to support the weight of the boulders that have fallen. USGS photo taken by B. Carr on February 1 during a

Eruptive activity continues within Halema‘uma‘u crater—Kīlauea summit

The lava lake within Halema‘uma‘u crater, at the summit of Kīlauea, remains active. An HVO geologist uses a laser rangefinder to measure the elevation of various spots on the lava lake surface. Today (February 2), the active, western portion of the lake was about 213 m (699 ft) deep. HVO scientists continue to monitor the eruption from an area of Hawai‘i Volcanoes National

Eruption overflight on February 1, 2021—Kīlauea

No major changes were observed at the lava lake in Halema‘uma‘u crater during yesterday's helicopter overflight. Eruptive activity continues from the western fissure, with active surface lava largely confined to the western half of the lake. USGS photo by M. Patrick.

A closer view of the lava lake in Halema‘uma‘u crater from the helicopter. Most of the lake surface in the foreground (east) is solidified on the surface, with active lava limited to the western end of the lake, in the distance. Rockfall debris can be seen on the southern margin of the lake (left side of photo). USGS photo by M. Patrick.

Eruptive activity continues in Halema‘uma‘u crater, at Kīlauea summit

Eruptive activity continues in Halema‘uma‘u crater, at the summit of Kīlauea. The active surface lava remains largely confined to the western (left) portion of the lava lake. As of the afternoon of January 31 lava had filled about 212 m (695 ft) of Halemaʻumaʻu in the active western portion of the lava lake. USGS photo by M. Patrick.

In the center, a lobe of surface lava is moving south (towards the bottom of the photo) as surface crust founders along its leading edge. Just below the center point of the photo a terracing can be seen marking the front of previous advancing, overlapping lobes in this area. On
