Kīlauea images of eruptive activity, field work, and more.
Early this morning, the west vents in Halema‘uma‘u spattered from two places at the top of a small cone plastered on the northwest wall. This process can be seen in Kīlauea Volcano's summit F1 thermal webcam view of the lava lake.

At Halema‘uma‘u, the west vents (visible in the foreground of this photo as two glowing holes on a cone-shaped feature) erupt occaisional spatter.

The west vent in Halema‘uma‘u crater continues to erupt at Kīlauea’s summit. These telephoto images from December 29 (left) and December 30 (right) compare the lava lake surface below the west vent. The west vent is supplying lava to the lake through a crusted over channel, which was starting to form by December 30. USGS photos by H. Dietterich.

The KW webcam captured this image of Kīlauea's ongoing summit eruption, which continued overnight. The KW webcam looks in an east direction; north is to the left in the photo, south to the right, west to the bottom, and east to the top. This photo, taken at 6:30 a.m.

The margins of the lava lake in Halema‘uma‘u are showing a subtle levee around the perimeter. The levees grow from repeated small overflows, and the rafting and piling of pieces of surface crust that fuse together into a barrier that impounds the lake.

Telephoto view of the west vent area in Halema‘uma‘u, Kīlauea Volcano. The west vents are in the northwestern wall of Halema‘uma‘u crater; intermittent spattering at the vents has constructed a perched pointed cone on the crater wall. USGS photo by M. Patrick.

With the onset of the eruption at Kīlauea summit on December 20, 2020, the HVO monitoring network has been recording volcanic tremor, a signal that travels through the subsurface as magma degasses and erupts from vents to fill a lava lake at the summit.

Kīlauea's summit lava lake in Halemaʻumaʻu continues to re-surface. This process is called crustal foundering, in which pieces of solidified lava crust on the surface of the lava lake break and sink back into the liquid portion. USGS photo by M. Patrick.

On January 1, 2021, with permission from Hawai‘i Volcanoes National Park, HVO researchers set up temporary seismic instruments around Halema‘uma‘u crater to collect data that will help them learn more about how magma travels in the shallow magmatic plumbing system beneath Kīlauea Volcano.

Over the past week, the lava lake in Halema‘uma‘u has developed a subtle levee around its perimeter that allows the lake to be slightly perched above its base, like a mesa. The levees grow from repeated small overflows, and the rafting and piling of pieces of surface crust that fuse together into a barrier that impounds the fluid lake.

Kīlauea's summit lava lake in Halemaʻumaʻu is continually re-surfacing. Like the 2008-2018 lava lake, the current lava lake is exhibiting crustal foundering, when fragments of solidified lava crust on the surface break and sink back into the liquid portion. USGS photo by M. Patrick.

Kīlauea eruption in Halema‘uma‘u on Jan. 1, 2021. The channel-like feature remains visible on the lava lake surface within Halemaʻumaʻu crater at Kīlauea Volcano's summit. This feature originates from the influx of lava from the western fissure. USGS photo by M. Patrick.

Within an hour of the Kīlauea summit eruption starting on December 20, 2020, HVO's permanent seismic network detected a signal called volcanic tremor.

The western fissure in Halemaʻumaʻu wall remains active. Glowing vents and a prominent spatter cone are visible in this photo, which shows some spattering at the vent. This view looks steeply down from Kīlauea's west caldera rim, and the lava lake surface is visible in the background. USGS photo by B. Carr on 12/31/2020.
