Lava fountains through the lava lake in Halema‘uma‘u, at Kīlauea's summit, create waves or ripples in the lake surface. The ripples are visible on the surface as thin crustal plates move apart and back together again as the wave motion passes by (like inner tubes in a crowded wave pool), creating a moving arc of increased glow.

A new Kīlauea summit eruption within Halema‘uma‘u crater began at approximately 3:20 p.m. HST on September 29, 2021, with fountains appearing on the central crater floor, where a lava lake had been active from December 2020 until May 2021. Just after 4:40 p.m., a new vent opened on the west wall of the crater, and the initial moments were captured in this video.

During July, Yellowstone caught everyone’s attention with 1,000+ earthquakes located in seven distinct earthquake swarms. The largest swarm occurred beneath Yellowstone Lake and had 764 earthquakes, the largest of which was a Magnitude 3.6.

The eruption in Halema`uma`u crater, at the summit of Kilauea, is no longer active. The lava lake that was active between December 2020 and May 2021 remains solidified at the surface. A routine summit overflight observed no signs of residual incandescence in cracks, and only a diffuse gas plume rising from the northern portion of the lake.

Yellowstone Volcano Observatory scientist-in-charge Mike Poland provides the YVO monthly update from the rim of Yellowstone’s Grand Canyon. The V-shaped gorge tells an amazing geologic story. About half a million years ago, a large rhyolite lava flow erupted. Over time, hot water and gases heated by the magma chamber rose through faults in the lava flow.

The area of active surface lava has diminished over the past month in Halema`uma`u crater, at the summit of Kilauea. Today, active surface lava was limited to a small pond, about 20 meters (yards) long. The pond surface was normally covered with a stationary crust, but occasionally resurfaced. This video shows crustal foundering during a resurfacing event.

The lava lake in Halemaʻumaʻu crater, at the summit of Kīlauea, remains active but has diminished in area and vigor over the past month. This thermal timelapse sequence shows the changes in the lake activity over the past month. In mid-April the area of active surface lava in the lake was approximately 7.5 acres (3 hectares).

It's May, the snow is melting and the roads are mostly open, so it's time for geologists, geophysicist and geochemists to head into Yellowstone to start projects they have been planning for the last several months. Next week, a field team will deploy a temporary GPS network to help “densify” the network of continuous GPS stations already in place.

The 1980 eruption of Mount St. Helens was monumental in so many different ways. It had a huge impact on the geography of southwestern Washington, ash affected many people, lives were lost, and lessons were learned. The eruption also led to the creation of the USGS Cascades Volcano Observatory in Vancouver, Washington.
