The eruption continues in Halema‘uma‘u crater, at the summit of Kīlauea. This video shows the dominant fountain at the west vent, from two different angles, as well as the smaller fountaining source emerging through the lava lake.

Lava fountains through the southern part of the lava lake in Halema‘uma‘u, at Kīlauea's summit during the ongoing eruption. Sustained fountain heights from this fissure ranged from about 5–10 meters (16–33 ft) with occasional higher bursts of spatter. This video clip was recorded on October 2, 2021, from the southern crater rim.

Lava fountains from the western fissure vent in the Halema‘uma‘u crater wall, at Kīlauea's summit during the ongoing eruption. Sustained fountain heights from this fissure ranged from about 10–15 meters (33–49 ft) with occasional higher bursts of spatter. This video clip was recorded on October 2, 2021, from the western crater rim.

Low lava fountains near the southeast edge of the main island in the Halema‘uma‘u lava lake, during the ongoing Kīlauea summit eruption. One of the small (less than 5 meters or 16 feet) fountains has built a cone on the edge of the island.

An eruption in Halema‘uma‘u crater, at the summit of Kīlauea, began yesterday afternoon and continues this morning. During an overflight at approximately 7:30 a.m. HST on September 30, 2021, several fountaining sources were active in the crater, including those in the lake center and on the west wall. USGS video by M. Patrick.

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.

The 92-mile, dead-end Denali Park Road crosses an accelerating rock glacier. Until 2014, the rock glacier would only displace the road a few tens of centimeters per year, however during the summer of 2021 the rock glacier has moved the road almost 40 cm/day.

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, creating a new lava lake. This video shows the dominant fountain, south of the lake center, on the evening of September 29, 2021. USGS video by M. Patrick.

We sometimes fall back on an implicit model that post-wildfire debris flows are only triggered once a certain level of saturation or rainfall is reached, and that the sediment supply is soon exhausted and future flows are unlikely until it recharges.

Rock-mass strength is typically assumed to influence geomorphic processes by setting the erodibility of landscapes. However, the contribution of rock-mass strength to topographic form is often overlooked, largely because rock-mass strength is challenging to quantify over the broad spatial scales relevant to geomorphology.

During a recent dive on the New England Seamount chain off the North Atlantic coast, researchers aboard the NOAA Ocean Exploration Expedition, North Atlantic Stepping Stones, discovered a marine geological feature known as a ferromanganese (Fe-Mn) nodule field in the saddle between two peaks of Gosnold Seamount.
