Halema‘uma‘u lava lake, Kīlauea summit - September 30, 2021

Halema‘uma‘u lava lake, Kīlauea summit - September 30, 2021

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.

Infrastructure on ice – when road rides on accelerating rock glacier

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.

Contrib. of Rock-Mass Strength to Topographic Form and Post-Fire Eros.

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.

Ferromanganese Nodules—2021 North Atlantic Stepping Stones Exped. (AD)

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.

In 2015, the Washington Geological Survey received legislative funding to start a Landslide Hazards Program (LHP). The LHP has three primary functions: landslide inventory mapping, post-wildfire debris flow assessments, and emergency response.
