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.](https://d9-wret.s3.us-west-2.amazonaws.com/assets/palladium/production/s3fs-public/styles/masonry/public/thumbnails/video/20210728-Townsend-Thumbail.jpeg?itok=sYW2k7_9)
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.

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.

The eruption in Halema`uma`u crater, at the summit of Kilauea, is no longer active.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.
