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The eruption in Halema`uma`u crater, at the summit of Kilauea, is no longer active.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

This video shows a typical day on Mauna Loa, captured from a new webcam looking south towards the volcano. The field of view covers the summit region and much of the Northeast Rift Zone.

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).

Jon Major, scientist-in-charge of the USGS Cascades Volcano Observatory, provides an overview of the major volcano hazards in the Cascades, the function and responsibilities of the Cascades Volcano Observatory, and a brief synopsis of what's been going on at Mount Baker, Glacier Peak, Mount Rainier, Mount Adams, Mount St.

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.

The lava lake in Halema‘uma‘u Crater, at the summit of Kīlauea Volcano, remains active. This video is shown at 30x speed and shows the lava supplying the lake from the western fissure, with scattered crustal foundering across the lake surface.
