Life and death of slow-moving landslides

P Lacroix, AL Handwerger, G Bièvre - Nature Reviews Earth & …, 2020 - nature.com
In the most destructive and catastrophic landslide events, rocks, soil and fluids can travel at
speeds approaching several tens of metres per second. However, many landslides …

[HTML][HTML] Highly variable friction and slip observed at Antarctic ice stream bed

TS Hudson, SK Kufner, AM Brisbourne, JM Kendall… - Nature …, 2023 - nature.com
The slip of glaciers over the underlying bed is the dominant mechanism governing the
migration of ice from land into the oceans, with accelerating slip contributing to sea-level …

Landslide sensitivity and response to precipitation changes in wet and dry climates

AL Handwerger, EJ Fielding… - Geophysical …, 2022 - Wiley Online Library
Slow‐moving landslides are hydrologically driven. Yet, landslide sensitivity to precipitation,
and in particular, precipitation extremes, is difficult to constrain because landslides occur …

[HTML][HTML] Complementary approaches towards a universal model of glacier surges

Y Terleth, WJJ Van Pelt, VA Pohjola… - Frontiers in Earth …, 2021 - frontiersin.org
Although many convincing, diverse, and sometimes competing models of glacier surging
have been proposed, the observed behavior of surging glaciers does not fit into distinct …

A consistent framework for coupling basal friction with subglacial hydrology on hard‐bedded glaciers

A Gilbert, F Gimbert, K Thøgersen… - Geophysical …, 2022 - Wiley Online Library
Below hard‐bedded glaciers, both basal friction and distributed subglacial drainage are
thought to be controlled by a network of cavities. Previous coupled hydro‐mechanical …

[HTML][HTML] InSAR-based characterization of rock glacier movement in the Uinta Mountains, Utah, USA

G Brencher, AL Handwerger, JS Munroe - The Cryosphere, 2021 - tc.copernicus.org
Rock glaciers are a prominent component of many alpine landscapes and constitute a
significant water resource in some arid mountain environments. Here, we employ satellite …

Enthalpy balance theory unifies diverse glacier surge behaviour

DI Benn, IJ Hewitt, AJ Luckman - Annals of Glaciology, 2022 - cambridge.org
It is commonly asserted that there are two distinct classes of glacier surges: slow, long-
duration 'Svalbard-type'surges, triggered by a transition from cold-to warm-based conditions …

Shear dilation of subglacial till results in time-dependent sliding laws

KLP Warburton, DR Hewitt… - Proceedings of the …, 2023 - royalsocietypublishing.org
The dynamics of glacial sliding over water-saturated tills are poorly constrained and difficult
to capture realistically in large-scale models. Experiments characterize till as a plastic …

A Machine Learning Framework to Automate the Classification of Surge‐Type Glaciers in Svalbard

C Bouchayer, JM Aiken, K Thøgersen… - Journal of …, 2022 - Wiley Online Library
Surge‐type glaciers are present in many cold environments in the world. These glaciers
experience a dramatic increase in velocity over short time periods, the surge, followed by an …

Transient evolution of basal drag during glacier slip

LK Zoet, NR Iverson, L Andrews, C Helanow - Journal of Glaciology, 2022 - cambridge.org
Glacier slip is usually described using steady-state sliding laws that relate drag, slip velocity
and effective pressure, but where subglacial conditions vary rapidly transient effects may …
