First Empirical Assessment of Ice Content From a Himalayan Rock Glacier

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Climate warming and degradation of glaciers and permafrost in High Mountain Asia is threatening the sustainability of the region's natural “water towers” and allied ecosystems and infrastructure. Approximately 25,000 Himalayan rock glaciers exist and, being more resilient to climatic change than glaciers, they represent important freshwater ...

GIS-Based Rockfall Susceptibility Zoning in Greece

open access: yesGeosciences, 2019
The assessment of rockfall risks on human activities and infrastructure is of great importance. Rock falls pose a significant risk to (a) transportation infrastructure, (b) inhabited areas, and (c) Cultural Heritage sites.

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

open access: yesJournal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

18-years of high-Alpine rock wall monitoring using terrestrial laser scanning at the Tour Ronde east face, Mont-Blanc massif

open access: yesEnvironmental Research Letters
Since the end of the 20th century, each decade has been warmer than the previous one in the European Alps. As a consequence, Alpine rock walls are generally facing high rockfall activity, likely due to permafrost degradation.

3D Analysis of a Fragmental Rockfall

open access: yes, 2020
Fragmentation in a rockfall event influence the total number of fragments, the mass distribution, and the impact energies and runouts. Then, the probability of impact and hazard characterization should consider fragmentation. A fractal fragmentation model has been proposed in order to reproduce the phenomenon.

Multi‐Temporal UAV Surveys and Modelling of Soil Erosion in the Ca l'Isard Catchment, NE Spain

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 5, September–October 2026.
ABSTRACT This study investigates seasonal sediment dynamics in highly active Mediterranean mountain badlands by integrating multi‐temporal Uncrewed Aerial Vehicle (UAV) surveys, and landscape evolution modelling (LEM) in the Ca l'Isard catchment (NE Spain).

Temperature fluctuations controlled episodic rockfall activity in the Rwenzori Mountains (Uganda) during the Holocene

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
The alignment between rockfall deposit surface exposure 10Be ages and Holocene temperature records suggests that major rockfall events occurred episodically in response to climatic fluctuations. We conclude that temperature and its evolution enabled mechanical, chemical or bio‐chemical enhancement of fracture progression.

Dynamics of Rockfalls in Sri Lanka and Landslide Hazards [PDF]

open access: yes, 1993
The paper spotlights the dynamics of rockfalls and debrisflows in Sri Lanka in the backdrop of some recent examples and discusses the appropriateness of simple energy dissipation systems in situations where source of rockfall is either intractable or ...

Leveraging Internet News-Based Data for Rockfall Hazard Susceptibility Assessment on Highways

open access: yesFuture Internet
Over three-quarters of Taiwan’s landmass consists of mountainous slopes with steep gradients, leading to frequent rockfall hazards that obstruct traffic and cause injuries and fatalities. This study used Google Alerts to compile internet news on rockfall
