Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Automatic Crater Classification Using a Deep‐Learning‐Based Pipeline

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Identifying and classifying impact craters on Mars is crucial for understanding the planet's geological history and surface evolution. Traditional crater classification relies on manual annotation methods, which are often limited by human biases and the difficulty of interpreting geomorphological features.

A probabilistic approach to integrate the effect of protection systems into rockfall hazard assessment

, 2017
The paper introduces the essential features of a new strategy to develop reliable and computa-tionally cost-effective models of the mechanical response of a rockfall barrier subjected to realistic impact conditions. The approach combines the use of three-

First Empirical Assessment of Ice Content From a Himalayan Rock Glacier

Geophysical 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 ...

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

Journal 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 ...

Study on the method of estimating the volume of fragmental rockfall based on image recognition

Shuiwen dizhi gongcheng dizhi
There are frequent cataclastic rockfall disasters in southwest mountainous areas. To accurately simulate the process of rockfall movement and quantify the risk of rockfall, it must first determine the volume of rockfall.

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

European 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).

3D Analysis of a Fragmental Rockfall

, 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.

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

Earth 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.
