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.

Experimental Investigation of Moisture Movement During Freeze–Thaw Cycles and Its Effect on Physical Rock Weathering in Low‐Porosity Alpine Limestone

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 354-371, July/September 2026.
ABSTRACT The progressive weakening of alpine rockwalls through subcritical cracking, driven by repeated low‐magnitude stress processes, plays a key role in alpine rock weathering. Laboratory studies using acoustic emission (AE) monitoring have shown that thermal stresses from freeze–thaw cycling induce crack propagation, with recent work highlighting ...

The Age and Origin of Block Deposits in the Victorian Alps, Australia

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 391-415, July/September 2026.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

Deciphering Freeze–Thaw Dynamics In Rockwalls: A Novel Approach for High Accuracy Regional‐Scale Modeling

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 430-448, July/September 2026.
ABSTRACT Using a large and novel array of instruments on five rockwalls in northern Gaspesia, their respective surface energy balances were calculated and their thermal regimes were measured and modeled to depths exceeding the seasonal frost penetration.

Multiproxy Chronologies of the Hurd Rock Glacier (Livingston Island, South Shetland Islands, Maritime Antarctica): Between the Late‐Stage Stabilization and Flow Deceleration

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 535-550, July/September 2026.
ABSTRACT The Hurd Rock Glacier, located on Livingston Island (South Shetland Islands archipelago, Maritime Antarctica), is a tongue‐shaped feature composed of angular boulders, displaying transverse ridges and furrows, and featuring lobate structures, which are more prominently developed in its frontal sector.

Amplification of Outburst Floods During Cascading Landslide Dam Failures: Insights From Numerical and Experimental Modeling

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Landslide dam failures can trigger catastrophic outburst floods in downstream regions. During cascading dams' failure, a notable amplification in flood magnitude is often observed. However, the mechanisms and influencing factors behind this amplification effect remain unclear.

Post‐Eruptive Deformation and Faulting Caused by Dike Channel Retraction, Material Drain‐Back and Contraction of the 2021 Tajogaite Craters (La Palma)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Young scoria cones fed by dike channels or conduits may undergo rapid and substantial post‐eruptive morphological modification; however, the structural controls and mechanisms governing topographic degradation remain poorly constrained. This knowledge gap limits our ability to reliably interpret topography, faults, deposits and the evolution ...
