Landslide Activity in the European Alps ‐ Part 1: A Machine Learning Based Instrumental Catalog From the Analysis of Seismological Data

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Landslides in the European Alps are a growing concern in the context of climate change. However, landslide catalogs for the European Alps remain incomplete, often lacking precise timing and containing few, if any, entries for remote areas.

Stress analysis of crack characteristic of anthracite under dynamic loading

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 56-65, March 2026.
In this article, the dynamic compression test of anthracite under five strain rates is carried out, the evolution law of three kinds of crack characteristic stress is analyzed, and a prediction model of the crack characteristic stress threshold considering the strain rate effect is established. Then, the rationality of crack characteristic stress under

Dynamic Probabilistic Prediction of Rockburst Using a Dual‐Modality Model With Multisource Monitoring Data

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Rockburst, due to its suddenness, randomness, and harmfulness, is one of the main factors restricting the safe construction of deep underground engineering. To achieve accurate prediction of rockburst occurrence probability, a dataset for drilling and blasting (D&B) tunnel construction was established using microseismic (MS) and geological data ...

Study on the Influence of Coal Stress Damage on Impact Tendency Under Cyclic Loading and Unloading Effects

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This article aims to explore the response characteristics of coal impact tendency to cyclic load. Through the mechanical damage test of coal sample under cyclic load, the deformation and damage of the coal sample under different cyclic stress, cyclic rate, and cyclic times were analyzed.

Research on Stress Characteristics of Rockburst in Over-Length Deep-Buried Tunnel

Buildings
As a unique geological hazard in a high-geo-stress environment, rockburst happens with strong suddenness, randomness, and destructiveness, but the mechanism of its occurrence in a deep-buried tunnel in a high-geo-stress environment needs further study ...

The prevention of rockbursts in Gardanne colliery

, 1995
The Gardanne colliery lies between Aix-en-Provence and Marseille and is part of the south-east complex of H.B.C.M. (Subsidiary of the Charbonnages de France group). The coal deposit is from fluvio-lacustral origin and was formed some 75 millions years ago.
