Deep Underground Science and Engineering, EarlyView.The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Deep Underground Science and Engineering, EarlyView.Fault slip can occur ahead of the injection pressure front due to poroelastic stress. Our model captures the interaction of pressure, stress, and friction, providing new insights into injection‐induced seismicity and post‐injection fault slip. Shut‐in operations can either mitigate or accelerate seismic events depending on fault conditions and ...

Deep Underground Science and Engineering, EarlyView.Probabilistic natural gradient boosting and Gaussian process regression models accurately predict rate‐dependent rock strength across lithologies. Static strength and strain rate dominate, while geometric factors have minimal influence, enabling interpretable and uncertainty‐aware predictions for dynamic geomechanical applications. Abstract The dynamic

Aspects of high resolution marine seismics [PDF]
, 1995 Reflection seismic methods, widely used in the oil-exploration, can give detailed images of the earth's interior. Application of these methods with strongly enhanced resolution allows detailed imaging of the upper tens of meters of the subsurface ...

Deep Underground Science and Engineering, EarlyView.This study reveals the failure evolution characteristics of deep cross‐fault roadway surrounding rock under excavation support and periodic weighting. Periodic weighting readily induces fault activation, with the spatial distribution of failed rock masses being controlled by the fault strike and dip.

Seismics on a cold alpine saddle - limits and challenges [PDF]
, 2010 The Colle Gnifetti is a glacier plateau at about 4450 m altitude in the Monte Rosa, Swiss Alps. Due to the altitude and a mean annual air temperature of around -14°C hardly any melting occurs.

Marine seismics with a pulsed combustion source and Pseudo Noise codes [PDF]
, 2007 There has been an ongoing debate for years of how dangerous seismic surveys are with respect to marine life. Marine seismics is today dominated by airgun technology, where high energy is generated by a release of compressed air into the water.

Deep Underground Science and Engineering, EarlyView.The graphical abstract depicts the workflow for porous‐ and fractured‐media simulations, where stochastically generated discrete natural fractures are required for the fracture‐media simulation. Abstract CO 2 ${\text{CO}}_{2}$ leakage is one of the main risks and barriers to geologic carbon storage. However, under the high‐temperature and high‐pressure

Basement Delimitation of the Taubaté Basin [PDF]
Geologia USP. Série Científica, 2011 The aim of this study is to define the basement map of the Taubaté Basin applying geostatistics to seismic, gravimetricand deep wells data. The study consisted of the interpretation of eleven seismic sections obtained in the central andnortheastern ...
