Deep Underground Science and Engineering, EarlyView.This research proposes an interpretable hybrid stacking ensemble framework, optimized by the Sparrow Search Algorithm, to enhance hard rock pillar stability prediction. By integrating six machine learning models—k‐nearest neighbors, support vector machines, random forests, Gradient Boosting Decision Tree, eXtreme Gradient Boosting, and Light Gradient ...

Geophysical Research LettersObservations of the 2019 magnitude 7.1 Ridgecrest, California, earthquake indicate a relatively slow rupture (∼2 km/s). The fault is surrounded by sedimentary rocks and low‐velocity damage zones, which can amplify ground motions but also slow down ...

Spontaneous complexity in the dynamics of slow laboratory earthquakes.
Nature CommunicationsRock deformation experiments play a key role in our understanding of earthquake physics and friction constitutive laws. These laws commonly describe the response of analogue laboratory faults as a simple and homogeneous system, without accounting for the spatial-temporal evolution of structures in the sample.

Deep Underground Science and Engineering, EarlyView.This paper presents temporal and adaptive‐frequency network with MixStyle (TAMNet), a deep time‐series modeling framework for accurate and robust multi‐well oil productivity forecasting. TAMNet integrates transformer and long short‐term memory architectures to capture both short‐ and long‐term temporal dependencies, enhanced by a temporal gate unit ...

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.

The role of epsilon for the identification of groups of earthquake inputs of given hazard
, 2008 Response spectra have been used in the years not only to obtain estimations of the seismic response for given dynamic system in response spectral analysis, but also as a useful reference for the identification of design time-history inputs (when time ...

Deep Underground Science and Engineering, EarlyView.This study proposes an eco‐friendly coal permeability enhancement technique by utilizing mine waste gangue as an abrasive in high‐pressure water jets. Integrating erosion experiments with smoothed particle hydrodynamics‐finite element method coupled simulations, the research study elucidates the flow field dynamics and a nonlinear solid–liquid ...

Estimating Consumer Valuation of Earthquake Risk: Evidence from Japanese Housing Markets [PDF]
The relationships between seismic risk and rental and owner- occupied housing prices in the whole of Japan are examined. The empirical results from hedonic regressions with earthquake risk indices suggest that: (1) earthquake occurrence probability has a

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
