A review on rockburst prediction and prevention to shape an ontology‐based framework for better decision‐making for underground excavations

Deep Underground Science and Engineering, EarlyView.
A scientometric analysis of 2449 journal articles and a comprehensive review of 336 papers were conducted, discussing and identifying challenges and research gaps in rockburst prediction and prevention and proposing an ontology‐based framework for better decision‐making in underground excavations. Abstract With underground engineering projects becoming

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

Deep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Active tectonics in the Kenya Rift

, 2022
Magmatische und tektonisch aktive Grabenzonen (Rifts) stellen die Vorstufen entstehender Plattengrenzen dar. Diese sich spreizenden tektonischen Provinzen zeichnen sich durch allgegenwärtige Abschiebungen aus, und die räumliche Verteilung, die Geometrie, und das Alter dieser Abschiebungen lässt Rückschlüsse auf die räumlichen und zeitlichen ...

Active Tectonics and Alluvial Rivers [PDF]

Eos, Transactions American Geophysical Union, 2002
Flying into San Francisco, California, for the AGU Fall Meeting from the east coast of the United States, one sees an ever‐changing pattern of rivers below. From straight channels, the rivers take on a meandering pattern, become braided, and form oxbow lakes.

On the origin of the North Pacific arcs [PDF]

, 2004
We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean.

Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

Deep Underground Science and Engineering, EarlyView.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

Deep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Reevaluating historical tsunami hazards from the Makran subduction zone and local seismic sources along the Western Indian margin through numerical modelling

Geoscience Letters
The western coast of India is highly vulnerable to tsunami hazards due to its geographical proximity to the Makran Subduction Zone (MSZ), one of the most seismically active margins of the northern Indian Ocean.

Deformation of continental crust along a transform boundary, Coast Mountains, British Columbia [PDF]

, 2010
New structural, paleomagnetic, and apatite (U-Th)/He results from the continental margin inboard of the Queen Charlotte fault (~54°N) delineate patterns of brittle faulting linked to transform development since ~50 Ma.
