Distinguishing damages from two earthquakes —Archaeoseismology of a Crusader castle (Al-Marqab citadel, Syria) [PDF]
, 2010 Damages from two major earthquakes are identified in medieval Al-Marqab citadel (Latin: Margat) in coastal Syria. Built by the Order of St. John (Hospitallers) in the twelfth–thirteenth centuries, the hilltop fortification has masonry walls made with and

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology
Deep Underground Science and Engineering, EarlyView.This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

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

Experimental evidence of seismic ruptures initiated by aseismic slip
Nature CommunicationsSeismic faults release the stress accumulated during tectonic movement through rapid ruptures or slow-slip events. The role of slow-slip events is crucial as they impact earthquakes occurrence.

Deep Underground Science and Engineering, EarlyView.The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Shallow very-low-frequency earthquakes accompany slow slip events in the Nankai subduction zone
Nature Communications, 2018 Slow earthquakes are now increasingly recognised to occur at plate boundaries globally. Here, the authors examine seafloor observational data from the Nankai trough and find that very-low-frequency events and slow-slip events frequently occur together ...

Quantifying the Role of 3D Fault Geometry Complexities on Slow and Fast Earthquakes
Geophysical Research LettersTraditional models of slow slip events (SSEs) oversimplify fault geometry, although imaging shows subduction faults are segmented and complex. We examine how fault interactions control slip behavior using 3D quasi‐dynamic simulations of two parallel ...
