Daily measurement of slow slip from low-frequency earthquakes is consistent with ordinary earthquake scaling [PDF]
, 2019 Slow slip transients on faults can last from seconds to months and stitch together the earthquake cycle. However, no single geophysical instrument is able to observe the full range of slow slip because of bandwidth limitations.

Deep Underground Science and Engineering, EarlyView.Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Deep Underground Science and Engineering, EarlyView.The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in

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.

Similar scaling laws for earthquakes and Cascadia slow-slip events [PDF]
, 2019 Faults can slip not only episodically during earthquakes but also during transient aseismic slip events, often called slow-slip events. Previous studies based on observations compiled from various tectonic settings have suggested that the moment of slow ...

Deep Underground Science and Engineering, EarlyView.A novel shear‐lag model, validated by pull‐out tests, incorporates a constant bond stress stage to predict the complete load–displacement response of grouted rock bolts, providing a new tool for optimizing anchorage length and material toughness in deep underground engineering. Abstract The stability of rock masses in deep underground excavations, such

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 ...
