Gaborlet‐guided sparse filtering: A novel intelligent method for lithology identification by vibration signals while drilling

open access: yesDeep Underground Science and Engineering, EarlyView.
The flowchart illustrates rock specimen testing, vibration signal acquisition, and feature extraction with Gaborlet and sparse filtering for classification. Abstract Traditional lithology identification methods mainly rely on core sampling and well‐logging data.

Minnesota at a Glance Earthquakes in Minnesota

open access: yes, 1994
Short summary of earthquakes in Minnesota, issued in 1994, updated 2014, 2020.Few natural phenomena attract as much public attention as earthquakes. Seldom does a month go by that we do not hear of a destructive earthquake somewhere in the world.

Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

open access: yesDeep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Coseismic slip distribution of the 2024 Noto Peninsula earthquake deduced from dense global navigation satellite system network and interferometric synthetic aperture radar data: effect of assumed dip angle

open access: yesEarth, Planets and Space
The Mw 7.5 Noto Peninsula earthquake, which occurred on January 1, 2024, was considerably hazardous to the peninsula and surrounding regions owing to a strong motion, large-scale crustal deformation, and subsequent tsunami.

Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

open access: yesDeep 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.

Significant afterslip contribution to postseismic deformation in Sado Island following the 2024 Noto Peninsula earthquake: insights from two dense GNSS observation networks

open access: yesEarth, Planets and Space
This study investigated postseismic deformation resulting from the 2024 Noto Peninsula earthquake on January 1. Particular focus was placed on the displacement observed in Sado Island, which is located several tens of kilometers east of the eastern end ...

Numerical simulation study on the evolution of the temperature field and frozen wall in fractured rock mass

open access: yesDeep 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
