Analysis on the geo-resistivity anomaly at Baoji Seismic Station of the Jiuzhaigou Ms7.0 earthquake

IOP Conference Series: Earth and Environmental Science, 2021
Abstract According to the geological structure and observation characteristics of Baoji Seismic Station, a variety of methods are used to process and analyze the geo-resistivity data of Baoji Seismic Station from 2014 to 2018, such as the fourier sliding method that removing annual variation, the anisotropic degree method of the geo ...

Rock Magnetic Responses to Creep and Stick‐Slip Deformation Processes in the Xianshuihe Fault Zone, Eastern Tibetan Plateau

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract The Xianshuihe fault zone (XSHF) in southwestern China accommodates both aseismic creep and seismic slip, yet geological evidence constraining these processes remains limited. Hence, we conducted microstructural, geochemical, and rock magnetic analyses of fault‐zone materials from the Cuoniulongba River outcrop.

Experimental Simulation Investigation on Mechanism and Criterion of Impact‐Induced Rockburst in Gaoloushan Deep Tunnel

Energy Science &Engineering, Volume 13, Issue 8, Page 4252-4266, August 2025.
ABSTRACT During the excavation of a deep‐buried tunnel by the drilling and blasting method, the dynamic stress of blasting may cause the disorderly release of high energy in the rock mass during the blasting process of deep high‐energy rock. Blasting vibration is one of the main factors inducing dynamic disasters (such as rockbursts) in the surrounding

Slip Deficit Rate and Seismic Potential on Crustal Faults in Tibet

Geophysical Research Letters, Volume 52, Issue 1, 16 January 2025.
Abstract Quantifying slip deficit rates on active faults in Tibet is essential for understanding fault kinematics and assessing seismic hazards, but has not been fully characterized, particularly on secondary faults. In this study, we integrate an updated interseismic Global Navigation Satellite Systems velocity field from 4,458 stations across ...

Characteristics of Thermal Infrared Anomalies during the Earthquakes in Wenchuan, Lushan in Ya’an and Jiuzhaigou

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Satellite thermal infrared observation has advantages over other earthquake observation techniques. With MODIS remote-sensing images from the TERRA satellite, the thermal infrared brightness temperature difference variation rate was used to analyze the observation data prior to three Magnitude-7-and-above earthquakes along the ...
