Urban Basin Structure Imaging in Northern Los Angeles From Ambient Noise Differential Adjoint Tomography

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract We employ differential adjoint tomography to suppress the effects of uneven noise sources and image the upper crust S wave velocity structure of San Gabriel Basin, Chino Basin and San Bernardino Basin in the northern Los Angeles. A Sequential Subdomain Inversion strategy is implemented to address regional imbalance of sensitivity kernel ...

Induced Earthquakes Inhibited by Shear Thickening Fluid

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Induced seismicity is an inevitable consequence of subsurface resource development. Public concerns have been raised in cases where a surge in felt or damaging earthquakes has occurred because of industrial activity. The effective mitigation of induced earthquakes remains a major challenge despite the employment of several strategies. Here, we

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.

Microseismic monitoring and numerical simulation on the stability of high-steep rock slopes in hydropower engineering

Journal of Rock Mechanics and Geotechnical Engineering, 2015
For high-steep slopes in hydropower engineering, damage can be induced or accumulated due to a series of human or natural activities, including excavation, dam construction, earthquake, rainstorm, rapid rise or drop of water level in the service lifetime

Quantitative Evaluation of the “Non-Enclosed” Microseismic Array: A Case Study in a Deeply Buried Twin-Tube Tunnel

Energies, 2019
The high-stress hazards of underground engineering have stimulated the exploration of microseismic monitoring and early warning methods. To achieve a good monitoring effect, the monitoring object is usually enclosed by a microseismic array (sensor array)

The Optimum Wavelet Base of Wavelet Analysis in Coal Rock Microseismic Signals

Advances in Mechanical Engineering, 2014
Coal rock rupture microseismic signal is characterized by time-varying, nonstationary, unpredictability, and transient property. Wavelet transform is an important method in microseismic signals processing. However, different wavelet bases yield different
