Exploring seismic warning thresholds for vehicle-track systems through combined shaking table tests and dynamic numerical simulations

Scientific Reports
This study conducted vehicle-track shaking table model tests at the Seismic Laboratory of the China Academy of Building Research, employing both unidirectional (horizontal) and bidirectional (horizontal and vertical) seismic waves.

Analysis and application of low frequency shadows based on the asymptotic theory for porous media

Scientific Reports
Low-frequency shadows beneath gas reservoirs can be regarded as a time delay relative to the reflection from the reservoir zone, but they cannot be reasonably explained by the high-frequency attenuation or velocity dispersion observed in normal P-waves ...

Jointed Rock Mass Effects on the Seismic Waves Scattering from the Canyon Sites in the Dam\'s Support

علوم آب و خاک, 2019
Seismic study of canyon sites has always been one of the important fields of seismic studies because of massive structures such as dams that are built in such sites.

Infrasound Unmasks Flow Turbulence as an Additional Seismic Source in Debris Flows

Geophysical Research Letters
Debris flows radiate both seismic and infrasonic waves. According to previous studies, seismic energy is generated by the solid particle collisions with the riverbed and is dominated by the boulder‐rich front, while infrasound is produced by turbulence ...
