Interferometric surface-wave isolation and removal [PDF]

, 2007
The removal of surface waves (ground roll) from land seismic data is critical in seismic processing because these waves tend to mask informative body-wave arrivals.

Separation of Body and Surface Wave Background Noise and Passive Seismic Interferometry Based on Synchrosqueezed Continuous Wavelet Transform

Applied Sciences
Passive seismic interferometry is a technique that reconstructs virtual seismic records using ambient noise, such as random noise or microseisms. The ambient noise in passive seismic data contains rich information, with surface waves being useful for the

Comparative structural response of two steel bridges constructed 100 years apart [PDF]

, 2011
This paper presents a comparative numerical analysis of the structural behaviour and seismic performance of two existing steel bridges, the Infiernillo II Bridge and the Pinhao Bridge, one located in Mexico and the other in Portugal. The two bridges have

Non-limit state seismic earth pressure solution for finite soil mass considering intermediate principal stress

Shenzhen Daxue xuebao. Ligong ban
To investigate the distribution law of non-limit state seismic passive earth pressure in a finite soil mass under the translational (T-mode) pattern of a rigid retaining wall, and to overcome the limitations of existing seismic earth pressure models that

Bond Formation: Shaken, Not Stirred

Chemistry – A European Journal, EarlyView.
Shaking of seismo‐molecules efficiently transforms kinetic energy into storable chemical potential, unlocking high‐utility Gibbs free energy. This innovative mechanism pioneers uncharted scientific frontiers, introducing fascinating phenomena like seismochemistry, seismochromism, and seismofluorescence that redefine the boundaries of molecular ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

The TsuJal Amphibious Seismic Network: A Passive-Source Seismic Experiment in Western Mexico [PDF]

, 2021
The geodynamic complexity in the western Mexican margin is controlled by the multiple interactions between the Rivera, Pacific, Cocos, and North American plates, as evidenced by a high seismicity rate, most of whose hypocenters are poorly located.
