Recent progress on wave gradiometry method
地球与行星物理论评, 2023 Wave gradiometry method is a data processing technique based on dense seismic arrays and is suitable for a variety of seismic signals/phases such as P-waves, S-waves, Rayleigh waves, Love waves, and ambient noise.

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.

Geophysical Journal International, 1996 SUMMARY The concept of a seismic image wave is introduced and explained with the aid of some examples. Seismic reflector images in various domains (e.g. depth-migrated reflections in the depth domain or common-offset reflections in the time domain) behave like snapshots of elementary body waves.

Finite-difference modelling to evaluate seismic P-wave and shear-wave field data [PDF]
Solid Earth, 2015 High-resolution reflection seismic methods are an established non-destructive tool for engineering tasks. In the near surface, shear-wave reflection seismic measurements usually offer a higher spatial resolution in the same effective signal frequency ...

Machine Learning Seismic Wave Discrimination: Application to Earthquake Early Warning
Geophysical Research Letters, 2018 Performance of earthquake early warning systems suffers from false alerts caused by local impulsive noise from natural or anthropogenic sources. To mitigate this problem, we train a generative adversarial network (GAN) to learn the characteristics of ...

Effects of Oblique Incidence of SV Waves on Nonlinear Seismic Response of a Lined Arched Tunnel
Shock and Vibration, 2020 The incident direction of earthquake motion is an important factor affecting the seismic response of underground structures. In this study, a three-dimensional (3D) oblique incidence method of SV waves is proposed and the effects of incident angles of SV

Wavefield-reconstruction-based full waveform inversion on noisy data in seismic exploration
Frontiers in Earth ScienceFull waveform inversion (FWI) is commonly used in seismic exploration to calculate parameters of the medium, such as velocity, from the signal as it passes through the medium.
