A near-surface seismic scattered wave separation method
Petroleum Exploration and Development, 2014 Considering that near-surface scattered waves could not be suppressed by conventional denoise method, this paper analyzes the characteristics of scattered waves and achieves the near-surface scattered wave separation by the seismic interferometry theory.

Seismic waves increase permeability [PDF]
Nature, 2006 Earthquakes have been observed to affect hydrological systems in a variety of ways--water well levels can change dramatically, streams can become fuller and spring discharges can increase at the time of earthquakes. Distant earthquakes may even increase the permeability in faults. Most of these hydrological observations can be explained by some form of

Numerical analysis of seismic wave amplification in Nice (France) and comparisons with experiments [PDF]
, 2000 The analysis of site effects is very important since the amplification of seismic motion in some specific areas can be very strong. In this paper, the site considered is located in the centre of Nice on the French Riviera.

Tube waves, seismic waves and effective sources [PDF]
Wave Motion, 1993 The radiation of waves from a monopole source in a fluid-filled borehole into an elastic medium is considered. A simple asymptotic analysis, based on the smallness of the ratio of the borehole radius to the wavelength, reveals the interaction between tube waves and seismic waves.

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 ...

Physics‐Informed Neural Networks (PINNs) for Wave Propagation and Full Waveform Inversions [PDF]
Journal of Geophysical Research: Solid Earth, 2021 We propose a new approach to the solution of the wave propagation and full waveform inversions (FWIs) based on a recent advance in deep learning called physics‐informed neural networks (PINNs).
