Waveform Inversion of Passive Seismic Data Using Multi-Scattered Energy
, 2018 Locating micro-seismic events highly relies on the velocity accuracy. Full waveform inversion (FWI) has the potential to invert velocity and micro-seismic source image simultaneously.

Deep Underground Science and Engineering, EarlyView.This study investigates the damage evolution and failure mechanisms of tunnel lining concrete in active fault zones through uniaxial compression tests integrated with acoustic emission (AE) monitoring. A strong linear correlation is identified between the AE cumulative absolute energy and the total strain energy, providing a reliable energy‐based ...

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.

Energy ratio of reflected and refracted seismic waves* [PDF]
Bulletin of the Seismological Society of America, 1944 IV. Summary The investigation of amplitudes of elastic waves passing through layers of the earth, either in earthquakes or from artificial explosions, requires a knowledge of the distribution of energy at points of reflection or refraction, and also of the ratio between the amplitudes arriving at the surface of the earth and the ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been
