Seismic Velocity of Chlorite Under High Pressure and Temperature and Implications for the Lesser Antilles Subduction Zone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Chlorite is thought to be one of the major water‐carrying phases in subduction zones, both within the slab and in the mantle wedge. Its presence has previously been linked to common seismological observations at subduction zones, including P and S wave anisotropy as well as high VP/VS ratios (>1.8) in the mantle wedge.

Source Effects in Higher‐Order Ambient Seismic Field Correlations

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Ambient seismic noise interferometry is widely used for surface wave imaging. It typically requires synchronous station recordings and assumes uniform noise source distributions. Higher‐order correlations, such as the re‐correlation of the reconstructed direct waves C2 $\left({C}_{2}\right)$, enable imaging with asynchronous data and can ...

Time reversal and plane-wave decomposition in seismic interferometry, inversion and imaging [PDF]

, 2013
textThis thesis concerns the study of time reversal and plane-wave decomposition in various geophysical applications. Time reversal is a key step in seismic interferometry, reverse time migration and full waveform inversion.

Numerical simulation of wave propagation in 2-D fractured media : scattering attenuation at different stages of the growth of a fracture population [PDF]

, 2007
In this paper, we systematically examine the multiple scattering process of seismic waves at consecutive stages of the evolution of 2-D fracture population. Synthetic seismograms are computed using the pseudo-spectral method for elastic wave propagation,

Temporal Changes of Seismic Velocity Caused by Volcanic Activity at Mt. Etna Revealed by the Autocorrelation of Ambient Seismic Noise

Frontiers in Earth Science, 2019
On active volcanoes, ambient noise-based seismic interferometry can be a very useful monitoring tool as it allows to detect very slight variations in seismic velocity associated with magma transported toward the surface.

The Spatiotemporal Evolution of Creep on the Southern San Andreas Fault Between 2015–2021

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Southern San Andreas fault (SSAF) in the Coachella Valley experiences shallow creep and slow slip events (SSE), which re‐distribute stresses in the seismogenic zone and affect the potential of future earthquakes. Although average creep rates are relatively well‐constrained, untangling the details of spatiotemporal variation in creep along ...

Evaluating Seismic Ambient Noise Techniques for Detecting Ice‐Bearing Rocks on the Moon

Earth and Space Science
One of the primary objectives of upcoming lunar missions is to locate ice‐bearing rocks at the South Pole. While evidence for their presence exists, the exact distribution and quantity remain uncertain. In this study, we evaluate the potential of seismic

The application of seismic interferometry for estimating a 1D S-wave velocity model with the use of mining induced seismicity

Journal of Sustainable Mining, 2018
The main objective of this paper is to present the usefulness of the seismic interferometry method to determine the S-wave velocity model of the rock mass affected by exploitation in the KGHM Rudna copper ore mine.

Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, Volume 33, Issue 5, Page 1255-1268, September 2026.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...
