Retrieval of body waves with seismic interferometry of vehicle traffic: A case study from upstate New York, USA

Seismica
Seismic interferometry of vehicle traffic recorded by a vertical seismograph array along a highway in upstate New York has recovered surface and body waves that match the velocities of waves in the Devonian and Silurian shales. Faster arrivals extracted

Interaction of Air Pressure and Groundwater as Main Cause of Sub‐Daily Relative Seismic Velocity Changes

Geophysical Research Letters, 2023
Our study investigates variations of seismic velocity that occur over short time scales of hours. We use coda wave interferometry to inspect 5 months of continuous data from a seismological array in southern Germany.

Phase noise due to vibrations in Mach-Zehnder atom interferometers

, 2006
Atom interferometers are very sensitive to accelerations and rotations. This property, which has some very interesting applications, induces a deleterious phase noise due to the seismic noise of the laboratory and this phase noise is sufficiently large ...

Monitoring Near‐Surface Changes Using Anthropogenic Seismic Vibrations

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The abundance of anthropogenic seismic noise provides a valuable resource for monitoring dynamic subsurface property changes. We utilize railway and wind turbine‐induced vibrations recorded by a geophone array to estimate surface wave attenuation and velocity in the underlying glacial deposits of Illinois.

Sub‐Wavelength Seabed Stiffness Control of Seismic Amplitude Modulation in Seafloor DAS

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Submarine distributed acoustic sensing cables record seafloor strain with striking spatial variability whose physical origin is not immediately obvious. By explicitly partitioning the recorded wavefield into ocean‐wave, Scholte‐wave, and teleseismic Rayleigh‐wave components, we show that these amplitude variations are not random but encode ...

Asteroseismic modeling of 16 Cyg A & B using the complete Kepler data set

, 2015
Asteroseismology of bright stars with well-determined properties from parallax measurements and interferometry can yield precise stellar ages and meaningful constraints on the composition. We substantiate this claim with an updated asteroseismic analysis

Distinct Crustal Structure Across the Alpine Fault, New Zealand: Seismic Imaging of a Through‐Going Vertical Fault Beneath Its Central Section

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Alpine Fault (Aotearoa New Zealand) is a major plate boundary transform fault, that quasi‐periodically hosts large (M7‐8) to great (M8+) earthquakes. The fault is thought to be segmented with sections rupturing both individually and in combination.

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.
