Structural damage detection using Bayesian inference and seismic interferometry

Structural Control & Health Monitoring, 2019
We present a computational methodology for structural identification and damage detection via linking the concepts of seismic interferometry and Bayesian inference. A deconvolution‐based seismic interferometry approach is employed to obtain the waveforms

On the Construction of Moho Reflected Shear Wave Phases From Ambient Noise

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Shear waves reflected from the Moho (SmS) are frequently identified in ambient noise cross‐correlation functions. Despite their consistent appearance across various arrays and studies, the physical origin and generation mechanisms of these SmS phases remain poorly understood.

Co‐Seismic Deformation and Local Stress Evolution of the Philippines Earthquakes in July and October 2022 Revealed by InSAR and GNSS Observations

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract On 27 July and 25 October 2022, an Mw 7.0 earthquake and an Mw 6.4 earthquake struck Abra, northwest of Luzon, Philippines, respectively, with a time interval of less than 3 months and a distance of about 16 km. In this research, interferometric synthetic aperture radar (InSAR) was utilized to retrieve the co‐seismic surface deformation field ...

Passive seismic interferometry by multidimensional deconvolution

GEOPHYSICS, 2008
We introduce seismic interferometry of passive data by multidimensional deconvolution (MDD) as an alternative to the crosscorrelation method. Interferometry by MDD has the potential to correct for the effects of source irregularity, assuming the first arrival can be separated from the full response.

Matter-wave laser Interferometric Gravitation Antenna (MIGA): New perspectives for fundamental physics and geosciences

, 2014
The MIGA project aims at demonstrating precision measurements of gravity with cold atom sensors in a large scale instrument and at studying the associated applications in geosciences and fundamental physics.

Back‐Propagating Earthquakes on Simple Faults

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Back‐propagating earthquakes, characterized by a secondary front reversing into previously ruptured areas, challenge conventional models of rupture dynamics and have been increasingly documented in recent years. The conditions for this phenomenon remain poorly understood: while rupture complexity is often attributed to fault heterogeneity ...

Turning standalone seismometers into strainmeters using tidal strain and ambient noise: a feasibility study

Earth, Planets and Space
Solid Earth is subjected to gravitational tidal deformations in the nanostrain order. We focus on detecting seismic shear wave velocity changes caused by this phenomenon.

Metastable Olivine Wedge Beneath the Japan Sea Imaged by Seismic Interferometry

Geophysical Research Letters, 2019
The metastable olivine wedge (MOW) within subducted slabs has long been hypothesized to host deep‐focus earthquakes (>300 km). Its presence would also rule out hydrous slabs being subducted into the mantle transition zone.

Implications of very long baseline interferometry measurements on North American intra-plate crustal deformation [PDF]

Very Long Baseline Interferometry experiments over the last 1-3/4 years between Owens Valley, CA and Haystack, MA Radio Observatories suggest an upper limit of east-west crustal deformation between the two sites of about 1 cm/yr. In view of the fact that
