Viability of Coda Wave Interferometry for Fatigue Monitoring of Asphalt Mixtures

, 2023
Abstract For asset management, various non-destructive techniques are used to assess the structural or functional integrity of the pavements to help determine the correct maintenance and rehabilitation (M&R) treatments to prolong the useful service life of a pavement.

Tracking Subsurface Changes via Frequency Shifts in Volcanic Tremor Spectral Lines: Observations From Mt Etna

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Episodes of volcanic tremor provide valuable insights into the dynamics of subsurface processes at active volcanoes. Previous studies have suggested that evolving tremor properties may relate to changes in the stress conditions of the plumbing system. However, a strong causative link has remained elusive.

Supershear Transitions and Bilateral Asymmetric Rupture of the 2025 Sagaing (Myanmar) Earthquake Revealed by Geodetic and Seismic Observations

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Sagaing Fault (SF) accommodates major plate motion in Myanmar, yet large earthquakes along it have rarely been captured by modern geodetic and seismic observations. The 2025 Sagaing earthquake generated an exceptionally long rupture (∼535 km), offering a rare opportunity to investigate rupture dynamics along continental transform fault. We

A Decadal Survey of the Near‐Surface Seismic Velocity Response to Hydrological Variations in Utah, United States

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Ongoing climate change is leading to an increase in prolonged droughts and severe weather events, which are particularly pronounced in semi‐arid regions, such as the western United States. These extremes could have lasting social and environmental impacts.

Direct Modeling of the Mechanical Strain Influence on Coda Wave Interferometry

Journal of Geophysical Research: Solid Earth, 2018
AbstractCoda waves interferometry (CWI) aims at tracking small changes in solid materials like rocks where elastic waves are diffusing and so intensively sampling the medium, making the technique more sensitive than those relying on direct wave arrivals.

Research on damage and stress monitoring analysis of cement-based materials based on integrated sensing element (ISE)

Case Studies in Construction Materials
Embedded sensors can achieve long-term on-site monitoring due to their stable position and good integration with the host medium. At present, there are few studies on the stress monitoring performance of integrated sensing element (ISE) applied to cement-

Absence of Detectable Precursory Deformation and Velocity Variation Before the Large Dome Collapse of July 2015 at Volcán de Colima, Mexico

Frontiers in Earth Science, 2018
Improving the ability to foresee volcanic eruption is one of the main objectives of volcanologists. For this purpose, it is essential to better detect eruption forerunners and to understand their relationship with eruptive processes.

Internal stress determination in a polymer composite by Coda wave interferometry

IOP Conference Series: Materials Science and Engineering, 2016
Coda wave interferometry (CWI) is largely employed in geotechnical applications to monitor changes due to cracks in materials but it is still not used for composite materials. In this paper, the technique is proposed to study internal stresses in a composite laminate [0°/90°]63 and was compared with the traditional acoustic technique.
