Feasibility of Using Shear Wave Ultrasonic Probes as Pump-Wave Sources in Concrete Microcrack Detection and Monitoring by Nonlinear Ultrasonic Coda Wave Interferometry [PDF]
This paper represents a first attempt to study the feasibility of using shear wave (SW) ultrasonic probes as pump-wave sources in concrete microcrack detection and monitoring by Nonlinear Ultrasonic Coda Wave Interferometry (NCWI). The premise behind our

Distant Storms Can Affect Seismic Noise Crustal Monitoring
Using seismic noise interferometry to monitor the Earth's interior relies on continuous seismic wavefields produced by stable, invariant sources. In numerous applications, this condition is relaxed, arguing that secondary scattering effects render the ...

Evaluation of ultrasonic signals collected from laboratory concrete specimens: Preprocessing and analysis with coda wave interferometryThe data used are publicly available: Diewald, F. et al.: Data for: Impact of External Mechanical Loads on Coda Waves in Concrete [Data set]. Zenodo, (2025). [PDF]
Efficient maintenance of infrastructure relies on monitoring and assessment of its condition. New technologies and methods thereby enable a deeper understanding of the materials used and of the structures built.

Earthquake‐volcano interaction imaged by coda wave interferometry [PDF]
Large earthquakes are often assumed to influence the eruptive activity of volcanoes. A major challenge to better understand the causal relationship between these phenomena is to detect and image, in detail, all induced changes, including subtle, non‐eruptive responses.

Time-Lapse Cross-Well Monitoring of CO2 Sequestration Using Coda Wave Interferometry
In this study, we explored the capability of coda wave interferometry (CWI) for monitoring CO2 storage by estimating the seismic velocity changes caused by CO2 injection. Given that the CWI method is highly efficient, the primary aim of this study was to
