Using Repeating Microearthquakes to Infer Medium Velocity Variations at Val d’Agri Area (Southern Italy)

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
We investigated the correlation between water level of Pertusillo artificial lake and both earthquake production and medium velocity changes in the Val d’Agri area (Southern Italy) estimated by Coda Wave Interferometry (CWI) applied to repeating ...

Seismic Velocity Variations Observed Prior to the La Palma Volcano Eruption on 19 September 2021, in Cumbre Vieja, Canary Islands (Spain)

The Seismic Record
In the recent years, coda-wave interferometry from seismic noise correlation functions has been increasingly used for volcanic eruption forecasting through velocity changes observed in the crust.

Active-Passive Monitoring of Concrete under Uniaxial Pressure: Relating Acoustic Emission and Ultrasonic Velocity for Elastic Property Assessment

e-Journal of Nondestructive Testing
Concrete is the most commonly used building material in the world – therefore to ensure the durability, safety, and long-term serviceability of concrete structures, quantitative non-destructive monitoring and testing techniques are crucial. However, the
