Workshop 3: Seismic Interferometry: Imaging and monitoring from Near-Surface to Civil Engineering applications
Date: 29th August, 2021
Conveners: Aurélien Mordret (Univ. Grenoble Alpes), Philippe Guéguen (Univ. Eiffel), and Stéphane Garambois (Univ. Grenoble Alpes & CNRS / ISTerre / UMR 5275)
Description:
Seismic noise methods have been increasingly used for imaging and monitoring purposes of various Earth and anthropic systems since more than 10 years. Several important aspects related to the proper use of seismic interferometry will be addressed within this workshop, ranging from theoretical aspects, signal processing and sources/receiver configurations. The recent possibility to use dense seismic networks, with their interest but also the challenges posed in terms of data volume and interpretation will also be discussed.
A second part of the workshop will be dedicated to the presentation of various selected case studies, both focusing on near-surface applications (geotechnical, natural hazards, hydrology, …) and to buildings/infrastructures characterization and monitoring.
