WHISPER · Towards continuous monitoring of the continuously changing Earth

This project is focused on the use of the seismic ambient noise to monitor slight changes of properties in the solid Earth. Processing of noise records allow s to mimic a situation in which a perfectly repeatable source is activated at the location of a passive recorder. The implication is the detection of changes of strain at depth with applications in different contexts. A major field of application is the monitoring of potentially dangerous structures like volcanoes or active fault zones prone to damaging earthquakes. The project includes new methodological developments and field experiments. Applications in regions where changes are induced by human activity are important both for the quantitative refinement of the method and for the important economic and social implications of these problems.
