Acoustic Emissions in a tectonically active area in central Italy - monitoring local and regional variations of stress
Abstract
Continuous Acoustic Emission (AE) records are being regularly collected at a site in central Italy, which was recently severely stricken by earthquakes, and which is presently experiencing the release of frequent sounds originated underground. Different kinds of analyses were carried out, including fractal properties. They revealed intriguing correlations with other geodynamic events occurring in the entire Italian area during the last two years, envisaging a large-scale correlation, in space and time, of phenomena that are generally believed to be almost independent of each other. While waiting for geochemical records to be eventually correlated with such monitoring, the present state-of-the art is presented, and possible future perspectives envisaged.
