The WP aims to characterize the seismic wavefield in the target areas by applying several methodologies to transients and background noise, in time and frequency domains.
.Activity 1. Seismic survey
A seismic array (AME), composed of 8 Short Period stations, was employed close to the Mefite D’Ansanto CO2 emission field on June 8 2021 and acquired continuous signals until Sept 28 2021.
A meteorologic station will be installed in the same area.

.Activity 2. Waveform characterization
Several methodologies are applied to seismic noise and earthquakes, in frequency and time domain: Spectral, RMS, H/V, TFA, ICA and harmonic analyses. Atmospheric patterns are matched with seismological behaviors.

Activity 3. Array techniques
Ambient noise, acquired by seismic arrays, is analyzed by using array techniques to track the wavefield components and to characterize the propagation medium.

Activity 4. Distant earthquakes
Teleseismic data are used to evaluate larger scale characteristics of propagation medium.
