Independent component analysis as a monitoring tool in geophysical environment: The case of Campi Flegrei (Italy)

摘要

This work presents specific applications of techniques based on the Independent Component Analysis to the seismicity recorded at Campi Flegrei caldera. We show the capability of that technique in discriminating different kinds of signals and extracting high-quality waveforms from a noisy background. The approach is suitable for real time implementation in monitoring practice. Moreover, the results provided by these methodologies can be used to improve the knowledge of the volcano dynamics.
