Source separation has not been fully addressed by geophysicists and is a crucial first step to locating simultaneous sources, which in turn helps with understanding the dynamics of the sources and their source mechanisms. DUET is applied to synthetic seismic signals. The source separation method works successfully to separate two contemporary explosive sources, and two simultaneous oblique tensile cracks in a 3D structural model of Mt Etna. The method is also applied to field recordings on Mt Etna from 2008. The method separates Long Period events from tremor, Long Period events from Volcano Tectonic events and different sources of tremor from each other.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||Institute of Electrical and Electronic Engineers||Journal:||IEEE Signal Processing Magazine||Volume:||29||Issue:||3||Start page:||16||End page:||28||Copyright (published version):||2012 IEEE||Keywords:||Source separation; Geophysical signal Processing||Subject LCSH:||Source separation (Signal processing)
