Decomposition of high-frequency seismic wavefield of the Strombolian-like explosions at Erebus volcano by Independent Component Analysis.
The characteristics of the Strombolian-like activity at Erebus volcano (Antarctica) are evidenced by decomposing the wavefield of the explosion-quakes associated with the bursting of gas slugs at the surface. The decomposition is achieved by adopting a non-linear technique operating in time domain,...
