Abstract

Long-Period (LP) volcanic earthquakes are characterized by a relatively long duration codas and spectra containing pronounced spectral peaks. These peculiar spectral characteristics are often attributed to source effects, such as resonances of fluid-filled cracks. In this paper, we report the results of numerical simulations of seismic wave propagation showing that the main signal features of the LP earthquakes (long duration and spectral peaks) can arise from strong multiple scattering in the strogly heterogeneous volcanic media.
We consider seismic sources located within a strongly heterogeneous volcanic plumbing system created through m...  more
