Analysing seismic waves and velocities including interference effects in granular matter of volcanoes — •Regine Frank1,2, Marcel van Laaten3, Birger Lühr4, and Ulrich Wegeler31College of Biomedical Sciences, Larkin University, Miami, Florida, USA — 2Donostia International Physics Center, 20018 Donostia-San Sebastian, Spain — 3Institut für angewandte Geowissenschaften, Friedrich-Schiller-Universitaet Jena — 4Deutsches GeoforschungsZentrum GFZ, Helmholtz-Zentrum Potsdam

We present self consistent diagrammatic transport theory and numerical solutions for the analysis of seismic waves and velocities including interference effects in granular matter of volcanoes. We introduce weighted essentially non-oscillatory solvers (WENO) which are suitable to treat extreme non-linear properties and rogue waves. We compare our numerical results to recent experiments and several other theoretical models.
