This paper presents a versatile model-free approach for linking the damage in highly heterogeneous materials at multiple scales. The proposed scheme evolves from phase-field modelling microscopic scale to simulate brittle failure, towards estimation of effective elastic, toughness and strength properties material mesoscopic scale, via coarse-graining technique. On one side, it’s shown that, com...

[1] Volcanoes generate a variety of pre-eruptive lowfrequency seismic signals. Hybrid earthquakes comprise a class of these signals having high-frequency onsets followed by low-frequency ringing. They are used empirically to predict eruptions, but their ambiguous physical origin limits their diagnostic use. The short-duration, near-field hybrid seismograms associated with the 2004 Mount St. Hel...

The paper deals with the suitability of using the morphostructural analysis of the digital relief model (DRM) for compiling a geological map fault network focused on brittle failure of the rock mass. Attention is paid to the description of the procedure of interpreting the individual outputs of the morphometric methods selected. An important role in compiling the resulting network of the rock m...
