Natural hazards, events such as Earthquakes or volcanic eruptions, involve activation of coupled thermo-hydro-chemo-mechanical processes in rocks. The present book assembles the most possible unpublished contributions to the 7th Euro-conference of Rock Physics and Geomechanics, held in 2007 in Erice, Italy. Itpresents new laboratory data, theoretical and numerical rock physics models and field observations relevant to the study of natural hazards. In particular,several papers are devoted to rock failure and explore the relationship between the competing deformation micro-mechanisms. Several others investigate shear-induced anisotropy of mechanical and/or transport properties, both in large-scale geologic objects and in laboratory samples. The remaining papers treat of various aspects of rock physics and their industrial applications such geothermics and reservoir characterization. Devoted to rock physics with the purpose of application to natural hazards Reports current research in rock physics. It includes all aspects of research in this area: laboratory experiments, theoretical modelling and microstructural observations Covers an extremely broad domain, from the laboratory scale to the field, from seismology to geotechnics,and from experimental work to theory INDICE: From the contents Earthquake source: What does control earthquake ruptures and dynamic faulting?
