| Session Description | The goal of this session is to investigate the dynamic behaviour of mobile belts from the rheology to the geology with laboratory, modelling, and geological perspectives. We work towards the reconciliation of short-time/small-scale and long-time/large-scale observations, to gain a physical understanding of mobile belts and the devastating impact seismic events can have on society. Despite the remarkable advances in experimental rock-mechanics, the implications of rock-mechanics data for large temporal and spatial scale tectonic processes are still not straightforward, since the latter are strongly controlled by local and regional conditions such as lithology and rheological stratification of the lithosphere, its thermal structure, fluid content, tectonic heritage, metamorphic reactions and deformation rates. To gain a physical understanding of the dynamics of mobile belts, an integration of geophysics, geomorphology, petrology, geochemistry and geology is necessary, as is the integration of observational, theoretical and experimental approaches. We therefore invite researchers from different domains (geophysical modellers, rock mechanics, structural geology, geodynamic and small-scale thermo-mechanical modelling, tectonics, geodesy and geophysics, as well as interdisciplinary studies) to address issues relating to the dynamic behaviour of mobile belts. This includes such issues as pre-, co-, and post-seismic processes, the rheology of seismogenic faults and fault rocks, laboratory experiments on elementary processes, numerical models based on frictional laws and ductile deformation, and estimates of the stress field in the seismogenic zones. We also welcome studies on fault-zone drilling projects and in situ stress measurements. We particularly welcome contributions covering recent fault ruptures, including the Central Mexico, Kaikoura (New Zealand), Amatrice (Italy), and Kumamoto (Japan) earthquakes. |
