T79. Multidisciplinary approaches to the geometric and kinematic definition of seismogenic faults

Geological structures capable of generating significant earthquakes release elastic stress accumulated during the interseismic phases at depths of 10-15 km into the upper crust.
While the surface effects of higher magnitude earthquakes can be recognized and studied through well-established techniques at the surface, the portion of the faults where the ruptures nucleate can only be investigated through indirect observations that include reflection and refraction geophysical prospecting, tomographic analysis at various scales, and other geophysical methods (e.g. gravimetry, magnetometry).
The processes that lead to the formation or reactivation of faults in the upper crust can also be investigated through numerical and/or analogue modelling, that provide insights into the geomechanical processes that drive deep fault structuring.
The session aims to gather contributions integrating different methodologies aimed at the geometric and kinematic description of seismogenic and potentially seismogenic faults from the topographic surface to the base of the seismogenic layer.
We encourage contributions that explore the geometric and kinematic characteristics and variability of tectonic structures at the surface and subsurface through active and passive geophysical methods, analogue and numerical modelling, and structural-geological field analysis, as well as through the integration of these. Contributions from doctoral students and young researchers will be especially welcome.
