T80. Unveiling earthquake mechanics, from field to laboratory based approach

-

Congressi SGI-SIMP

Earthquake mechanics is controlled by processes active over a wide range of scales, from kilometres to nanometres and from seconds to thousands of years. The 3-D structure of fault systems and the thermo-hydro-mechanical properties of fault rocks affect the nucleation, propagation and arrest of seismic ruptures, which can locally reach the topographic surface. Nevertheless, our comprehension of earthquake mechanics remains limited due to the impossibility to access seismogenic faults at hypocentral depths.
Consequently, unravelling the wide and complex spectrum of processes governing earthquake mechanics and the seismic cycle along fault zones, requires a multidisciplinary and multiscale approach including field-based investigations, micro-analytical techniques, rock-deformation experiments and numerical modelling.
In this session, we welcome contributions dealing with the different aspects of earthquake mechanics, such as (but not limited to):
  • Quantification of the 3-D fault structure through structural and geophysical investigations;
  • Investigations of the on- and off-fault deformation processes through microstructural and geochemical analysis of natural and experimental fault rocks;
  • Evolution of the mechanical, frictional and transport properties of faults from field to laboratory scale;
  • Modelling of seismic sequences considering long-term evolution of realistic fault networks.

CONVENERS: Simone Masoch (Università di Padova), Rocco Novellino (INGV), Giovanni Toffol (Università di Padova), Mattia Pizzati (Università di Parma), Barbara Marchesini (Sapienza Università di Roma), Stefano Aretusini (INGV)
