The instrumental and macroseismic earthquake records are generally too short and incomplete to provide a reliable judgement of past seismicity, particularly due to the long recurrence intervals of large earthquakes. Over the past decade we have witnessed a substantial progress in the characterization of active faults, in the understanding of geodynamic processes and in the development of tools for analyzing and comparing such data. This could lead to important advancements in SHA practice, which increasingly relies on geological and geophysical input, and has opened new possibilities for properly characterizing earthquake occurrence and continuum deformation. Notwithstanding, this research field is still in its immature stage, and we believe the concerned research community would benefit from a broader range of observations and from developing fault and geodynamics-based seismic hazard models.

We hope this session will gather presentations and stir discussions on a number of crucial topics, including:
• identification of seismogenic faults and characterization in terms of geometry, kinematics and slip history;
• requirements and standards in the construction of seismogenic fault repositories;
• analysis of geodynamic and kinematic data and models;
• development of on- and off-fault deformation models;
• evidence of ground shaking from past earthquakes (e.g. speleothems or precarious rocks) and their cross-checking against modeled earthquake scenarios;
• modeling of earthquake occurrence and long-term rates;
• dealing with uncertainties associated with active faulting and geodynamic data;
• requirements and tools for incorporating active faulting and geodynamic data into seismic hazard models;
• dealing with active faulting and geodynamic data; the point of view of seismic hazard practitioners.
We invite scientists from a broad spectrum of the Earth Sciences to present their results, projects or test-cases, and to contribute to the discussion with their experience and ideas.
