This session covers the broad field of earthquake source processes, and
includes the topics of imaging the rupture kinematics and simulating
earthquake dynamics using numerical methods, to develop a deeper
understanding of earthquake source physics. We also invite presentation
that link novel laboratory experiments to earthquake dynamics, and
studies on earthquake scaling properties.

Earthquake sources are imaged using seismic data and surface deformation
measurements (e.g.GPS and InSAR) to estimate rupture properties on
faults and fault systems. Each data set and each method has its strength
and limitations in the context of the source-inversion problem, but the
uncertainties are often not well quantified and the robustness of the
source models not well known.
The session invites contributions that address the source-inversion
problem and provide new methods, innovative applications, and
thought-provoking new ideas. Contributions are welcome that make use of modern
computing paradigms and infrastructure to tackle large-scale forward
simulation of earthquake process, but also inverse modeling to retrieve
the rupture process with proper uncertainty quantification.

Earthquake source imaging, numerical modeling of rupture dynamics, and
source-scaling relations help to understand earthquake source processes.
Furthermore, new numerical modeling approaches for multi-scale
earthquake physics, including earthquake-cycle simulations, may include
fault-zone evolution and even target seismic hazard assessment. The
question that these lines of research are targeting are profound and of
first-order socio-economic relevance:

Which first-order physical processes control, at a given space-time
scale, the macroscopic evolution of dynamic rupture and its seismic
radiation? Is the physics of fault rupture the same for large and small
earthquakes? How can modern earthquake hazard assessment profit from a
deeper understanding of rupture dynamics? Which source processes need to
be considered to better understand, and then model, tsunami generation,
triggering phenomena, induced seismicity and earthquake cycles?

Within this framework our session also provides a forum to discuss case
studies of kinematic or dynamic source modeling of recent significant
