We look forward to receiving your abstracts and seeing you in Vienna.
Best Regards,

************ Session Description ************
Geophysical studies of recent well-monitored mega-earthquakes are
revealing with an increasing resolution the complex mechanical
heterogeneities along faults (differential locking behavior,
differential rupture behavior, rheological and structural variations,
among others). Furthermore, observations of various transient events
(after slips, slow slips, tectonic tremors, LFEs) also evidence the
temporal evolutional nature of fault systems. While fault
heterogeneities seem to have first order controls on the pattern of
strain accumulation/release and carry fundamental information about the
mechanical setting of faults, we have limited physical and mechanical
understanding of what causes these heterogeneities, their kinematics and
transient evolution between major events, and how they ultimately
influence the largest seismic events. We aim to integrate studies from
various disciplines in order to compare different observations and
provide insights into the physical and transient properties of fault
heterogeneities and their relation to earthquakes. Contributions from
geologists, seismologists, geodesists, experimentalists, and modelers
are invited.
Some suggested topics are:
* Roughness/asperities/geometry of faults
* Geodetic records of fault slip in different periods of the earthquake cycle
* Co-seismic slip inferred from seismic records of various frequencies
* Spatiotemporal variation of seismicity and transient events, seismic vs. aseismic slip
* Seismic and electromagnetic attributes around faults from tomography
* Relation between fault heterogeneity and rock physical/rheological properties
* Numerical modeling of fault zone kinematics
