Dear all,

We invite you to consider submitting an abstract to this 
multidisciplinary session to be held at the EGU General Assembly 2018 in 

*TS5.3/GD5.4/NH4.10/SM 2.17*

*Accommodating crustal deformation along subduction terminations: from 
co-seismic slip to million-year deformation patterns*

Convener: Vasiliki Mouslopoulou, Co-Conveners: Onno Oncken, Andy Nicol, 
Stathis Stiros, Bernd Schurr

Active subduction margins terminate against, and transfer their slip 
onto, plate-boundary transform faults. The manner in which plate motion 
is accommodated and partitioned across such kinematic transitions from 
thrust to strike-slip faulting over earthquake timescales, is poorly 
documented. The 2016 November 14th, Mw 7.8 Kaikoura Earthquake provides 
a rare snapshot of how seismic-slip may be accommodated at the tip of an 
active subduction margin. This earthquake also poses the question 
whether such multi-fault, multi-mechanism, ruptures are typical for 
subduction terminations and how do they reconcile with long-term 
deformation patterns across such kinematic boundaries.

This session aims to bring together seismologists, geodesists, numerical 
and analogue modellers, paleoseismologists and structural geologists to 
shed light on the deformation processes that govern subduction 
terminations over a range of timescales: from individual large-magnitude 
historic/prehistoric earthquakes to the million-year structural 
evolution of subduction-thrust terminations. We hope that this session 
will provide the basis for an in-depth discussion, using case studies 
from subduction systems globally, which will help to better characterise 
the deformation mechanisms and associated seismic hazard at the tips of 
active subduction margins.

Participation of early career geoscientists is encouraged.

*Looking forward to receiving your abstracts and discussing your ideas!*
