Query: Rough Subducting Seafloor Reduces Interseismic Coupling and
  Mega-Earthquake Occurrence: Insights From Analogue Models   The roughness of the subduction interface is thought to influence seismogenic
behavior in subduction zones, but a detailed understanding of how such
roughness affects the state of stress along the subduction megathrust is still
debated. Here, we use seismotectonic analogue models to investigate the effect
of subduction interface roughness on seismicity in subduction zones. We
compared analogue earthquake source parameters and slip distributions for two
roughness endmembers. Models characterized by a very rough interface have lower
interface frictional strength and lower interseismic coupling than models with
a smooth interface. Overall, ruptures in the rough models have smaller rupture
area, duration and mean displacement. Individual slip distributions indicate a
segmentation of the subduction interface by the rough geometry. We propose that
flexure of the overriding plate is one of the mechanisms that contribute to the
heterogeneous strength distribution, responsible for the observed seismic
behavior.
