Aseismic zone and earthquake segmentation associated with a deep subducted seamount in Sumatra

Abstract:

The subduction of large topographic features such as seamounts has been linked to plate locking1-7, earthquake generation8 and segmentation6, as well as crustal erosion9,11 at subduction zones. However, the role of subducted features in the generation of megathrust earthquakes has been difficult to discern because traditional imaging techniques are limited to the upper 12 km of the Earth's crust12, whereas these ruptures initiate at depths of 20-40 km (ref. 13). Here we use a deeply penetrati...
