Structural evolution of backthrusting in the Mentawai Fault Zone, offshore Sumatran forearc

Mukti_2012_g3

This article presents the interpretation of newly acquired high-quality industry-standard deep seismic reflection and swath bathymetry data to provide insight into the structural style and evolution of the Mentawai Fault Zone (MFZ). The structural style, lateral distribution and kinematics of the fault zone has been discussed related the development of forearc high thrusts and accretionary wedge mechanics. The implication of this fault zone to the coseismic rupture during slip of the megathrust is also discussed.
