Hidden Roughness of Subducting Seafloor and Implications for Megathrust Seismogenesis: Example From Northern Manila Trench

Abstract A smooth subducting seafloor usually leads to a smooth megathrust, which promotes great earthquakes. We present a case study at the northern Manila Trench to emphasize that the process depends also on sediment accretion and deformation. Here, a very rugged igneous basement is hidden beneath...
