Structural Evolution of the Eastern Nankai Trough accretionary prism, Central Japan—Subduction of Trough-Parallel Seamount Chains

Abstract The Nankai Trough, offshore of Southwest Japan, represents a plate subduction zone where a long history of devastating mega-earthquake and tsunami events has been best documented. Because of this societal relevance, the area has been extensively studied and monitored for several decades. Among the Nankai Trough region, the Eastern Nankai Trough and the Enshu Forearc Basin remain a focal point for ongoing geological and geophysical research due to their complex morpho-structural framewor
