We investigated the deformation in the accretionary wedge associated with subducted seamounts in the northern Manila Trench by combining observations from seismic profiles and results from laboratory sandbox experiments. From three seismic reflection profiles oriented approximately perpendicular to the trench, we observed apparent variations in structural deformation along the trench. A number of back-thrust faults were formed in the accretionary wedge where subducted seamounts were identified… 
Effects of trench‐perpendicular ridge subduction on accretionary wedge deformation: Clues from analogue modelling
Basement highs (e.g., seamounts and ridges) often exist on subducted oceanic plates. However, their effects on the deformation of accretionary wedges have not been well understood, in particular the
Forced Subduction Initiation at Passive Continental Margins: Velocity‐Driven Versus Stress‐Driven
Subduction initiation (SI) at passive continental margin plays a key role in the Wilson cycle of plate tectonics; however, the long‐lived, stable Atlantic‐type margin challenges this hypothesis. The
Formation of Hengchun Accretionary Prism Turbidites and Implications for Deep‐water Transport Processes in the Northern South China Sea
Located at the end of the northern Manila Trench, the Hengchun Peninsula is the latest exposed part of Taiwan Island, and preserves a complete sequence of accretionary deep‐sea turbidite sandstones.
Geochemical and Geochronological Constraints on the Origin and Emplacement of the East Taiwan Ophiolite
The East Taiwan Ophiolite (ETO) occurs as blocks and thrust sheets associated with the Lichi Mélange in the Coastal Range of eastern Taiwan. The blocks consist of serpentinized harzburgite,
Cartographic Interpretation of the Seafloor Geomorphology Using GMT: a Case Study of the Manila Trench, South China
The study is geographically focused on the Manila Trench, located in the west Pacific Ocean, South China Sea, west Philippines. The research aims at the geological mapping, analysis and visualizing


Deformation of accretionary wedges in response to seamount subduction: Insights from sandbox experiments
Sandbox experiments, using a two‐dimensional and a three‐dimensional approach, are used to study the deformation of margins in response to seamount subduction. Successive mechanisms of deformation
Sediment accretion against a buttress beneath the Peruvian continental margin at 12° S as simulated with sandbox modeling
Reflection seismic data from the Peruvian continental margin at 12° S clearly reveal an accretionary wedge and buttress. Sandbox experiments applying the physical concept of the Coulomb theory allow
Tectonics and hydrogeology of the northern Barbados Ridge: Results from Ocean Drilling Program Leg 110
Drilling near the deformation front of the northern Barbados Ridge cored an accretionary prism consisting of imbricately thrusted Neogene hemipelagic sediments detached from little-deformed Oligocene
Effects of subducted seamounts on megathrust earthquake nucleation and rupture propagation
Subducted seamounts have been linked to interplate earthquakes, but their specific effects on earthquake mechanism remain controversial. A key question is under what conditions a subducted seamount
Subduction erosion along the Middle America convergent margin
From seismic images, erosion by seamount tunnelling and removal of large rock lenses of a distending upper plate are identified, indicating that erosion may extend along much of the Middle America convergent margin.
Transition from oblique subduction to collision in the northern Luzon arc-Taiwan region: Constraints from bathymetry and seismic observations
We systematically study the detailed bathymetry, seismicity, and source parameters of large- and moderate-sized earthquakes that occurred in the northern Luzon arc-Taiwan region between 1964 and
Trans-Alaska Crustal Transect and continental evolution involving subduction underplating and synchronous foreland thrusting
We investigate the crustal structure and tectonic evolution of the North American continent in Alaska, where the continent has grown through magmatism, accretion, and tectonic under-plating. In the
