Do Trench Sediments Affect Great Earthquake Occurrence in Subduction Zones?
-Seismic energy release is dominated by the underthrusting earthquakes in subduction zones, and this energy release is further concentrated in a few subduction zones. While some subduction zones are characterized by the occurrence of great earthquakes, others are relatively aseismic. This variation in maximum earthquake size between subduction zones is one of the most important features of glob...
متن کاملSubduction Zones
[1] Subduction zones are where sediments, oceanic crust, and mantle lithosphere return to and reequilibrate with Earth’s mantle. Subduction zones are interior expressions of Earth’s 55,000 km of convergent plate margins and are the geodynamic system that builds island arcs. Excess density of the mantle lithosphere in subduction zones provides most of the power needed to move the plates while in...
متن کاملExperimental Faulting of Serpentinite During Dehydration: Implications for Earthquakes, Seismic Low-Velocity Zones, and Anomalous Hypocenter Distributions in Subduction Zones
Dehydration embrittlement of serpentine was investigated by employing triaxial deformation experiments at high pressure and temperature (P = 1–6 GPa; T = 550–820oC). A modified Griggs apparatus was used up to 3.4 GPa and a Walker-type multi-anvil apparatus was used at 3.5–6 GPa). The investigated specimen is a serpentinized peridotite from Val Malenco, Italy. Dehydration of the sample under dif...
متن کاملEarthquake faulting in subduction zones: insights from fault rocks in accretionary prisms
Subduction earthquakes on plate-boundary megathrusts accommodate most of the global seismic moment release, frequently resulting in devastating damage by ground shaking and tsunamis. As many earthquakes occur in deep-sea regions, the dynamics of earthquake faulting in subduction zones is poorly understood. However, the Integrated Ocean Drilling Program (IODP) Nankai Trough Seismogenic Zone Expe...
متن کاملEvidence for active subduction at the New Guinea Trench
[1] Recent seismic tomography imaging shows clear evidence for southwestward subduction along the entire length of the New Guinea Trench (NGT) in Indonesia and Papua New Guinea. Viewed in conjunction with the occurrence of large (Mw > 7) thrust earthquakes that are known to have occurred on the trench, this confirms conclusions of earlier studies that the NGT is an active, inter-plate boundary....
