Brown, K. M., Bangs, Nathan Lawrence Bailey, Froelich, Peter N., Zheng, Y., Didyk, Borys M., Prior, D., Rochford, E. L., Torres, Marta E., Kurnosov, V. B., Lindsley - Griffin, N., Osozawa, S., and Waseda, A.

Abstract:

The subduction of the oceanic spreading center at the Chile Triple Junction is marked by a substantial thermal perturbation and marked changes in the hydrogeologic and aqueous geochemical regimes in the overthrust plate. Ridge subduction substantially changes the fluid chemistry in the wedge through variably hydrating the oceanic basement, accretionary...

Abstract:

The two largest earthquakes ever recorded, the 1964 M[subscript w] 9.2 Alaskan and 1960 M[subscript w] 9.5 Chilean, occurred on seismogenic plate interfaces at subduction zones. It has been theorized that the catastrophic failure of a locked zone along the contact between the downgoing slab and the upper plate causes...
