Near the west coast of Vancouver Island, numerous earthquakes, with a variety of focal mechanisms, occur beneath the top of the subducting oceanic crust where it dips most steeply. As the top of the ...
In the uppermost lower mantle, seismic anisotropy is ubiquitous near subducting slabs, where shear waves with horizontal polarization propagate faster than those with vertical polarization (VSH ...
The study examined the changes to the North China Craton (NCC) over 200 million years. Scientists observed subduction as well as a process known as flat-slab rollback, which is "when the subducting ...
