They found that slab geometry can greatly influence the pressure and behavior of mantle convection. For instance, subduction zones with wide, long, and thick slabs—like the Kuril-Japan-Izu-Bonin ...

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 a subducting slab, olivine can delay its transition into other mineral states under high temperature and pressure "This delayed transformation may generate stress and release energy ...

"Geodynamic simulations have attributed the geometry and stability of the lower mantle structures to their direct interactions with subducting slab," the team write in their paper. The researchers ...
