This study, published in Earth and Planetary Physics, explores the subduction thermal state, slab metamorphism, and seismic ...

Otherwise, plate dowels can break out of the concrete from the top or bottom of the slab. By allowing slab movements perpendicular to the joint, doweled construction joints can act like ...

A breakthrough study has provided the most detailed 3D look yet at the inner workings of the Tonga Subduction Zone, where ...

Q: I’m planning to install vinyl siding on a detached garage that’s built on a concrete slab. The siding instructions suggest ...

By contrast, geophysical observations, in particular from seismology, indicate that some subducted oceanic plates, known as slabs, sink all the way into the lower mantle (Fig. 1). This seems to ...

Deep beneath Earth’s surface, researchers have discovered an ancient seafloor buried for millions of years. This unexpected ...

One explanation for plate movements is slab pull. Plates are extremely heavy so gravity acts upon them, pulling them apart. Alternatively, as shown in the diagram, convection currents under the ...

evidence suggests it is the plates that drive the convection. Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones. As these older sections of plates sink ...

High-Resolution Anisotropic Tomography Reveals Mantle Flow Complexity and Slab-Plume Interactions, Redefining Subduction Zone ...
