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

Plates at subduction zones typically move just a few centimeters per year. But when accumulated stress at these convergent plate boundaries releases suddenly, the plates can slip several meters ...

Subduction zones, where lithospheric plates converge and one is forced below the other, play a critical role in plate tectonics. Unlike convergent boundaries, which push towards one another ...

The answer is subduction. In locations around the world, ocean crust subducts, or slides under, other pieces of Earth's crust. The boundary where the two plates meet is called a convergent boundary.

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

Earthquakes occur along fault lines between continental plates, where one plate is diving beneath another. Pressure builds between each plate, called fault stress. When this stress builds enough to ...

The Cascadia subduction zone, where the oceanic Juan de Fuca plate descends beneath ... Figure 4: Schematic cross-section of the northern Cascadia convergent margin at southern Vancouver Island. The ...

In regions of convergence, one plate can sink under another in a subduction zone, or two colliding plates can form a mountain belt. At divergent boundaries, plates move away from each other and ...

The Pacific Northwest is at risk for a mega-earthquake because of the Cascadia Subduction Zone. The region is primed for powerful quakes, with a particularly strong one called the Big One ...

When plates come together at convergent boundaries, they often slide under each ... The biggest earthquakes happen at "subduction zones," the points where one tectonic plate slides under another. Big ...
