A study reveals that the oldest continental crust on Earth is slowly being broken up by shifting tectonic forces.

Heavily deformed plate margin. However, models of the Earth's interior constructed by scientists using seismic tomography revealed contradictory results: in the western United States, for example ...

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

It’s surprising to find remnants of a plate that we just didn’t know about at all,” Suzanna van de Lagemaat, the Utrecht University geologist whose work has reversed decades of conventional wisdom ...

Three-dimensional seismic-reflection imaging is not new. The petroleum industry has been utilizing this tool to characterize the complex geometries of the subsurface for nearly two decades.

These include subduction zones, where the great tectonic slabs covering the Earth's surface dive under one another. "Ultimately, ... a technique known as seismic tomography.

The Cascadia Subduction Zone looks a little different ... conducted an expedition at sea aboard a ship that is capable of "seismic reflection imaging," which allowed researchers to see what the ...
