A megathrust earthquake is coming for the Pacific Northwest. But new imaging of undersea faults and fractures has given ...

(a) Geological units and earthquake distribution of an oceanic subduction zone. The orange shadow beneath the volcanic arc represents partially molten areas and magma channels. (b) Thermal structure ...

Scientists warn that the plate beneath Gibraltar arc will begin to shift toward the Atlantic within 20 million years.

The Cascadia Subduction Zone is unusually quiet for a megathrust fault. Spanning more than 600 miles from Canada to California, the fault marks the convergence of the Juan de Fuca and North American ...

For decades, the end-stage life of a subduction zone existed only in theory. Now, for the first time in geologic history, scientists are bearing witness to the Juan de Fuca Plate tearing apart and ...

Our planet's lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in ...

The SZ4D Implementation Plan details how the scientific community plans to make major advances in understanding subduction zone hazards. Subduction zones, where one tectonic plate slides beneath ...

A new study from scientists at Scripps Institution of Oceanography at UC San Diego and the University of Chicago sheds light on a hotly contested debate in Earth sciences: when did plate subduction ...

Scientists have uncovered one of the most exciting geological discoveries of the decade – the long-lost Pontus tectonic plate. This ancient “mega plate,” which once spanned an astonishing 15 million ...

Subduction zones, where one tectonic plate slides beneath another, produce the most devastating seismic, volcanic, and landslide hazards on the planet. A new report presents an ambitious plan to make ...
