For the first time, scientists have seen a subduction zone actively breaking apart beneath the Pacific Northwest. Seismic data show the oceanic plate tearing into fragments, forming microplates in a ...

A subduction zone near Cascadia is unraveling piece by piece. The process offers a rare glimpse into how tectonic plates die ...

Several billion-year-old rocks tell the story of the planet’s transition from alien landscape to one of continents, oceans, and ultimately life A new study from scientists at Scripps Institution of ...

Geoscientists have discovered a new process in plate tectonics which shows that tremendous damage occurs to areas of Earth's crust long before it should be geologically altered by known plate-boundary ...

In some parts of Earth's interior, seismic waves travel at different speeds depending on the direction in which they are ...

(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 ...

A new analysis suggests that massive earthquakes on northern sections of the Cascadia Subduction Zone, affecting areas of the Pacific Northwest that are more heavily populated, are somewhat more ...

Around 800 million years ago, during the Tonian period, the Yangtze Block in South China experienced significant tectonic activity, in which the ancient supercontinent Rodinia broke off from the area ...

TORONTO, ON - Geoscientists at the University of Toronto (U of T) and Istanbul Technical University have discovered a new process in plate tectonics which shows that tremendous damage occurs to areas ...
