It was a groundbreaking discovery. Scientists have found previously concealed fault lines along California’s north coast, ...

By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San Andreas fault meets the Cascadia subduction zone, an area that could give rise ...

Seismic tremors reveal a shallow fragment of ancient tectonic plate beneath Northern California, helping explain damaging ...

Sometimes to truly study something up close, you have to take a step back. That's what Andrea Donnellan does. An expert in Earth sciences and seismology, she gets much of her data from a bird's-eye ...

The King's Trough Complex is a several-hundred-kilometer-long, canyon-like system of trenches on the North Atlantic seafloor.

The modern understanding of the plate tectonic cycle predicts that remnants of submerged plates will be found near subduction zones. However, a new high-resolution model shows that these remnants can ...

Scientists uncover hidden faults beneath Northern California’s Mendocino triple junction. The discovery reshapes ...

The Cascadia subduction zone is more complex than researchers previously knew. The new finding could help scientists better understand the risk from future earthquakes. When you purchase through links ...

Rocks once buried deep in ancient subduction zones -- where tectonic plates collide -- could help scientists make better predictions of how these zones behave during the years between major ...

A hidden chunk of an ancient tectonic plate is stuck to the Pacific Ocean floor and sliding under North America, complicating earthquake risk at the Cascadia subduction zone. When you purchase through ...

Hell, or something like it, may be a little closer than we thought. As a new study published in Nature Geoscience reveals, geologists at Cornell and the University of Texas have discovered a “hidden” ...

Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. Researchers had previously identified ...
