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 view,

Focusing on an area off the coast of Crescent City, California, the researchers used autonomous and remotely operated vehicles to get detailed views of the slope and sediment deposits. They also used sediment cores from the region to radiocarbon-date the turbidite deposits and compare their timing to the dates of known ancient Cascadia quakes.

Earthquakes happen daily, sometimes with devastating consequences, yet predicting them remains out of reach. What scientists can do is map the hidden layers beneath the surface that control how strongly the ground shakes.

Hundreds of earthquakes have been detected rattling Antarctica's Thwaites Glacier, also known as the Doomsday Glacier.

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.

Climate journalist Emma Pattee has been worried about the so-called big one—an off-the-charts earthquake—hitting her town in Portland, Ore., for some time now. She’s not alone: scientists estimate at least a 37 percent likelihood that such a temblor ...

Deep beneath the surface, our planet is a reactor, and one of the ways you'll feel this activity is when there's an earthquake. Earthquakes are violent shaking from the planet's surface, according to AccuWeather. They're caused by movement from Earth's ...
