Jessica DePaolis (second from left) and the team of researchers studied and compared sedimentary core samples in Montague Island, Alaska, and found evidence that four of the past eight earthquakes ...

(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 ...

EUGENE, Ore. (NBC) -- When an earthquake rips along the Cascadia Subduction Zone fault, much of the U.S. West Coast could shake violently for five minutes, and tsunami waves as tall as 100 feet could ...

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 ...

The vast stretch of ocean between the Americas and Europe may be about to close soon—on a geological timescale. Just before the continents begin to drift back together, an "Atlantic ring of fire" is ...

A modeling study suggests a slumbering subduction zone below the Gibraltar Strait is active and could break into the Atlantic Ocean in 20 million years' time, giving birth to an Atlantic "Ring of Fire ...

The Earth's lithosphere is the rigid outer shell of the planet and is broken into several tectonic plates. These plates are in constant motion over the semi-fluid asthenosphere underneath them. Much ...

South of New Zealand in the Tasman Sea is a stretch of stormy ocean where the waves regularly swell 20 feet (6 meters) or more and the winds blow at 30 mph (48 km/h) on a good day. Deep below these ...

Groundbreaking research has provided new insight into the tectonic plate shifts that create some of the Earth's largest earthquakes and tsunamis. Groundbreaking research has provided new insight into ...
