A massive underwater volcano known as Axial Seamount could erupt soon, completely reshaping the floor of the Pacific Ocean.

This volcanic arc delineates the boundary between the Pacific and North American tectonic plates. A subduction zone, composed of the deep Aleutian Trench coupled with a landward line of volcanoes ...

This 2022 satellite photo shows the summit of "one of the world's most dangerous volcanoes," Mount Vesuvius, peering up ...

Earth bubbles and broils beneath an underwater peak called Axial Seamount, located 480 kilometers (300 miles) off Oregon's ...

These ancient buried "super-continents"—known to scientists as large low-seismic-velocity provinces (LLSVPs)—were found ...

The underwater volcano Axial Seamount is on the brink of eruption, and scientists warn that this event is inevitable. Located ...

Here we explain how and why the crisis developed. Iceland is a country of fire and ice, home to several volcanoes and straddling two tectonic plates. The Eyjafjallajokull volcano began erupting in ...

NASA has released images of a vanishing "ghost island" in the Caspian Sea captured by its satellites. The Kumani Bank mud ...

Layers of lava build up over time, creating volcanoes. Tectonic plates are key. They are large pieces of the Earth’s crust which can move towards, away from, or alongside one another ...

Axial Seamount, one of the most active volcanoes in the Pacific, is showing clear signs of an impending eruption.

This volcano is the highlight of a chain of underwater mountains known as the Juan de Fuca Ridge (center of above image). These peaks straddle the North American and Pacific tectonic plates.

But Axial Seamount, located where two tectonic plates – the Juan de Fuca and the Pacific plates – are moving apart, is one of the most highly studied volcanoes on Earth. Axial was first ...
