Waves in Earth's mantle created by the rifting of continents may peel the planet's crust from below, feeding volcanoes in the middle of the ocean.

The most accurate 3D images of the interior of a volcano, Axial volcano off Oregon's coast, ever captured have implications ...

Researchers thought that Axial Seamount might erupt in 2025, but recent data suggest the underwater volcano could take a bit ...

A program designed to study the mid-ocean ridge system and enhance understanding of the relationship between the geological processes that lead to planetary renewal in the deep ocean and life forms ...

Ken Sims, a professor in UW’s Department of Geology and Geophysics, recently received a $325,841 National Science Foundation grant to look at understanding the processes and timescales of basalt ...

Scientists from the Woods Hole Oceanographic Institution (WHOI) have identified a new type of ocean ridge that is spreading so slowly that Earth's mantle is exposed over large regions of the sea floor ...

EUGENE, Ore. - Feb. 7, 2018 - A record of volcanism preserved along ancient mid-ocean ridges provides evidence for heightened worldwide magmatic activity 66 million years ago just after the Chicxulub ...

Scientists have discovered a new "ultra-slow" class of ocean ridge involved in seafloor spreading. Investigations in the remote regions of the planet--in the far south Atlantic and Indian ...

ABSTRACTAs part of the suite of multidisciplinary investigations undertaken by the Ridge 2000 Program, new multichannel seismic studies of crustal structure were conducted at the East Pacific Rise ...
