Figure 1: Ridge properties as a function of spreading rate. Slow-spreading ridges near mantle hotspots that have an axial rise (for example, the Reykjanes ridge), and abrupt changes in morphology ...

The rift valley lacks an axial high, and is bowed north at its centre. Eleven dredges and three television-guided (TV) grabs (which spot-sample the sea floor) collected about 1,938 kg of rock ...

The Mid-Atlantic Ridge (MAR) is a mostly underwater mountain range in the Atlantic Ocean that runs from 87°N -about 333km south of the North Pole- to subantarctic Bourvet island at 54°S. The MAR is ...

It was a close study, using radar interferometry, of an earth rupture developing into a rare axial rift zone — a future possible ocean basin.

The lava flowed along an 11.8-mile (19-kilometer) rift, creating new seafloor features. Today, the Axial Seamount is the most well-instrumented underwater volcano in the world.

In the depths of the Pacific Ocean, 470 kilometers off the Oregon coast, a drama is unfolding. Axial Seamount, one of the most active underwater volcanoes in the world, is swelling with magma.

Axial Seamount, a submarine volcano 300 miles off the coast of Oregon, could erupt for the first time since 2015, spewing “very fluid lava” into the sea where scientists were recording more ...
