From a research submersible, scientists saw hardened lava, dead tube worms and orange flashes from an eruption in the East ...

Mid-ocean ridge basalts (MORBs), located far from subduction zones, are typically thought to be unaffected by subduction processes. However, some MORBs display arc-like geochemical signatures ...

By comparison, the temperature of crustal fluids can reach 400 degrees C at hydrothermal vents in the Mid-Atlantic Ridge, where tectonic plates are diverging and new oceanic crust is being formed.

Researchers in a submersible could hardly believe their eyes, or their luck, when they saw a clearly active eruption along an undersea volcanic mountain chain.

These zones include: the Pacific Ring of Fire around the Pacific Ocean the Mid-Atlantic Ridge, a mid-ocean ridge that extends along the floor of the Atlantic Ocean southern Europe There are ...
