Some high-def volcanic action in Iceland

I’ll admit to having a fondness for bright, shiny things. Perhaps that’s why I can spend hours staring at minerals in thin sections on the microscope and not get tired of it. This fondness also extends beyond the world of the microscope to things on a macro level. Case in point- this awesome video I found on Vimeo of volcanic eruptions occuring in Fimmvorduhals, Iceland. It was shot in HD and looks spectacular when viewed as such (be sure to go full-screen).

What you’re seeing here is magma that started at the earth’s mantle and then erupted from fissures on the surface as lava.This video shows the surficial portion of the much longer Mid-Atlantic Ridge that pretty much runs the length of the Atlantic Ocean.This is where you can see the volcanic action associated with divergent plate boundaries or the part of the earth’s crust where two plates are moving away from each other. In this video, we get to see the part of the Mid-Atlantic Ridge where the North American and Eurasian plates are moving away from one another.
