Funny how those volcanoes seem to pop up along the mid atlantic ridge like that huh?
Ok, here’s what is really going on. geologic evolution,
The tectonic plates are moving. The opening of the mid Atlantic rift allows magama to flow upward at the Icelandic openings that are called volcanoes. While they exhibit volcanic activity, they are in fact lengthwise splits in the earth crust and are spreading.
Meanwhile, thousands of miles away, other plate edges are being scrunched together. This scrunching produces earth quake.
As the Mid Atlantic rift opens wider, the other plate boundaries narrow and there is subduction and quakes.
For every action, there is equal and opposite reaction
