Mt Eyjafajallajokull
MT Eyjafajkallajokull is situated in the South of Iceland, the volcanic eruption occurred on the 14th Of April, 2010. Though it was not a huge eruption, the impacts were huge.
The cause of the eruption?
Iceland in general is an active area, this is because it is situated on a hotspot that created Iceland itself. The picture on the left (bottom) is the volcanic region of Iceland, where the mantle is hotter, thus easier to break through. A Hotspot is a volcanic region where the mantle is hotter than other areas, therefore when there is an opening, the magma escapes causing a volcanic eruption. This is what happened with the Mt Eyjafajallajokull eruption. It was on a constuctive boundary, where the Eurasian plate and the North American plate diverge (move away) away from each other. An opening is then formed, the magma can thus can erupt. A divergent boundary is when two continental plates (not always) move away from each other, creating an opening in the crust, thus the mantle/magma can erupt.
