Document Summary
There is a volcanic eruption that is taking place in iceland as we speak! 31st, and we don"t know how long it will last. It is a fissure eruption that produced more lava in the first five hours than the last big one in the entire eruption. The lava field that was created from this eruption is the largest lava field since some eruption in the 1700s. The volcanic activity from the past 10,000 years largely misses the eruptions along the mid-ocean ridges because they are hard to detect. If a volcano is not along a plate margin, it is likely on a hot spot. Iceland is a hot spot that coincides with a constructive plate margin. Low density magma of the mantle plume lifts the mid-ocean ridge out of the ocean (lifting the island above sea level). Iceland is part of the north american plate, while the east part is a part of the euro-asian plate.
