Icelandic Museum Nat Hist & Iceland Geodetic Surv, 1:250,000 geol map. Iceland, the land of ice and fire, is a true paradise for volcanologists. In few places on earth, geology and human history are so closely connected to volcanism as on Iceland. The island owes its existence to a large volcanic hot spot sitting on a mid-oceanic ridge, a unique setting.

This ridge separates the North American and Eurasian tectonic plates, and Iceland is one of the few places on earth that it can be seen above sea-level. These tectonic plates are divergent, meaning that they are pulling away from each other. M. J.
