The Active Volcano in Iceland Askja

One of the largest volcanoes in Alaska is also one of the most remote. Yet, in 1875 it produced one of the nation's largest explosive eruptions, forming a 2.8 mile or 4.5 kilometer wide crater. The volcano I am referring to is known as Askja, which is a complex of calderas surrounded by a 100 kilometer fissure of smaller eruptions. This video will discuss this unusual volcano and the ongoing intrusion of magma underneath its edifice.
