We've made it to the last Group of the Volcano World Cup! If you haven't yet, vote in the rest of the Group Stage: A, B, C, D, E, F and G Group H has one of the Volcano World Cup favorites plus some upstarts: Algeria, Belgium, Russia and South Korea Algeria: I bet you didn't realize that Algeria has a number of potentially active volcanic fields. Most are clusters of small cinder cones and lava flows and most are remote -- I mean really remote. Of the 4 major volcanic fields, only one as more than 1,000 people living within 30 kilometers: the Manzaz Volcanic Field (see below). Thanks to their location, we don't know a lot about any of Algeria's volcanic fields, but they have likely been active in the last 10,000 years based on what other deposits they overlie. Interestingly, these magmas likely did come from deep in the Earth as they are chock full of mantle xenoliths (blocks of foreign rock).
