You've had a chance to vote for Group A (although voting for all groups will be open until June 26 at noon EDT), so now its time to move to Group B: Australia, Chile, the Netherlands and Spain. Australia: If you're looking for a continent free of most tectonic disasters -- earthquakes and volcanoes -- you could pick no better than Australia (however, to balance things out, pretty much all plants and animals are poisonous, right?) The nation itself only has a few volcanic fields that may have erupted in the last 10,000 years, including the Newer Volcanic Province in the south and the Atherton Volcanic Field in the north. To find any real active volcanism, you need to travel into the middle of the Indian Ocean, where you find Mawson Peak (see below) on Heard Island -- about as remote as you can get, but the volcano might host an occasional lava lake at the summit crater.

NASA Earth Observatory Chile: If you need to pick a favorite for the Volcano World Cup, you need look no further. Chile has at least 137 potentially active volcanoes and thousands more volcanic features that cover the slender nation tip to tip. It is hard to pick just one volcano to represent the country's plethora of volcanism, but this shot of Chaitén erupting in early 2009 captures just how powerful some of these volcanoes are.

NASA Earth Observatory The Netherlands: Like many European powers, the volcanoes it can claim as its own are not on the continent. Instead, the far-flung pieces of conquest are where the eruptive prowess lies. For some nations, whatever is left of their former empire is a mere shadow of what it once was. Take the Netherlands for example. Had the Volcano World Cup existed in the last 1800s, the Netherlands would dominate thanks to its domain over Indonesia. Today, the nation is left with vestiges of empire in the Lesser Antilles, including The Quill (see below) on St. Eustatius, which last erupted last recently as 400 AD.

NASA Spain: The defending real World Cup champions are another nation whose volcanic prowess comes from its colonies. There is the Garrotxa Volcanic Field covered in small cinder cones, mostly dating back tens of thousands of years, on the mainland of Spain. However, if you're looking for active volcanoes, you need to head out into the Atlantic to the Canary Islands. There you'll find a multiple of volcanoes that have erupted frequently over the past century, including El Hierro (below), Teide and Cumbre Vieja on La Palma.
