Largest Volcano - Yellowstone Volcano

The ultimate of volcanoes
Volcanoes have been around on earth since the very beginning of earth's long, 4.5 billion year history. When it comes to extremes in nature, there's not much else that compares to the violent eruption of the blood and guts of the earth that is a volcano. With enough destructive force to level mountains, or build new ones, volcanoes are the undisputed champions of the extreme forces of nature.
Volcanoes are rarely minor incidents of geology in action. As destructive and powerful as even the smallest volcanoes are, there have been even bigger, really gigantic eruptions in earths past that have dwarfed even the most awesome volcanoes we've seen during our brief history. Even small volcanoes can pack a seriously destructive wallop, but they can't compare to the most awesome earth force ever wielded by nature - the Extreme Volcanoes.


Forging new earth
Earths Crucibles of Creation come in a variety of flavors. Volcanic activity on planet earth takes on many different forms, from cinder cones spewing forth glowing hot cinders, to billowing clouds of hot ash and gases being blown into the sky, to slowly oozing rivers of molten lava rushing down the sides of great peaks. Though each eruption varies they all share one thing in common; they are fueled by the superheated magma beneath the earths crust. All volcanic activity has the dual role of destruction and creation. Though many living things may die in the drowning fires of a volcanic eruption, the magma fueling the volcano is responsible for the building of new crust as newly emerging lava cools into solid rock. Because of the extremely rich mineral content of volcanic rock, as it breaks down through weathering it is some of the most incredibly fertile soil on earth, giving a foothold for new life to thrive.
