The rumbling sound begins. It builds up, getting louder and louder. The ground begins to shake. Off in the distance, columns of smoke begin to rise from the volcano. Finally, it erupts in a huge explosion of rocks, debris, fire, and ash, sending hot vapors hundreds of feet into the air. Volcanoes - whether erupting suddenly or quietly, in a giant fanfare or with a quiet lava flow - are perhaps nature’s most awesome and incredible show of force. This natural disaster, with its rich history of legend, is an incredible machine. Read on to learn more, see pictures, and see if you can take the challenge.
