Ngorongoro Crater (Tanzania). At 610m deep and 260 sq km, this is the largest unflooded caldera in the world. A blue-green vision from above it's a haven for engangered wildlife and Maasai livestock. The crater was formed three million years ago when a giant volcano, which could have been as high as Kilimanjaro, exploded and collapsed. The caldera formed the concentric fractures in the crust cracked down to a magma reservoir deep underground. (Photo by John Bryant/Getty Images)

Ismail Mustafa, seen in 2007. “I was collecting mushrooms on the hill near here. I didn’t see the mine. There was a huge explosion. When I woke up I saw that both my legs were gone; I thought my life was over. My brother and another guy were with me. They made a stretcher from sticks and tied it together with clothing. It took two hours to get off the mountain. ‘My daughter has also been injured. She found a shell and brought it into the house and put it on the fire. She didn’t know what she was doing at the time – she was only three. She is blind and has lost an arm”. (Photo by Sean Sutton for the Mines Advisory Group/The Guardian)
