La terre gronde

The catastrophes and disasters that have marked recent history are nothing compared to what science says may be coming down the road. A tsunami that races across the Atlantic Ocean, leveling everything in its path… An earthquake that devastates the central United States… A volcano that collapses in the Pacific northwest, burying major cities under mud and ash… For each of these events it's not a matter of if - it's a matter of when - and that "when" might be sooner than we think. Now, National Geographic will take you inside the Earth itself and into a not so distant future to reveal the threats of DISASTER: SITUATION IMMINENT.
