A look ahead at the different types of cataclysmic events that could extinguish the human race, from massive volcanic eruptions, mega tsunamis and out-of-control fires to an asteroid impact.
How humans might cope with falling rocks and debris, tsunamis, furnace-like temperatures, and fires in the aftermath of a killer asteroid; 65 million years ago, an asteroid led to the downfall of the dinosaurs.
If a rogue planet was on a collision course with Earth, its gravity would tear apart the Moon, stir up supersonic winds, trigger earthquakes, and pull the Earth to pieces.
A gamma ray burst from two colliding stars hits the atmosphere, wiping out half of the population on Earth, while the other half faces a slow death from ultraviolet radiation and starvation.
After a volcanic hyper eruption blows through the surface of the Earth, molten rock slams into cities, shock waves bring down buildings, volcanic gas blocks out sunlight, food chains collapse, and a famine threatens the future of humankind.
A scenario in which Earth is pulled out of its orbit, sending it on a collision course with the sun and triggering massive hurricanes, sandstorms and a deadly heat wave.
