Natural disasters take many different forms and can happen without warning. Earthquakes, floods, volcanoes, droughts, typhoons, and hurricanes are all natural disasters.
The earthquake of 26 December 2004 resulted in one of the worst natural disasters in living memory. It was a massive underwater quake and occurred in the Indian Ocean. This caused a huge tsunami (海啸) to cross the Indian Ocean. It destroyed coastlines and communities and brought death and destruction to many people. The survivors needed fresh water, food and shelter as well as medical help. People from all over the world gave money.
The surface of the Earth has not always looked as it does today; it is moving continuously (although very slowly) and has done so for billions of years. This is one cause of earthquakes, when one section of the Earth crashes with another. Scientists can predict where this might happen and the area between plates is called a fault line. However, earthquakes do not always happen on Fault lines, which is why they are so dangerous and unpredictable.
All the disasters are very dangerous and continue to kill thousands of people each year, but they are nowhere near the most dangerous disaster to ever happen on earth. One type of event in the earth's history has regularly killed millions of beings: asteroid (小行星) impacts (撞击). About once every million years the Earth is hit by a piece of rock and ice from space large enough to cause massive destruction (including earthquakes, volcanoes and ice ages) and sometimes to kill entire species. Sixty-five million years ago more than half the earth's species were killed by such a disaster, including all the dinosaurs (恐龙). Disasters on the Earth may seem dangerous, but the biggest threat to humans is likely to come from space.
