Nature disaster is a major adverse event resulting from natural processes of the Earth; examples include floods, hurricanes, tornadoes, volcanic eruptions,... Natural disasters often threaten people's lives, destroy everything on their way, and cause big damage. I have never seen it in real life but through the mass media, from TV, newspapers, or radio... I remember in February this year, there was a big flood swept in the central of Vietnam. It was a terrible memory for people who live there. You know what, in just 1 - 2 weeks, they lost their houses, crops, and all that they have drifting with the floods. Another nature disaster I have heard of is the earthquake. If you are in an earthquake, in 1 first minute, you should find temporary hiding places like under a table, in a bathtub ... places that are sturdy enough to protect your head. If you could move, smoothly turn off the stove, fire. Then, if your house has a basement or shelter, quickly move down there.
