Current Event- An Earthquake happened in China

There was a earthquake happened at China. And the earthquake is as big as a horrible tornado. There are 107 people that are dead, and 900 students that are buried under the collapsed school, as you can see, this earthquake is much much....... bigger than the earthquake in Taiwan. And some people calculate that this earthquake is 2 more times bigger than the 921 earthquake(which is the biggest earthquake in Taiwan). And there were a water tower fell in the city of Mianyang. This news socked almost everyone in the world and we should all think about it. I think maybe it is related to global warming, and so we need to be alert.
