Natural disasters in the world, what are the four major natural disasters in the world

First of all, it is very difficult, even if the accuracy of **out will not be high, maybe 100 times there will be so back** out (it can't be completely denied, after all, there is a Zhang Heng there) Think about it again, the country **arrived**, back to release the forecast??

Accuracy will cause social panic and may not reduce the credibility of the state. It's hard to do.

Rain. Because this kind of localized heavy rain is usually produced by strong convective weather, the whole process is only one or two hours, and there is little forewarning. The geographical scope is also very small, and the current network of meteorological stations is not dense enough, and it is not even observable, and can only be observed with radar.

So... Arriving just causes panic.

It's hard to get it accurate.

Now that technology is so advanced - this is a joke, wonder how many diseases are helpless for humans now, and wonder how many problems there are still that humans can't solve?

The first in the world is Japan, and even Japan can't be accurate.

I don't agree that being accurate creates panic, it only reduces the number of people, and inaccuracy causes panic.

**It's better to build a house stronger, look at Chile is also level 8**, how many people have died, and how many people have died in Wenchuan, China. There are so many ** people in Japan every year, and only how many people die. A strong house is the right way.

Criticism is welcome.

**Hard**.

The ancients were actually quite powerful.

I look up to our ancestors.

Superb !!

Hey, scientists**In the next ten years, there will be more than 6 levels in Jiangsu**, I am in Jiangsu, who will save me?
