Why are earthquake's so dangerose?

The earth itself is not a dangerous place, more along the lines of the people living on earth. It depends on what your opinion lies on, because to some, earth is a dangerous place due to the different weather climates. In some places it becomes extremely cold, or a massive heat wave strikes. But to an answer if earth itself is a dangerous place because of humans such as ourselves, it is because of the different opinions and different religions. The argument will always land on if the opinions are right, or if the religion is correct. That is why in most cases the world is sometimes a dangerous place.

It is made violent planet by human, if we look after earth, it will look after us.
