Re: Over 8,500 killed, 900 students buried as powerful quake hits China
It would take me years to explain that, but the basic principle is this. Certain materials are effected when they expand and contract too radically. For instance, the auto industry had to do away with an engine design... steel block with aluminum heads. Why? Two different types of metal, that expand and contract at different rates when it heats and cools. Now, if you don't have problems with materials when they expand and contract by what is considered to be normal heating and cooling temperatures, that doesn't mean you can just exceed those temps without expecting any problems.
With the earth, there is more than just temperature. There are a host of other elements like magnetism. Disrupting waterways, causing explosions and a whole host of man-made events can obviously cause the earth to react. So, yes... polution, warfare, technology, waste - all these things can cause disruptions - and that includes hurricanes, tornadoes, and even earthquakes. This is why I said earlier... it's not even summer yet.

Since when did pollution cause earthquakes?! :?
