Earthquakes and Mega Cities

   Fifty percent of the world's super-cities are now located in zones where earthquakes of 7.5 (Richter) magnitude are likely. According to EOS, the weekly newspaper of the American Geophysical Union, a massive earthquake each century could cause devastating damage and hundreds of thousands of deaths unless buildings are constructed to be more earthquake resistant.

   There has never been a devastating mega quake before because it simply wasn't possible. That is mega cities are a recent phenomena. There are now 200 mega cities and that number is expected to double before the earth's population stabilizes.
