Smart disasters
In Hollywood, there is always a rule, the disaster have to be smart, they have intelligence to follow cars or airplanes, such as this "MegaFault", "10.5", and "2012".
shareIt is remarkable that in the movie, the crack following the earthquake had to move along the highway and roads about a hundred meters following the vehicle they were driving. It appears that natural disasters, just like traffic, have to move along roads. Absolutely hilarious.
