No, Haiti was a natural geological process and this was probably as well, I know there is a lot of limestone in the Austin area and that probably extends down to San Antonio as well. Limestone forms caves, and when a cave gets too close to the surface, you get sinkholes.
Not even close dude, in Armageddon Bruce Willis and a crew of misfits had to blow up a huge asteroid before it hit Earth. This is a lot more like Earthquake, where Charlton Heston and Ava Gardner try to survive after a huge earthquake hits Los Angeles.
I saw someone talking about The Phil Schneider Story on the blogs this morning, first time I ever read something like that. Yegads and little fishes!!!
