Well, actually they did mention using seismic activity as a weapon. The basis of the movie was that this weapon caused the outer core of the Earth to stop spinning.
Huh?
The _outer_ core of the Earth is _liquid_.
The _inner_ core is _solid_ and rotates within the liquid outer core independently of the mantle & crust, completing about one extra rotation (compared to the mantle/crust) about every 400 years. It is currently thought by many geologists & planetary scientists that the "stirring" of the electrically conductive liquid iron outer core due to the difference in rotation speeds between the inner core and the mantle is what generates the Earth's magnetic field.
This movie did a pretty good job of destroying any real scientific plausibility. The first hour was not bad and the special effects of that first hour were great. The shuttle landing/crash was awesome.
But once they launched into the earths crust, the movie was pretty much down hill from there (pun intended).
wait until this one �hoes� to the dollar theater.
It's going to dig it's way there?
