This by far has to be the biggest budget disaster movie of all time. All others over the years pale in comparison, as this is not just about 1 earthquake in LA or a Towering Inferno in another city. This disaster affects the entire world. The special effects were done so well that I can only imagine that is how it would be if something like the movie portends will happen. However, so much was happening at one time it was hard to keep up with the fast pace during disaster sequences, which are spaced out pretty good (don't all happen at one time).
