Earthquake (1988) Earthquake: The Big One, which replaced the Tower of London set, is a simulated 8.3 Richter scale earthquake inside a sound stage set to look like a San Francisco subway station. The attraction features a gimball which shakes the tram, a burning gasoline truck that collapses through the roof, fire and spark effects, a derailing subway train, and a flood of water. The entire attraction resets itself in just 1 second ready for the next tram.

Towards the end of the tour you get to see the largest blue screen in the world, which was a big part of the end of Apollo 13 where they dropped into the ocean.
