Housed within a two-story soundstage containing a recreation of a modern subway station, “Earthquake—The Big One” puts guests in the midst of a fully dressed movie set, ready for filming.  In slightly more than two minutes, the earth literally collapses, simulating the devastation of a 8.3 magnitude earthquake. As the pavement collapses above them, guests face sparking power cables, felled telephone polls, noxious gases, a crashed 18-wheeler containing highly flammable contents, and a massive 60,000-gallon flood.
