Original (1989) television commercial for the Earthquake: The Big One attraction on the Studio Tour at Universal Studios Hollywood. The Earthquake attraction is an 8.3 (on the Richter scale) earthquake inside a soundstage, designed to make it look like a San Francisco subway station. They have a hot set; a hot set is a stage in which various props stay in use and cannot be moved. The attraction features a gimbal which allows it to shake the tram, a burning gasoline truck that collapses through the roof, fire and spark effects, a derailing subway train, and a flood of 60,000 gallons of water. The attraction resets itself within just 15 seconds to prepare itself for the next tramload of guests. #UniversalStudiosHollywood #UniStudios #UniversalHollywood #UniversalIG #TeslaCoil #ThemeParkHistory #UncleCarl #UniversalStudios #StudioTour #TramTour #BacklotTram #SubwayTrain #SanFrancisco #BART #Backlot #Jaws #PsychoHouse #BatesMotel #HotSet #UniversalStudiosTour #80sCommercial #Hollywood #Ric...
