Earthquake is a 1974 disaster film directed by Mark Robson.
In The Muppet Show episode 502, Gonzo tells Loretta Swit that he hadn't laughed so much since he'd seen Earthquake, after her performance of "I Feel the Earth Move" (in which a gigantic Thog devastates a small city inhabited by Swit's seismologist character).
