タワーリング・インフェルノ
John Williams' music for "Earthquake" was the second of his trio of scores for large-scale disaster films, having previously scored "The Poseidon Adventure" and following with "The Towering Inferno". Williams scored both "Earthquake" and "The Towering Inferno" in the summer of 1974, both scores showing similarities to one another (notably "Earthquake's" theme and "The Towering Inferno's" love theme sharing the same eight-note melody). The music of the song "C'est si Bon" by Henri Betti is played on the guitar in the middle of the film.
