  • Mayor Lewis: The governor and I aren't even in the same party. If this turns out to be a false alarm, he'll make me out to be the biggest fool west of the Mississippi.
    Dr. Stockle: Second biggest. I'll top the list.


  • The first film to be presented in "Sensurround," a special low-frequency bass speaker setup consisting of four huge speakers loaned by distributors to select theatres showing the film. This system was employed only during the quake sequences of the film, and was so powerful that it actually cracked plaster at some movie theaters. "Sensurround" was employed in only three other films released by Universal: Midway, Rollercoaster, and the theatrical release of Battlestar Galactica.
  • Some of the scenes of panicking extras in the movie theater is footage from Torn Curtain.
  • Walter Matthau asked to play the drunk in the bar after seeing the scene description "A drunk sits at the end of the bar" in the shooting script. Despite the director's objections, and the fact that the character originally had no lines, he insisted that he play the part. Matthau got his way, and his performance provided much needed comedy relief.
  • The reservoir dam that breaks in the film was based on the real-life St. Francis dam disaster in 1928, near Mulholland Falls.
  • Before stereo TV sound was commonplace, NBC aired "Earthquake!" with the soundtrack simulcast on local FM radio stations so that viewers could recreate "SenSurround" at home.
