The first feature film to use the special sound effect process Sensurround, Earthquake brought in $36,250,000
for Universal during its theatrical run. Although the DiscoVision jacket calls for the film to quake for 129
minutes, the movie only runs 122 minutes. The 129 minute version appears to be the run time of the television
version. All theatrical reference material lists the run time for Earthquake at 122 minutes. It left the
DiscoVision catalog after the October 1980 edition. Frame counts have been known to vary from copy to copy
indicating more than one mastering of the title.
MCA Home Video reissued Earthquake in October 1987 as a 3 sided CLV/CAV title (Catalog #: 10002).
MCA/Universal Home Video released a Widescreen version (2.35:1) of Earthquake in August 1994 (Catalog #: 42072).
