When this movie originally aired NBC had public service announcements showing what people could do to protect and prepare themselves for an earthquake. The movie itself addresses this issue in a scene in which Clare and her daughter Heather go over the earthquake kit that Clare has put together. The kit includes having a first aid kit, water purification tablets, a battery powered transistor radio, fire extinguisher, several flashlights, matches, 500 dollars cash (due to the fact that with computers down banks might be closed for awhile), and a gun to protect themselves from looters. Clare also takes her daughter outside and has her daughter show her how to properly shut the house's main gas valve off. This is suggested to do to prevent gas main explosion. Clare also keeps in her car a backpack with much of the same equipment The kits and shutting off the gas valve are things that prove very valuable to both Clare and Heather after the quake.
Footage of the San Bernadino train wreck that occurred in May 12th,1989 involving The Southern Pacific railroad was used in the montage showing the aftermath destruction of the earthquake.
