Earthquake was released in 1974 during an era when disaster films were in vogue. It is overall a good movie, though some parts and performances are better than others. The subplot concerning Charlton Heston and his love affairs takes up too much time and seems to be thrown in to pad the film. The best performance is by George Kennedy as a embittered police officer trying to do his best in a bad situation (Kennedy even saves a bruised, scared dog at one point - a scene that sounds hokey but really isn't). The special effects are good, though the scenes with the elevator and the cattle truck seem a little unbelievable. Earthquake is a lot better than many disaster films, and while not a dramatic masterpiece it still holds up well almost 30 years later.
