Tremors 2: Aftershocks is a 1996 American Western comedy horror film and the sequel to the comedy horror film Tremors. In this sequel, the character of Earl Bassett, returning from the first film, is hired to deal with a subterranean "graboid" infestation at a Mexican oilfield. It was directed by S. S. Wilson, and stars Fred Ward, Christopher Gartin, Michael Gross, and Helen Shaver.

After spending all the reward money from his first encounter with Graboids, Earl Bassett agrees to hunt more of the deadly creatures at a Mexican oil refinery for $50,000 each. Knowing that he cannot face the monsters alone, Earl recruits Burt Gummer, another veteran of the incident in Nevada, to supply the firepower. There is only one problem: the Graboids have now evolved into creatures able to attack above ground.

Reviews for the film were mostly positive, with some critics labeling it one of the best direct-to-video sequels ever made.

The film is the second in the Tremors franchise. It was followed by a 2001 sequel, Tremors 3: Back to Perfection.
