Aftershock

Directed by Nicolás López. With Eli Roth, Ariel Levy, Nicolás Martínez, Andrea Osvárt. In Chile, a group of travelers who are in an underground nightclub when a massive earthquake hits quickly learn that reaching the surface is just the beginning of their nightmare.

An aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to known laws.
