Volcano (1997).
Tommy Lee Jones was the only good thing about it. Otherwise you got a cliché overworked-father/estranged-daughter subplot, ham-fisted social commentary, unnecessary scenes of pets and children in danger, and a multitude of scientific inaccuracies (e.g. a dam made of ordinary concrete barriers will not stop a river of lava, you can't stand that close to lava without being boiled alive, LA is near a fault where tectonic plates move alongside each other, negating the possibility of a volcano, etc.).
