Volcano is a 1997 American disaster film directed by Mick Jackson, written by Jerome Armstrong and Billy Ray, and produced by Neal H. Moritz and Andrew Z. Davis. The film stars Tommy Lee Jones in the lead role, Anne Heche, Gaby Hoffmann, Don Cheadle, Jacqueline Kim, Keith David, John Corbett, Michael Rispoli, and John Carroll Lynch. It tells the story of an effort to divert the path of a dangerous lava flow through the streets of Los Angeles following the formation of a volcano at the La Brea Tar Pits. The story was inspired by the 1943 formation of the Parícutin volcano in Mexico.

Volcano was released by 20th Century Fox in the United States on April 25, 1997. It received mixed reviews from critics and grossed $122.8 million worldwide on a $90 million budget.

In downtown Los Angeles, an earthquake strikes. Michael "Mike" Roark, the new director of the city's Office of Emergency Management, insists on coming to work to help with the crisis even though he has been on vacation with his daughter, Kelly. His associate, Emmit Reese, notes that the quake caused no major damage, but 7 utility workers are later burned to death in a storm drain at MacArthur Park. As a precaution, Mike tries to halt the subway lines near the location of the earthquake, though MTA Chairman Stan Olber believes that there is no threat to the trains. Seismologist Amy Barnes believes that a volcano may be forming beneath the city as the earthquake opens a fissure in the fault line, but she has insufficient evidence to make Mike take action.

The next day, Amy and her assistant Rachel venture into the storm sewer to investigate. While they take samples, the San Andreas Fault unleashes a strong earthquake that strikes the city. Rachel falls into a crack and is killed by a rush of hot gases. A subway train derails from falling debris, and a power outage occurs across the entire city. Later, a small cinder cone volcano erupts from the La Brea Tar Pits. As Mike helps injured firefighters out of the area, lava begins to flow down Wilshire Boulevard. It incinerates everything in its path and kills two firefighters in an overturned fire truck. The father and daughter become separated, as Kelly is injured when a lava bomb burns her leg and is taken to Cedars-Sinai Medical Center along with other patients.

Meanwhile, Stan leads his team through the tunnel to the derailed train to search for survivors. While they save everyone aboard, Stan rescues the driver just as lava reaches the train, causing it to disintegrate. Stan sacrifices his life by jumping into the lava flow to throw the driver to safety.

Mike, Amy and LAPD lieutenant Ed Fox devise a plan to use concrete barriers to create a blockade, which obstructs the lava. A fleet of helicopters dumps water collected from the ocean to subdue the lava and volcano, forming a crust and making the plan a success. But Amy thinks the magma is still flowing underground through the subway because ash is still falling. When Mike helps her confirm her suspicions, she calculates that another eruption will occur at the end of the Red Line at Cedars-Sinai and, after calculating the speed of the flowing lava, determines that it will reach the end of the tunnel in 30 minutes.

Mike devises another plan to demolish a 22-story condominium building to block the lava from flowing toward the hospital and the rest of the West Side, redirecting it into a nearby storm drain. As the lava arrives, Mike's co-worker Gator Harris and an LAPD Bomb Squad officer (trapped under debris) sacrifice their lives to detonate the final explosive charge. Mike then spots Kelly nearby, trying to retrieve a little boy she was watching who wandered off; the two are directly in the collapsing building's path. Mike barely manages to save them from being crushed. The plan succeeds, and the lava flows directly into the ocean. As it begins raining, the trio emerges from the rubble unscathed and reunites with Amy before heading home.

At the tar pits, the volcano (which has since been named "Mount Wilshire") has taken shape above ground and remains active.
