At that point, the lava reaches the dead end of the subway tunnel extension, and bursts out of the ground in a massive geyser. Gator and the officer sacrifice their lives to detonate the final explosive charge by giving Fox the all-clear to ignite the charges. Roark then spots Kelly nearby, trying to retrieve a small boy who wandered off, putting them in the direct path of the collapsing building. Roark barely manages to save both of them from being crushed as the building collapses. The plan is successful, and the lava flows directly into the ocean. Roark escapes from the wreckage with Kelly and the young child still alive. The death toll is nearly a hundred people, thousands injured, and damages in billions.
