Mount Sibo

'Mount Sibo''' is an active volcano located in the northern part of Isla Nublar.

Mount Sibo began to erupt during the events of the film, as Owen Grady, Claire Dearing and multiple other personnel returned to begin a rescue operation to save the dinosaurs. While the island was rocked by tremors consistently, eventually, lava began to force its way to the surface.

Claire and Franklin Webb encountered a Baryonyx underground, as lava began to consume a sub-ground level outpost, with Owen suffering from near complete paralysis from a tranquilizer, while lava began to overrun the region he was left behind in.

Once Claire, Franklin, and Owen all reunited, the volcano began to erupt in full force, causing a large, multi-species stampede, with a pyroclastic flow forming. Said flow would run right to the island's cliff, forcing any dinosaurs and animals caught in its path to jump, including the three people left behind.

As the trio recovered from their jump, a barrage of volcanic rock from the still continuing eruption forced them to hijack an abandoned gyrosphere to escape. In spite of their escape, a single Brachiosaurus was left behind at the ship's dock, and watched as the flows of fire and ash consumed it, leaving Mount Sibo, and Isla Nublar in a volcanic inferno. It’s assumed that the volcano destroyed the island and all life on it.
