Question: is jurassic park 2 on the same island

Answer: No, On Isla Sorna, an island off the Pacific coast of Costa Rica, a young girl named Cathy Bowman wanders around during a family vacation, and survives an attack by a swarm of Compsognathus. Her parents file a lawsuit against the genetics company InGen, now headed by John Hammond's nephew, Peter Ludlow, who plans to use Isla Sorna to alleviate the financial losses imposed by the incident that occurred at Jurassic Park four years earlier. Mathematician Dr. Ian Malcolm meets Hammond at his mansion. Hammond explains that Isla Sorna, abandoned years earlier during a hurricane, is where InGen created their dinosaurs before moving them to Jurassic Park on Isla Nublar. Hammond hopes to stop InGen by sending a team to Isla Sorna to document the dinosaurs, thus causing public support against human interference on the island. Ian, who survived the Jurassic Park disaster, is reluctant. After learning that his girlfriend, paleontologist Dr. Sarah Harding, is part of the team and is already on Isla Sorna, Ian agrees to go to the island, but only to retrieve her.
