Its 4200 km² of earthly area spread  themselves on a maritime zone of more one than two million km². It is formed of 5  archipelagos with tropical climate: Marquises islands, Society islands (with Tahiti and the  administrative center Papeete), Australes islands and Gambier islands, all of volcanic origin.  To the opposite, the atolls of Tuamotu (880 km², 12374 hab), are of coral origin.
