Abstract
French Polynesia is frequently struck by transoceanic tsunamis originating from around the Pacific. The numerical modelling of five scenarios defined among threatening source areas has been performed on seven Polynesian sites. The results show that the Marquesian bays are consistently most affected, while the sites in Tahiti and Rurutu are significantly exposed, though less heavily. The tsunami hazard has been then mapped for whole Polynesia. Major tsunamis are expected to hit Marquesas, and Rurutu (Australes), but less frequently. An elevated hazard level is defined for the other Australes and for several Society Islands (especially Tahiti). Tuamotu atolls and other Society Islands are only moderately exposed.
