On 13 September 1999, a local tsunami, comprising two waves separated by a few minutes, hit the village of Omoa, on the island of Fatu Hiva, French Polynesia. It inflicted serious damages to structures built close to the sea-shore, in particular to the local elementary school. The tsunami was generated by the collapse of a basaltic cliff, located 3 km to the southeast of Omoa, along the coastline. The volume of the landslide is estimated to range from 2 to 5 million m3, of which 60% fell into the sea. A preliminary simulation of the tsunami provides an acceptable explanation of wave amplitudes, as well as an estimate of the origin time of landslide.
