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 seashore, 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.
