The Seychelles island group was struck by a series of powerful tidal surges, resulting from the tsunami, generated by the earthquake off Indonesia on 26 December 2004. As a direct consequence of these tidal surges two people lost their lives, and hundreds of families suffered damage to their homes and livelihoods. The effects of the tsunami were compounded by exceptionally heavy rainfall on 29 December, causing flooding, landslides, and tree/rock falls. In response to a request from the Government of the Republic of Seychelles, the UNEP Asian Tsunami Disaster Task Force organized a Rapid Assessment Mission to Seychelles at the beginning of February 2005. A rapid cost assessment of repairing the damage caused by the tsunami was conducted by the Government of Seychelles in January 2005. The UNEP rapid environmental assessment drew the following general conclusions based on site visits and discussions with Seychelles organizations. This report appeared in November 2005 and is dealing with the consequences more in detail and formulates recommendations for actions.
