Overview of Tsunami Damages on Tutuila Island, American Samoa (as of 20 Oct 2009)

This map illustrates satellite-detected areas of likely building and vegetation damages caused by the magnitude 8.0 earthquake and resulting tsunami on 29 September 2009. A total of 11 damage sites were identified based on post-disaster satellite imagery collected on 2-3 October 2009. Each site has a corresponding high resolution focus map within the PDF document. Damage identification was significantly restricted by heavy cloud and shadow coverage, as well as by spatial resolution of the imagery. It is probable therefore that damages have been underestimated. This assessment is a preliminary analysis & has not yet been validated in the field.
