This map illustrates satellite-detected areas of building damage, road obstacle, damage to other infrastructure, tree fall areas due to tropical cyclone Evan in southern part of Upolu Island in Samoa as of 19 dec 2012. Damages were detected using high resolution satellite image Pleaideas taken on 19 dec 2012. The damages visible from the satellite are roof damage and complete destruction of the buildings which was detected comparing to pre disaster GEOEYE image taken on 8 oct 2012. It is likely that damages have been underestimated in places where damages did not occur in the roof but other parts of the structure. Road obstacles, tree fall and other infrastructure damages were detected in a similar manner comparing pre and post disaster images. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR/UNOSAT
