report UNOSAT

January 2013 - Cyclone Evan is a powerful category 4 storm that tore through the Pacific in December 2012 and was initially compared to the dramatic storm that hit the same region in 1993. On 15 December, as the cyclone unleashed its power provoking death and destruction, UNOSAT was activated by OCHA with a request to deliver rapid mapping over Samoa, and then again on 18 December 2012 for Fiji. While Samoa had little forewarning of Evan’s arrival, Fiji benefitted from an early alert and could prepare for the storm landfall, which caused extensive destruction but no casualties.

This atlas map product 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 9 separate focus maps are included, highlighting damage sites identified from post-disaster satellite imagery collected from 30 September to 4 October 2009. Damage identification was restricted by the partial coverage and spatial resolution of the imagery, as well as by cloud cover. It is probable therefore that damages have been underestimated.
