Title
Damage Assessment of Eua Island, Tonga
Description
This map illustrates satellite-detected building damage assessment as of 13 February 2018, over the Island of Eua, Tonga, following the passage of the tropical cyclone GITA-18. The analysis was conducted using post-event WorldView-2 images and pre-event GeoEye-1 images as of 28 June 2017. A total of 542 buildings were detected as damaged over the towns of Houma, Ohnoua, Pangai and Tufuvai. According to the pre-building footprints provided by Humanitarian Open Street Map, this represents 47% of the total number of structures in Eua Island. The analysis could have been underestimated due to cloud cover. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.
