Description of the event
Over 10,000 people are affected by the floods and six people are dead. Roads and railways are impracticable, which caused a lack of access to entire communities, isolating the north from the south of the country. In addition, some 400 houses collapsed and the telephone network was also cut in some flooded areas.
Flooded areas have been sorted into 2 classes: Red areas represent standing flood waters identified with a high degree of confidence. Blue areas represent pre-flood areas. Flood analysis was made using Radarsat data recorded 06 August 2008, and TerrasarX data recorded 04 August 2008. Preliminary analysis not yet validated in the field.
