map UNOSAT

This map illustrates areas of satellite-detected destroyed or otherwise damaged settlements in Buthidaung, Maungdaw, and Rathedaung Townships in Northern Rakhine State in Myanmar. Analysis primarily used satellite imagery collected on multiple dates from August 2017 to March 2018. Satellite analysis combined with information on settlement locations in Myanmar indicate that approximately 392 towns and villages from a total number of 993 were affected. This includes 96 out of 371 in Buthidaung, 277 out of 399 in Maungdaw, and 19 out of 223 in Rathedaung.

This map illustrates satellite-detected landslide at in Bukalasi and surrounding areas located close to Mount Elgon in Manjiya District, Eastern Region, Uganda, as seen on Pleiades-1 satellite imagery with 0.5m resolution, collected on 13 October 2018. The analysis of the image shows that landslides and overflowed waters/mud seem to have hit Bukalasi along the stream and have potentially affected several houses and also caused cut of roads. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.

This map illustrates an analysis of the evolution of satellite-detected surface waters in Bayelsa State, Nigeria, based on satellite data recorded on 16, 21, 22, 28 September and 03 October 2018. Before the national flood had been declared by the government of Nigeria on 18 September 2018, a total surface of 79,902 ha was detected as inundated within Bayelsa State, as of 16 September 2018. On 21 and 22 September 2018 an additional surface of 5,280 ha inundated areas were detected, representing an increase of the surface waters of 7%.

map UNOSAT

Potentially affected settlements in Tuba area caused by the passage of Tropical cyclone Mangkhut -18 that made landfall in Philippines on 15 September 2018.

Additional damage was caused by landslides triggered after the cyclone traversed the Philippines. Damaged roads and obstructions along transportation networks are visible as of 21 September 2018. The runaway of the airport seems also affected. Overall the level of damage is moderate. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.

map UNOSAT

This map illustrates the satellite-detected surface waters extent in the southern provinces of kien Giang, An Giang, Dong Thap & Can tho as observed from the Sentinel-1 SAR images acquired on 16 & 28 August 2018. In the analysed area, an increase of surface waters is observed mainly in agricultural and paddy fields areas. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks and within built-up urban areas because of the special characteristics of the satellite data used.

map UNOSAT

This map illustrates the satellite-detected surface waters extent in Lang An province and in the southern part of Cambodia, as observed from the Sentinel-1 SAR images acquired on 16 & 28 August 2018. In the analysed area, an increase of surface waters is observed mainly in agricultural and paddy fields areas. In addition, using WorldPop data, we can estimate that ~200,000 people are living within or close to flooded zones in the province of Lang An.
