Title
Satellite detected water extents in Vientiane Capital, Lao PDR as of 18 September 2024
Description
**UNOSAT code: FL20240913LAO** This map illustrates the floods using Sentinel-1 images acquired on 18 September 2024 at 06:00 local time. Within the analyzed area of approximately 7,000 km², around 230 km² of land appears to be affected by floodwaters. The extent of the flooding has increased by approximately 50 km² since the previous observation on 13 September 2024. Based on WorldPop spatial demographic data, an estimated 26,000 people are currently exposed or residing near the flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT). Important note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to the backscattering properties of the radar signal.
