This map illustrates satellite-detected areas of visible light at night in western Yemen. The red areas illustrate the areas which were lit at night during 21 July 2015 and best indicate nighttime lights during widespread violent conflict. Conversely, the yellow areas illustrate lighted areas as seen in 20 March 2015, prior to conflict. Areas currently likely to be experiencing electrical blackout conditions at the present time are therefore indicated in yellow. Overall, blackout areas have reduced in size since the previous UNOSAT analysis done using an image from 12 May 2015. Specifically, areas in northern Aden, the city of Sana'a, and some coastal areas do not seem to experiencing blackout conditions as of 21 July 2015. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR -UNOSAT.
