    UNOSAT code FL20231105SOM This map illustrates satellite-detected surface waters in Bu'aaler and Saakow District, Juba Dhexe Region and Afmadow District, Juba Hoose Region Somalia as observed from a Sentinel-1 image acquired on 07 November 2023 at 02:54 UTC. Within the analysed area of about 7,600 km², about 180 km² of land appear to be flooded. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to 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 backscattering properties of the radar signal.

    UNOSAT code CE20231007PSE UNOSAT conducted a satellite-imagery based comprehensive damage assessment to detected damage and destruction to structures within the area of interest in the Deir Al-Balah Governorate, Gaza Strip, using an image collected on 21 October 2023 and compared it to an image collected on 15 October 2023. According to the satellite imagery analysis, UNOSAT identified a total of 197 destroyed structures, 143 severely damaged structures, and 435 moderately damaged structures, for a total of 775 affected structures as of 21 October 2023. This corresponds to less than 2% of the total structures in the Deir Al-Balah Governorate. The most affected area appears to be the Al Bureij Camp neighborhood, where the number of damaged structures per square kilometer is the highest, followed by the Al Awda neighborhood. Among the newly affected structures, UNOSAT identified a mosque, namely the Al-Salam Mosque, visibly destroyed. Additionally, UNOSAT identified 42 affected road sections, either by impact craters or by debris. This is a preliminary analysis and has not yet been validated in the field.

    UNOSAT code CE20231007PSE UNOSAT's satellite imagery-based damage assessment detected damage and destruction to buildings within the area of interest in the North Gaza Governorate, Gaza Strip, based on an image collected on 15 October 2023 when compared to images collected on 1 May 2023, 10 May 2023, and 18 September 2023. According to satellite imagery analysis, UNOSAT identified 927 destroyed structure, 1216 severely damaged structures and 3121 moderately damaged structures, for a total of 5264 buildings. This corresponds to around 15% of the total structures in the North Gaza Governorate. One of the most affected area appears to be the one between Al Farata and Hai Abu Ghazala neighborhoods (inset 1). Among the affected structures, UNOSAT identified one school compound, namely the Beit Hanoun school, which eastern wing got severely damaged. Additionally, UNOSAT identified 271 affected road sections, either by impact craters or by debris. This is a preliminary analysis and has not yet been validated in the field.

    UNOSAT code FL20230912LBY, GDACS Id: 1102204 On the night of the 10th of September 2023, after its journey through the Mediterranean Sea, the storm Daniel brought heavy rains that triggered floods in Benghazi, Almarj, Al Jabal Al Akhdar and Derna Governorates, in northeastern Libya. The increase of water levels in the region caused the collapse of two dams located upstream Derna River and the consequences was tremendous. The dam breach released a massive amount of water and a huge flood wave wiped out entire neighbourhoods in the city of Derna. Hundreds of people were reported missing by the Libyan Red Crescent Society. According to the Libyan National Meteorological Centre, the storm reached its peak with winds going up to 70-80 km/h. This led to the falling of electricity towers and tress causing communications interruption. Between 150 – 240 mm were reported and caused flash floods in several cities. Al-Bayda have recorded the highest daily rainfall rate: 414.1 mm in the night of the 10 to 11 September 2023.

    UNOSAT code EQ20231008AFG, GDACS Id: 1394952 This map illustrates the level of damage induced by the 07 October earthquake (M6.3) in settlements North and North-West Herat as observed from very high-resolution images Pléiades acquired on 09 October 2023. UNOSAT has analysed 4 areas for a total of 750km² and detected 56 affected settlements, amongst which 38 are moderately affected, 3 severely affected and 15 are almost destroyed. The map illustrates also the coseismic surface displacement interferogram related with the 7 October 2023 earthquake as deduced using a pair of SAR images acquired on 07 Oct. 2023 and 25 Sep. 2023. Narrow fringes translate a higher surface displacement. This is a preliminary analysis and has not yet been validated in the field.

    UNOSAT code FL20230912LBY, GDACS Id: 1102204 Status: Power outage observed. Further action(s): continue monitoring Based on the estimation from night-time light, power supply of Derna reduced by more than 90% after the floods. As of 24 September 2023, the power supply of Derna has been restored to about 80% of its pre-floods level. As of 19 September 2023, the floods affected areas in Derna were still in blackout. Night-time light within the floods affected areas accounts for 30% of Derna’s total night-time light. Based on the estimation from night-time light, power supply of Al Bayda reduced 60% after the floods. As of 24 Sept. 2023, the power supply of Al Bayda has been restored to 90% of the pre-floods level. After the floods, Derna suffered the most severe power outage. Outer areas of Al Bayda had more power outage than the city center. On 24 September 2023, power supply in most areas of Derna and Al Bayda has recovered to the pre-floods levels.
