# Libya Floods: Damage and Flood Proxy Maps, Sep 2023 The **Earth Observatory of Singapore – Remote Sensing Lab (EOS-RS)** produced these damage and flood proxy maps for Libya Floods (Sep 2023) from synthetic aperture radar (SAR) satellite images. Each map is a separate ZIP below with its GeoTIFF, a KMZ for Google Earth, the PNG figures and a text file describing how it was made and how to read it. ## Maps in this dataset - **EOS-RS Damage Proxy Map: Libya, Floods, 12 Sep 2023, v0.9** - **EOS-RS Damage Proxy Map: Libya, Floods, 12 Sep 2023, v0.9** - **EOS-RS Flood Proxy Map: Libya, Floods, 12 Sep 2023, v0.5** **More map details and files:** **More map details and files:** **Credits:** Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), Contains modified Copernicus Sentinel data (2023), Validated with FirstLook Imagery © 2023 Maxar

GLIDEnumbers are GLobal unique IDEntifiers for Disasters. Each disaster is registered in a record that contains a GLIDEnumber that uniquely identifies it and allows information to be interoperable across multiple disaster information sources, both structured and textual. Accessing disaster information can be a time consuming and laborious task. Not only is data scattered but frequently identification of the disaster can be confusing in countries with many disaster events and across borders. To address both of these issues, Asian Disaster Reduction Center (ADRC) proposed a globally common Unique ID code for disasters. Among the institutions using actively GLIDEnumbers are UN-OCHA (ReliefWeb, FSCC, HDX), UNDRR, UNDP, WMO, IFRC, FAO, the European Commission and the Centre for Research on the Epidemiology of Disasters (CRED), among many others. Country datasets are only produced for countries with at least one GLIDE event since 1 January 2022. The global dataset contains all events available from the GLIDE API, including those not assigned to a country.

**UNOSAT code FL20230912LBY, GDACS Id: 1102204** Live web map showing analysis related to floods in Libya following the strom Daniel in the north-eastern part of Libya.

**UNOSAT code FL20230912LBY, GDACS Id: 1102204** This map illustrates satellite-detected flood impact in 4 dams over Benghazi and Almarj governorates, East pronvce, Libya, as observed from optical very-high resolution satellite imagery. Dam reservoirs appears to be filled over the 4 dams. 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).

**UNOSAT code FL20230912LBY, GDACS Id: 1102204** Status: Significant light loss observed. Further action(s): Continuous observations planned for full assessment Severe floods in Libya have generated power supply outage in Derna and Al Baydā. About 5 km2 in Derna, and 4 km2 in Al Baydā became darker based on comparison of SDGSAT-1 images acquired before and after the floods. River delta area in Derna city lost the majority of night-time light, with power supply not fully restored as of 17 September 2023. In Al Baydā, power supply has been almost fully restored as of 17 September 2023. Continuous observations have been planned for full assessment of power recovery.

**UNOSAT code FL20230912LBY, GDACS Id: 1102204** This map illustrates satellite-detected flood extent in the Al Tamimi Town, East Province (Libya) as observed from a Pléiades imagery acquired on 13 September 2023 at 11:15 local time after the passage of the Mediterranean tropical-like cyclone Daniel. Within the extent of the map, at least 64 structures appear to have been potentially exposed to rushing floodwaters. 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).

**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.

**UNOSAT code FL20230912LBY, GDACS Id: 1102204** This map illustrates satellite-detected flood impact in the 2 Derna dams over Benghazi Governorate, East pronvce, Libya, as observed from optical very-high resolution satellite imagery. Dam wall reservoirs appears to be destroyed in both the upstream and the downstream Derna dams. 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).

**UNOSAT code FL20230912LBY, GDACS Id: 1102204** Status: Power outage observed. Further action(s): continue monitoring Compared with Derna and Al Bayda, power supply of Benghazi was less affected by the floods. No significant power outage could be observed in Benghazi. Only a few areas  east of the city of Benghazi suffered of power outage after the floods, in which the power supply has recovered to pre-floods level on 24 September 2023.

**UNOSAT code FL20230912LBY, GDACS Id: 1102204** This map illustrates satellite-detected flood extent in Derna City located in the East Province of Libya, as observed from a Pléiades imagery acquired on 13 September 2023 at 13:39 local time after the passage of the Mediterranean tropical-like cyclone Daniel. Within the city of Derna, at least 2,217 buildings appear to have been exposed to rushing floodwaters. 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).

**UNOSAT code FL20230912LBY, GDACS Id: 1102204** This map illustrates satellite-detected flood extent in the centre of Derna (Libya) as observed from a Pléiades imagery acquired on 13 September 2023 at 13:39 local time after the passage of the Mediterranean tropical-like cyclone Daniel. Extensive damage and destructions are observed in the city centre and the port area. 2217 buildings were affected by the rushing floodwaters in Derna and 886 in this sector of the city. 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).
