UNOSAT Gaza City Structural Damage Assessment from September 2025

83% of all structures in Gaza City were damaged according to satellite imagery analysis from 22–23 September 2025. The United Nations Satellite Centre (UNOSAT) identified 41,221 affected structures, including 17,734 destroyed and 4,345 severely damaged, representing a 7% increase in total affected structures since July 2025. This preliminary analysis estimates damage to 81,159 housing units, potentially affecting approximately 467,523 displaced persons.

Use Cases

• Track damage progression over time based on the comparison between imagery from July and September 2025.
• Prioritize humanitarian response based on the concentration of destroyed and severely damaged structures in specific neighborhoods like Az Zaitoun.
• Estimate displacement and housing needs based on the reported number of damaged housing units and affected persons.
• Validate field reports with satellite-derived damage classifications (destroyed, severely damaged, moderately damaged, possibly damaged).

Strengths

• Analysis is based on specific satellite imagery collected on 22–23 September 2025.
• Provides quantified counts for four distinct damage categories, totaling 41,221 affected structures.
• Includes a temporal comparison showing a 36% increase in destroyed structures since a prior assessment.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The analysis is described as preliminary and has not yet been validated in the field.
