Remote Sensing Structural Damage Assessment

This report or any part of it should not be reproduced in any form without the wrien permission of Miyamoto Internaonal, Inc. EXECUTIVE SUMMARY The technical bullen presented in this report provides an esmate of the structural damage and shelter needs in the Gaza Strip based on remote sensing data. The report describes the apparent levels of damage in mulple cies, along with a summary of the common building typologies across the area. Color-coded damage maps outline the areas and levels of damage across the region, while pie charts provide a breakdown of probable damage severity. A range of publicly available open-source data, such as UNOSAT, OpenStreetMap, and LandScan Global, were used in this assessment report. The damage results are produced using UNOSAT data dated April 1, 2024. At that slice in me, more than 50% of the Gaza Strip had been affected, with around 34,000 structures destroyed, 17,000 severely damaged, and 43,000 moderately damaged. Approximately 78% of all buildings in North Gaza were damaged to varying degrees, including moderate, severe, or destroyed, with moderately damaged structures accounng for about 30% of all damaged structures. Similarly, 67% of the building stock in Gaza appears to have sustained varying levels of damage. At the me of wring this report, the situaon in the Gaza Strip has now expanded significantly to the south, resulng in significantly more damage since the last UNOSAT dataset release. It is observed that many of the southern areas of the Strip, such as Khan Younis, Deir Al-Balah, and Rafah, now have suffered a similar level of damage as the north. Approximately 72% of the buildings in Khan Younis and 27% of the buildings in Deir Al-Balah appear to have sustained various levels of damage. As the conflict is progressing further south, approximately 10% of the buildings in Rafah are esmated to have different levels of damage. There are nearly 180,000 structures across the enrety of the Gaza Strip. If damage levels are similar then it is likely that more than 50% of buildings, approximately 1,10,000 structures that are mainly residenal, are likely to be damaged and now uninhabitable across the enre area. As a result, approximately 1.2 million people are likely to be without adequate safe housing and in urgent need of emergency shelter and housing recovery assistance. Many more people from non-damaged structures are also likely to be temporarily displaced through fear and lack of adequate services. The UN Shelter Cluster reports 1.9 million internally displaced persons (IDPs) in Gaza, nearly 85% of the populaon. Housing recovery and reconstrucon efforts in Ukraine and other recent global disasters have shown that once safe access is available, rapid repairs to light to moderately damaged structures can be one of the fastest, most cost-effecve, and most dignified ways to address the emergency shelter needs of the affected populaon. Rapid emergency repairs can also help kick-start early recovery, ensuring a more rapid transion to a permanent, durable soluon for those who have been displaced.
