2023 Syria Earthquake – Preliminary Debris Quantification and Optioneering for selected sites in Aleppo

This initial quantification of earthquake generated debris selected towns and villages in Aleppo is derived from building footprint data and damage assessments from Microsoft. This data was combined with an above surface height model, derived from the difference between a Digital Terrain Model (SRTM) and a Digital Surface Model (ALOS World 3D). For visualization and modelling purposes, results were aggregated into an rectangular grid. Two scenarios have been developed: Scenario 1: 100% of debris is disposed of at disposal facilities. Scenario 2: 50% of debris is recycled at a centralized recycling facility and remaining 50% is disposed of. For modelling purposes, disposal and recycling facilities are assumed to be at a 10km distance from source of debris. Cost assumptions are based on local debris management costs provided by UNDP, and results will need to be refined based on local parameters.
