Post-earthquake damage assessment

Definition

Post-earthquake damage assessment refers to the systematic evaluation of structural integrity and safety of buildings and infrastructure following an earthquake event. This process involves inspecting, documenting, and analyzing damages to determine the extent of structural issues and the necessary interventions for repairs or retrofits. The assessment is crucial for ensuring public safety and informs decisions regarding evacuation, repair priorities, and future seismic design improvements.
