Managing Earthquake Debris: Environmental Issues, Health Impacts, and Risk Reduction Measures

Abstract

Earthquakes have the potential to cause severe and widespread structural damage to buildings and infrastructure in the affected area. Earthquake debris mainly results from building collapses during intense ground motion and the emergency demolition of damaged and unstable buildings following a devastating earthquake. Debris management constitutes a major challenge that must be met by all those participating in disaster management as it poses threats to both the natural environment and public health in an earthquake-affected area. This narrative review examines the hazards that arise throughout the early phases of debris removal, when personnel operate in disaster-affected areas, to the last steps of sorting and disposal. Furthermore, emphasis is also given to the environmental impact caused by unregulated debris disposal on natural habitats that are highly sensitive and susceptible to hazardous substances and materials found in the debris. In the same framework, measures are proposed for alleviating the negative impacts of debris management on the well-being of all individuals involved, including workers, volunteers, and the local community, as well as the surrounding natural environment, encompassing soil, surface and groundwater, as well as air quality.
