CBRN-p Hazards and Risks Triggered by Natural Events; Turkey Example

Due to its geostrategic location and global climate change, natural events have been experienced more frequently and severely in the last 10 years in our country. The probability of large-scale Chemical, Biological, Radiological, Nuclear and Explosive (CBRN-p) disasters that may occur with sequential effects, triggered by natural events, is generally low. However, the potential impacts on people, the environment, infrastructure, the economy of certain areas or the entire region/country are high. There are maps for natural events such as earthquakes, floods, landslides and avalanches in our country. However, there are no maps prepared for CBRN-p hazards. Considering that climate change increases the frequency and intensity of natural hazards related to weather, it is thought that knowing the inventory of hazards that may arise from existing CBRN-p substances can play a key role in reducing risks and preventing possible disasters. In our study, the concept of sequential disaster and CBRN-p hazards and risks that may arise from sequential disasters are discussed. In addition, maps containing industries and energy facilities in provinces where CBRN-p events are likely to occur, T.C. The earthquake, flood/flood, landslide and avalanche hazard maps created by the Ministry of Interior Disaster and Emergency Management Presidency (AFAD) were prepared by overlapping, and the risks that may arise as a result of sequential effects were evaluated based on the literature review. As a result of this evaluation, the interdependence of natural events and CBRN-p events; It has been revealed that critical steps such as reducing vulnerabilities, increasing resilience, assessing secondary disasters and risk reduction practices in critical infrastructures should be addressed, and the risks posed by mutually interacting, combined, interconnected and sequential hazards should not be ignored when making risk assessments. It is expected that our study will contribute to the literature in preventing CBRN-p events, which may be triggered by natural events in our country, from turning into sequential disasters, and will guide the preparation of CBRN-p hazard and risk maps.
