Disaster Risk Assessment of North Bulgarian Black Sea Coast

The methodology of comprehensive risk assessment for natural disasters has been the subject of recent research. The risk assessment process is thoroughly explained and applied to geological hazards (such as landslides, earthquakes, and tsunamis) that have a potential for calamity. Obtaining a complicated risk level for a few geophysical and geological risks in northeast Bulgaria is the major goal. It has been done to clearly identify the many dangers, their effects, the elements at risk, exposure, and vulnerability, as well as to analyze the secondary events that were generated. For the first time in practice, a thorough risk assessment approach is used, and it incorporates the idea of risk perception. The methodology’s adaptability enables the presentation of the results as either a risk matrix or a risk profile. It depends on the tasks, challenges, and scientific puzzles that need to be solved as well as expert judgment. The outcome showed strong practical applicability and sustainability.
