INTRODUCTION: Today, natural crises have become an inseparable reality of human life, and one of the key measures to prevent the destructive consequences of natural disasters in any region is the identification and zoning of natural hazards. Therefore, the purpose of this research is to identify the factors affecting the occurrence and zoning of natural hazards within Mehdishahr county, Semnan province.
METHODS: This research was conducted using a mixed method (quantitative and qualitative) and the status of risk and crisis management in Mehdishahr was examined. Data were collected from existing documents, interviews with key stakeholders (local officials, experts, and representatives of local communities), and analysis of statistical data related to past incidents. Using the Analytic Hierarchy Process (AHP) method, the factors under study were compared in pairs and the weight of each was calculated.
FINDINGS: According to the findings, floods have the greatest impact on the riverbed and distance from it, the river parameter with 0.335 plays more than one-third of the flood risk, and land use with 0.096 has the lowest sensitivity. Also, faults with 0.370 are considered the most important and land type with 0.087 is the least important factor in causing earthquakes. Based on the results obtained from the AHP model, human factors, especially roads and paths, have the greatest impact on the occurrence of landslides, and along rivers they account for one-third of the factors affecting the occurrence of landslides.
CONCLUSION: Considering the factors affecting the occurrence of natural disasters in Mehdishahr county, some preventive measures are necessary to preserve natural resources and the environment, ensure sustainable economic and social development, and reduce vulnerability, including: changing land use and respecting the privacy of rivers, preventing construction on the banks of rivers, stabilizing and stabilizing slopes, observing building regulations, and strengthening local capacities through education, empowerment, and promoting public and specialized awareness.
