The risk posed by natural hazards to the technological systems is known as Natech risk. It is different from the more widely known and studied risk posed by such sites to the environment and society. Though currently, available risk assessment techniques recognize Natech, the specific qualitative technique for Natech risk assessment and reduction has not yet been developed. After analyzing past data of Natech accidents, relevant guide words have been suggested in this study. These guide words will help anticipate Natech risk and visualize the Natech scenario. Once the Natech risk is identified, corresponding risk reduction measures can be taken to avoid possible Natech accidents and consequences.

自然灾害对技术系统造成的风险称为 Natech 风险。它不同于更广为人知和研究过的此类场所对环境和社会造成的风险。尽管目前可用的风险评估技术认可 Natech，但尚未开发用于 Natech 风险评估和降低的特定定性技术。在分析了Natech事故的过往数据后，本研究提出了相关的引导词。这些指导词将有助于预测 Natech 风险和可视化 Natech 场景。一旦识别出Natech风险，就可以采取相应的风险降低措施，避免可能发生的Natech事故和后果。
