Abstract
Natural hazard-triggered technological (Natech) accidents occur when events like landslides, floods, and storms damage industrial infrastructure, causing cascading failures. These failures can release hazardous substances and energy, posing serious risks to human safety, the environment, and economic stability. The 2011 Fukushima disaster exemplifies the severe consequences of Natech accidents, where tsunami-induced flooding led to a nuclear accident. As natural hazards and extreme weather events increase, understanding and mitigating Natech risks is critical for civil security. The NTNU Natech research group advances knowledge through interdisciplinary approaches, focusing on risk assessment, resilience strategies, and proactive mitigation solutions.
