An event causing significant damage, loss of life, or environmental degradation directly and principally resulting from human actions or inactions. These events starkly contrast with natural calamities, stemming not from uncontrollable forces of nature, but from failures in planning, safety protocols, technological management, or deliberate intent. Examples include industrial accidents like chemical spills, structural collapses due to engineering flaws, or large-scale pollution incidents caused by negligence.
Understanding the origins and characteristics of these incidents is vital for prevention and mitigation. Analyzing past events allows for the identification of systemic weaknesses and the implementation of improved safety measures. Furthermore, a clear understanding facilitates more effective emergency response, resource allocation, and legal accountability, ultimately contributing to a safer and more resilient society. Historically, focusing on these events has driven improvements in regulatory frameworks and ethical considerations within various industries.
