Massenedfall

Massenedfall is a term used in theoretical risk studies to describe rapid, self-reinforcing cascades that cause large-scale failures across interconnected social-technical systems. It denotes a phenomenon where initial disturbances propagate through feedback loops between human behavior and infrastructure, producing a sudden shift from normal operation to widespread disruption.

The word combines elements implying mass and collapse, reflecting its emphasis on mass-scale cascading effects. The term is not widely standardized and appears mainly in speculative or preliminary literature on systemic risk and disaster dynamics.

Key mechanisms include information cascades, demand surges, network dependencies, and adaptive responses that amplify stress. Triggers can be outages, rumors, or localized shocks; once a threshold is crossed, avalanches of failures propagate through transport, energy, communications, and financial networks, often more rapidly than traditional risk models predict.

Applications of the concept appear in urban resilience, crisis management, and financial stability research. For example, a massenedfall might describe simultaneous IT outages and supply chain interruptions in a city during severe weather, leading to a rapid collapse of services, or a rapid market sell-off triggered by a rumor and reinforced by automated trading.

Scholars debate the usefulness and definitional boundaries of massenedfall, arguing that it overlaps with established concepts such as cascading failure, systemic risk, and panicked diffusion. It remains a niche term with limited empirical validation.
