Cascades

Cascades are sequences of events where one action triggers another, creating a chain reaction. In natural or technological systems, a small change or disturbance can set off a series of linked effects. For example, in power grids, a minor failure might cause multiple other failures, leading to a widespread outage. Cascades help us understand how interconnected parts can lead to large-scale impacts, emphasizing the importance of managing initial risks to prevent domino-like failures in complex systems.
