Podsumowanie	The Protective Action Decision Model (PADM), developed by Michael Lindell and Ronald Perry, is a multistage behavioral framework explaining how people at risk decide whether and how to protect themselves when warned of an environmental hazard. Synthesizing decades of disaster warning-response research, PADM traces a chain from environmental and social cues and warning messages, through predecisional processes of exposure, attention, and comprehension, to three core perceptions — of the threat, of the candidate protective actions, and of the social stakeholders involved. These perceptions drive a structured decision sequence — identifying the risk, assessing it, searching for and evaluating protective actions, and selecting a response — that, together with situational facilitators and impediments, determines the behavioral outcome. The 2012 statement refined the model and connected it to applications including risk communication design, hazard-adjustment adoption, and evacuation modeling.	The Pressure and Release model (PAR), developed by Ben Wisner, Piers Blaikie, Terry Cannon, and Ian Davis in their book At Risk, is the foundational framework for analyzing disasters as socially produced rather than purely natural events. It conceptualizes a disaster as the intersection of two opposing forces: a natural hazard on one side and, on the other, a progression of vulnerability that builds from deep root causes through dynamic pressures into concrete unsafe conditions. The metaphor is a nutcracker or 'crunch': the hazard squeezes a population whose vulnerability has been progressively constructed by political, economic, and social processes. Risk is expressed as the product of hazard and vulnerability, and the model's hopeful corollary — the 'release' — is that reducing risk means tracing the chain backward and relieving the pressures, addressing unsafe conditions, dynamic pressures, and ultimately root causes.
