A disaster subculture is a community’s preserved residue of learning about recurrent hazards, expressed in knowledge, norms, practices, and organizational expectations [@wengerweller1973; @anderson1965].
Within emergent disaster response, the term matters because communities do not always begin from improvisation alone. Repeated experience with a hazard can sediment local methods of warning, evacuation, mutual help, and repair that become available again when the hazard returns [@wengerweller1973].
A disaster subculture is not just memory. It is memory preserved as social practice. That preservation can live in stories, routines, organization, training, and shared expectations about what people are supposed to do when ordinary life is interrupted.
