Decreased integrity, size, efficiency (function), or conditions that are not considered beneficial by a community as a result of an adverse event. Depending on the application, damage can be measured in different ways, using metrics appropriate for each type of risk analysis. In particular, non-physical damage affects the social life of an urban system. This type of damage is understood as a measure of social disruption, in terms of deterioration of social relations and functions, that a natural or anthropogenic event causes to a community in the short to medium term (i.e. homelessness) or psychological symptoms in a part of the population, such as anxiety, panic syndrome, correlated with the possibility of new occurrence of the risk events.
