Introduction Disasters provoked by the natural forces or the technical activities of people became a distinctive feature of the 20th and the 21st centuries and a major cause the mass traumatism among the population. In the common sense of the term, disaster is considered an unexpected destructive change followed by the significant disruptions and death of the people involved in the given situation. The researchers suggest distinguishing several types of disasters: natural, technogenic, and social (Lindell, 2013). And despite the differences in the origins of diverse disasters, they have the common features of abruptness, a serious threat to health and welfare of individuals and communities, interference with a regular mode of life, and violation of the environmental conditions’ integrity. Human Behavior: Disaster Disruption and Adjustment Along with the apparent negative impact on physical well-being, disasters affect the psychological state and human behavior. During the initial period of disaster unfolding, human behavior is usually determined by an intensive emotion of fear which mobilizes the organism for life-saving activities. Fear activation affects motor activity – the effect can vary from the increase in physical activity to the complete termination of motion – and decrease in decision-making capabilities (Duo, Shen, Zhao, & Gong, 2016). In crisis situations, only a few people can maintain composure and evaluate the alternatives for actions, while the majority of people become overwhelmed for several minutes. Within a few days after exposure to a traumatic experience, the victim comprehends the tragedy, and this initial post-traumatic stage is associated with a high level of stress and psychological instability. At this stage, a person may feel an acute aggravation of physical and mental conditions. At this stage panic attacks, the decrease in moral behavioral norms, depression, loss of appetite, and motivation for activity may occur. The stage of psychological adjustment usually commences in two weeks after exposure to the impacts of a disaster, and it is manifested in behavioral reactions such as the resumption to interpersonal communication, normalization of emotional state, and mental condition. Factors Influencing Response to Disasters According to Lindell (2013), exposure to disasters may cause a great variety of adverse psychological responses, and the character of the psychological impact significantly depends on the type of disaster, its location, and the demographic background of the victim’s personality. It is considered that the condition of time may significantly affect victims’ behavior as well. For example, the analysis of the Titanic and the Lusitania disaster demonstrated that when the events unfold rapidly, the individuals become driven by the vital instincts which highlight individual egoistic concerns (Frey, Savage, & Torgler, 2011). On the contrary, when the situation develops slowly, people tend to demonstrate altruism, compliance with social norms, and personal values. The common post-disaster effects include the changes in family bonding (both positive and negative), social and psychological maladaptation, changes in risk perception, excess stress, depression, and other psychological conditions influencing individual behavior.
