An overview on disasters

Abstract

PurposeThis paper seeks to provide graduate students, researchers, and government and independent agencies with an overview of disasters.Design/methodology/approachDisasters have been the subject of research and a source of concern to academicians and government and independent agencies. In this paper disaster types are collected from several sources such as technical, general articles, internet web sites, and internal reports. Disaster types, definitions, hazards and mitigations are reviewed. Disasters are classified into natural disasters, man‐made disasters, and hybrid disasters. Man‐made disasters are classified into technological disasters, transportation accidents, public places failure, and production failure. Natural and/or man‐made disasters sometimes lead to subsequent disasters.FindingsDisasters are classified into three types: natural, man‐made, and hybrid disasters. It is believed that the three disaster types cover all disastrous events. Disasters have different characteristics and impacts; however, disasters have a common element, which is their severity. Natural disasters are those disasters that result from natural forces. Man‐made disasters are those disasters that result from human decisions. Hybrid disasters are those disasters that result from both natural and man‐made causes. Subsequent disasters are those disasters that result from natural and/or man‐made disasters. Epidemics could be a disaster or a subsequent disaster.Originality/valueThis paper presents the types, definition, hazards, and mitigation of disasters. Disasters are arranged into disaster types, sub‐disasters, and disastrous events in the form of a disaster tree. An algorithm can be written utilizing this disaster tree. The algorithm can be used for training purposes to prevent or reduce disasters.
