Özet:

Disasters are one of the biggest problems of the 21st century. Since disasters are seen as a structure that must be dealt with all over the world, many models/cycles have been put forward for its solution. The generally accepted main cycle is; risk and damage reduction, preparedness, response, recovery and reconstruction. The terms used in this cycle express what needs to be done before, during and after the disaster, but studies on which term is prioritized and why or where it should/should be included in the terminology are insufficient. Therefore, the aim of the study is to define the terms with their origins and definitions: "risk, risk assessment, hazard, threat, exposure, vulnerability, reduction, prevention, preparedness, risk management, disaster, catastrophe, response, recovery, crisis management”. The aim is to clearly reveal the etymological and semiological relationship between the terms and at what stage they should be used by examining them together. The Turkish origins of the terms to be examined were taken from Etimology Turkish, Nişanyan Sözlük, English origins from Online Etymology Dictionary and Merrıam-Webster. AFAD and UNDRR dictionaries have been taken as the basis for the definitions of terms, and many sources have been used for other definitions of meaning in the international literature. As a result of the study, it has been revealed that the origins of the terms in the disaster cycle and their meanings used today overlap.
