Are we under threat when we risk? Notions and terminology of risk theory due to geological hazard

Well explained terminology in the field of natural and other disasters makes possible qualitative professional discussion and full exchange of knowledge between different professionals in this interdisciplinary field. From literature we extract definitions of terms hazard, risk and disaster. Additionally, we show also the detailed meaning of a sequence of other relevant terms in the field of risk management such as vulnerability and specific risk. Unified use of the conceptual and terminological sequence “hazard-specific riskrisk” is suggested.
