The purpose of this study is to evaluate how the participants’ awareness of disaster prevention, such as disaster risk perception and disaster prevention behavioral intention, improve when they experience the VR disaster in a familiar environment like their own room. In the experiment, participants were asked to take pictures of the environment in which the participant spend their daily lives and to experience virtual earthquake and fire in the familiar environment created from the pictures and in the non-familiar environment. After experiencing each disaster experience environment, participants were asked to answer a questionnaire about their awareness of disaster prevention, which included a sense of reality, a sense of fear, a sense of familiar environment, communication intention, disaster risk perception, anxiety and disaster prevention behavioral intention to compare the effects of each disaster experience environment on the awareness of disaster prevention. In the results, it was found that experiencing VR disaster in a familiar environment may trigger people to imagine that disaster may actually happen to them, and may increase their awareness of disaster prevention. However, it was also suggested the possibility that people are more likely to notice unnatural places in the experience because they usually see the environment repeatedly.
