Abstract

In recent years, unconventional emergencies have occurred frequently in China, which have seriously threatened people’s life and property safety. It is beneficial to analyze the scenario evolution of unconventional emergencies to grasp the focus of emergency management. In this paper, a questionnaire survey was conducted on a factory in the “5.12 Wenchuan Earthquake”, and the accident was divided into four scenarios: ten minutes before the earthquake, during the earthquake and the escape process, the local self-rescue process, and the external rescue process. Social Network Analysis method is used to explore the scenario evolution law of unconventional emergencies, and relevant suggestions are made in combination with the rules.
