However, few multi-hazard interrelations analysis frameworks can cope with both technological and natural hazards. As far as we know, only Wang et al. constructed a review of the research into the interrelations between hazards in which a broad framework is proposed to divide hazard interrelations between natural and technological hazards into 3 categories: mutually amplified hazards, mutually exclusive hazards, and non-influential hazards. Due to the special characteristics of CPI, the involved hazards are broad, which leads to a multi-disciplinary problem from natural (Meteorology, Physic, Geology, etc.) to technological (Hazardous materials, Facility, Reliability, etc.) and social (Economics, Management, Ergonomics, etc.) aspects .
