Meta-Synthesis Pattern of Analysis and Assessment of Earthquake Disaster System

Earthquake disasters are typical giant open complex systems. In this article, the system analyzes the structure features from its framework, motion, and space-time. Its entirety characteristics' such as open, complexity, high dimension, uncertainty and emergence, are discussed. Based on the discussion of the earthquake disaster system's components, elements and influencing factors, the Hall for Workshop of Meta-synthetic Engineering, which is composed of a specialist system, a machine system, and a knowledge system, is constructed to analyze earthquake disaster, and then designs the meta-synthesis analyzing processes, with the following steps: starting from experts' experience and data statistics to obtain perceptual cognition, after that, building models to reach rational cognition, and then, re-practicing through computer operation, eventually, via experts' assessment, data processing, and the modifying model to achieve goals on recognition. Based on the analysis and assessment of well-known earthquakes, earthquake risk, bearing capacity of region disaster, essential information of earthquake, scope of disaster influencing, geological environmental security, carrying capacity of resource environmental, economical influence, social influence, and the benefit of disaster reduction are found to be the essential contents of assessment of earthquake disaster. The framework of the meta-synthesis assessment of earthquake disaster systems and the “men, machine, methods, techniques, data” based on meta-synthesis assessment system are constructed.
