The invention discloses an earthquake disaster risk assessment and countermeasure analysis system. The system starts from five aspects of earthquake disaster risk investigation management, earthquakedisaster risk assessment, earthquake disaster loss pre-assessment, earthquake disaster risk treatment auxiliary decision and earthquake disaster risk assessment public service. The whole process frominvestigation, evaluation to governance of the earthquake disaster risk is covered, and a scientific technical platform is provided for improving the earthquake disaster risk evaluation and governancecapacity. The formation of a key technical system for earthquake disaster risk prevention in China is effectively promoted, and a scientific and technological application technology for reducing earthquake disaster risks is promoted. Scientific basis can be provided for government to carry out earthquake disaster risk prevention and control and the like, and the earthquake disaster risk prevention capacity is effectively improved, so normal disaster reduction is achieved, and the earthquake disaster risk is effectively reduced. Important engineering such as national energy development strategies, economic development strategies and the like, social and economic development and life and property safety of people are guaranteed, and important actual quakeproof and disaster reduction significance is achieved.
