“National natural disaster assessment system be set up and perfected, risk assessment, emergency response assessment, loss assessment, social influence assessment and performance assessment be continuously enhanced, system for comprehensive assessment of major and catastrophic natural disaster be perfected, and scientificness, standardization and normalization of disaster assessment be raised.”
The National Plan for Disaster Prevention and Reduction (2011—2015)
The research and development of assessment technology system for major natural disaster situations and comprehensive risks is included as one of the major tasks.
Emphasis is laid on the development of qualitative assessment models for losses of major natural disasters, such as earthquakes and geological disasters, meteorological and oceanic disasters, etc., the speeding up of development of fast disaster assessment technology system integrating space technologies and models, and the development of system for comprehensive disaster risk analysis, simulation and policy-making support.
The 12th Five-year Special Plan for National Disaster Prevention and Reduction Science and Technology (2011—2015)
Formulate the working mechanism of disaster assessment
The Instruction of Enhancing Natural Disaster Relief Assessment, introduced by Ministry of Civil Affair in 2012, based on relief needs, is aimed to actively push the formulation of mechanism of natural disaster relief assessment, standardize assessment program, improve workflow, complete the indices system, explore working approaches.Assessment of natural disaster relief mainly includes 4 major categories, which are relief preparedness assessment, emergency relief assessment, post‐disaster relief assessment and annual comprehensive assessment, and 12 subcategories focusing on specific fields.

Major disaster risk and loss assessment
The objectives of loss assessment: Objectively and timely learn about the damages and economic losses
caused by disasters. Timely launch national and local emergency plans, and take emergency
relief measures. Formulate the plans for recovery and reconstruction.
