Introduction: To cope with natural and unnatural critical events such as air crashes, car accidents, chemicals and earthquakes or floods needs powerful resource management. Some of these critical events are tiny and by using local and available resources management could be resolved, but some cover extended geographical areas and so need a massive, vast resources and high level management for example intense earthquakes which were occurred in Iran. Distributed information systems including web based DMS and DSS, that has been just developed in some countries, have gained much importance. One typical case was implemented by World Red Crescent in Turkey's earthquake which tolerated many damages six years ago.This system is a distributed system and a type of decision support system that can be used in vast critical by disaster managers. This system is compounded of operational research (for example mathematical based-optimization and simulation) and artificial intelligent (for example knowledge based-systems and pattern recognition) and information management systems (network and .Net based system) methods. Designing and implementing of this system is very important according to span discussion and available facilities in our country.

Literature review: This is a librarian and internet based-research. Architecture of disaster information management system based available information in various articles and web sites in internet are reviewed and then it has been naturalized based on conditions and facilities of our country.

Conclusion: In this research proposed architecture has benefits of similar systems as well as It has been naturalized based on conditions and available facilities and it can been operated in various organizations, and can reduce damages due to natural hazards. Applying this architecture is first step in triggering of natural disaster information management systems to reduce damages. Damages due to natural disasters should be reduced by using this system and integrating of available information of various resources in different organizations.
