The goal of this research was to offer theoretical knowledge by reviewing relevant research on crises and their impact on national security. Policymakers face many challenges in creating quality national security programs in order to make states and societies as resilient as possible to crises. An appropriate level of earthquake preparedness by critical infrastructure operators can only be established after a comprehensive risk assessment. Any discussion of earthquake protection must attempt to identify the distribution of vulnerability in any given society and region of the world. Vulnerability to earthquakes is largely concentrated in the poorer developing countries of the world. In such countries, it rarely makes sense to try to implement earthquake protection as an activity separate from other measures to improve the general living conditions of the most economically vulnerable groups. Likewise, there is evidence that even in the richest countries there is significant earthquake vulnerability among the poorest members of society, who are forced to live in old and flimsy buildings because it is the only accommodation they can afford. Methods of upgrading these buildings are becoming available and better understood.
