Analyzing economic impacts of disasters has attracted interest from a wide audience in recent years, not only because of the frequent occurrence of large natural disasters worldwide but also because of the spread of terrorism to a global scale. This paper reviews past modeling studies for economic impact analysis of disasters, focusing especially on the input-output model and related modeling frameworks, such as the social accounting matrix and the computable general equilibrium model. The paper also discusses the issues of disaster modeling raised by the literature, and proposes some future directions.Impact analysis, disasters, input-output, extensions,

Economic modeling issues for measuring damages and losses from disasters and their impacts are complex. The questions surrounding the potential economic effects of a disaster have been studied and discussed in various aspects. Input‐output analysis has been employed in many studies to measure and evaluate the economic impacts of disasters, mainly because of the ability to reflect the structure of regional economy in great detail. Whereas they provide useful information regarding the economic impacts and consequences and about the resource allocation strategies to minimize the losses and impacts, many of these studies have failed to investigate the dynamic nature of impact path over space and time, due to the difficulties to obtain such data and also to the static nature of input‐output framework. In order to analyze the spatial impacts of a disaster, Miyazawa's extension to the conventional input‐output framework is employed and is applied for the case of the Great Hanshin Earthquake.
