Abstract Measuring the sustainability of any hazard early warning system (EWS) requires interdisciplinary frameworks. What has often been termed as an EWS was not a system approach, but one of six models: chain, single cycle, multiple cycle, network, isolated, and combinations of them. This paper offers a more comprehensive framework with quantitative measurements for incentive structures of EWS such as governance and institutional indicators, knowledge society indicators, and economic and human development indicators extracted from World Bank's (2007) KAM database. It also proposes qualitative measures for assessing micro level EWSs using composite concepts of efficiency, effectiveness, equity and legitimacy.
