Weblogs (blogs) emerged in the late 1990s in the form of online diaries where individuals maintain accounts of their day-to-day experiences. However, the usefulness of weblogs in hazards research remains to be investigated. The purpose of this chapter is to reflect on the extent to which the current views portrayed in the literature, with regard to the effects of social vulnerability on disaster response, may be applied in the context of the Hurricane Katrina disaster as captured by weblogs. It is not to provide a comprehensive analysis of vulnerability and re-sponse following the disaster. Preliminary findings demonstrate some feelings of discrimination and inequalities were apparent but did not appear to be widespread. This suggests that, perhaps, issues such as gender equality and the needs of disadvantaged members are being adequately supported in certain contexts. The results also highlight the potential of new data sources such as weblogs for quick response research and how they may provide significant insights that complement or substitute traditional research methods that may not be feasible to conduct during the immediate aftermath period.
