Current approaches of measuring vulnerability to natural hazards generally use a rather static perspective that focuses on a single point in time—often before a hazardous event occurs. In contrast, the paper argues that vulnerability assessment should also take into account the changing dynamics during and after a disaster. This paper provides a comparative analysis of the situation in Sri Lanka and Indonesia within the context of the 2004 Indian Ocean tsunami. The author presents concepts for measuring revealed vulnerabilities and methods of assessing the recovery process, and highlights the differing ways in which the tsunami affected the ongoing civil conflicts in both regions.
