Abstract: Research in emergency response systems has produced significant literature in a very short span of time. We review a corpus of published works on how Information Communication Technology (ICT) is being utilized and the type of tasks ICT attempts to support in the event of a crisis due to disasters, whether natural or man-made. In our research, we have been able to distinguish eight types of tasks supported by technology during a disaster. We list some of these technologies used by the public, practitioners and researchers to illustrate the current trends of technology usage. We also identify gaps and technology needs that require our attention. Given the increasing frequency and severity of disasters, this research is timely as it (1) contributes to our understanding of the trends of development and technology use during times of crises and (2) identifies potential areas for future work to improve ICT's role during times of emergency.
