This paper provides an account of how the Global Earth Observation Catastrophe Assessment Network (GEO-CAN) was formed to facilitate a rapid damage assessment after the 12 January 2010 Haiti earthquake. GEO-CAN emerged from the theory of crowdsourcing and remote sensing-based damage interpretation and represents a new paradigm in post-disaster damage assessment. The GEO-CAN community, working with the World Bank (WB), the United Nation Institute for Training and Research (UNITAR) Operational Satellite Applications Programme (UNOSAT) and the European Commission's Joint Research Centre (JRC) led the way for a rapid Post Disaster Needs Assessment (PDNA) utilizing remote-sensing based analysis as the primary source of information for building damage. The results of the GEO-CAN damage assessment were incorporated into the final PDNA framework developed by the WB-UNOSAT-JRC and adopted by the Haitian government. The GEO-CAN initiative provides valuable lessons on multi-agency collaboration, rapid and implementable damage assessment protocols under extreme situations for the disaster management profession, developmental organizations, and society.
This report examines the problem of communicating emergency information to communities which are multi-ethnic. A probability sample of flood evacuation warning recipients (n=200) was taken from a small Western United States town with a large segment of Mexican-American citizens. Analyses of these data revealed three primary differentials by ethnicity: (1) Mexican-Americans were more sceptical than whites about believing warning messages, no matter how specific the message; (2) Mexican-Americans interpreted the same warning messages as indicating lower levels of personal danger; and (3) Mexican-Americans were less likely to under take a protective action (that is, evacuate) than whites. These findings suggest that there is a need for studies which explore the warning response decision-making process used by minorities, examine the criteria on which minorities interpret warning message content, and review the ways in which minorities evaluate the validity and accuracy of any given message.
SUMMARY This review of incentives to evacuate is meaningful largely in the context of planning for and managing the consequences of the impact of riverine floods. Of course, incentives do not constitute an emergency plan. At best, they should be seen as suggestions for structuring some elements of a plan. Furthermore, the enumeration of incentives presented here is meant to be suggestive rather than exhaustive. A primary objective of this paper has been to underscore the importance of advance planning in coping with hazards and to argue that, even though limited, existing research can be productively used in the planning process. The incentives described here are based upon or drawn from empirical research on people's performance under flood disaster conditions. This reflects the view that it is important to build emergency planning around people's known reaction patterns. Too often emergency plans which are administratively devised turn out to be based upon misconceptions of how people react (cf. Drabek and Stephenson, 1971, p. 202; Dynes et al., 1972, p. 31) and, therefore, potentially create more difficulties than they solve. One must be cautioned, however, that although our data indicate that people say they would support the idea of various evacuation incentives examined here, these are attitudinal data and not performance data. Thus, the real test of evacuation incentives lies in their implementation and in evaluation data on pilot programs which, unfortunately, do not presently exist. The outlook for the feasibility of developing and utilizing evacuation incentives appears to be positive, though, judging from responses to our interviews. In the final analysis, it would appear to be wise to develop emergency plans which guide and channel citizen actions into complementary and productive protection behavior patterns. The present discussion of incentives to evacuate is intended to encourage data‐based emergency planning.
Recent earthquakes have caused unacceptably high death tolls. We, the editors of the World Housing Encyclopedia, believe that reducing such an unacceptably high loss of life from earthquakes is the most important challenge facing the global earthquake engineering community. This paper acknowledges the continuing disparity between life loss from earthquakes in developing and developed countries, and the increasing vulnerability in developing countries. A sampling of current efforts to improve construction practices includes the publication of earthquake tips in India, construction manuals in Colombia, and the formation of various international networks to promote collaboration and information sharing. Future possibilities include more rewards for research into inadequately engineered construction, greater emphasis on small-scale, local efforts, and a stronger emphasis on advocacy. We believe that all of us, as earthquake professionals, have a responsibility to make the built environment safer worldwide.
