The United Nations University is an organ of the United Nations estab- lished by the General Assembly in 1972 to be an international community of scholars engaged in research, advanced training, and the dissemination of knowledge related to the pressing global problems of human survival, development, and welfare. Its activities focus mainly on the areas of peace and governance, environment and sustainable development, and science and technology in relation to human welfare. The University operates through a worldwide network of research and postgraduate training centres, with its planning and coordinating headquarters in Tokyo. The United Nations University Press, the publishing division of the UNU, publishes scholarly and policy-oriented books and periodicals in areas related to the University’s research.

A large debt of gratitude is owed to the United Nations University (Tokyo), especially in the persons of Roland Fuchs, former Vice Rector, who encouraged the project’s initial stages, and Juha Uitto, a young Finnish geographer who coordinated it. Members of the International Geo- graphical Union’s Study Group on the Disaster Vulnerability of Mega- cities also played a vital role. Several were participants in the 1994 Tokyo conference on which this book is based and later became founding members of the Study Group’s steering committee. Rutgers University graduate studentsenrolledinseminarsonnatural hazards during 1993, 1994, and 1996 deserve special mention. Many con- ducted their own case-studies of disaster-susceptible mega-cities, which helped to inform chapter 13. The following were particularly helpful: Roger Balm, Joe Center, Mike Craghan, Marla Emery, Ruth Gilmore, Jojo Hardoy, Ted Kilian, Lisa Lacourse, Juliana Maantay, Sudha Maheshwari, Elaine Matthews, Anastassia Mikhailova, Mariana Mossler, Karen Nichols, Karen Patterson, Lena Raberg, Bruce Ramsay, Karlene Samuels, Lisa Vandermark, and Doracie Zoleta-Nantes. Colleagues in a wide variety of organizations and venues served as audiences for early drafts and provided valuable inputs. These included: the Hazards Spe- cialty Group of the Association of American Geographers; the annual vii viii ACKNOWLEDGEMENTS Hazards Workshops of the Natural Hazards Research and Applications Information Center (Boulder, Colorado); a special session of the 1995 meeting of the Institute of British Geographers; the International Sym- posium on Urban Growth and Natural Hazards (Clermont-Ferrand, France), and the First International Earthquakes and Megacities Work- shop (Seeheim, Germany). Maria Steppanen and C. Emdad Haque were external readers of manuscripts, supplied background materials, and added helpful local details that have been incorporated into case-study chapters. Scott Campbell supplied a key background paper and thought-provoking com- ments. Mike Siegel of the Rutgers University Cartography Laboratory oversaw the preparation or redrawing of maps and illustrations. All of these, and many others, have tried to keep me from error. If I have committed few, theirs is the praise; otherwise the flaws are my own.
