"The time for a first book on Geoethics has come. The faster, greedier pace of society and globalization demands it. The comfortable life of scholars in the ivory tower is coming to a rude awakening. People demand understandable information on geo-hazards, judges condemn scientist and engineers for lack of communication, indigenous people rise in anger accusing experts of misleading them, attempts to avoid transparency in developments still exist, the helplessness of technology to deal with nuclear waste becomes more evident every day and nature exposes shortcuts in constructing critical facilities with her own awesome force. Less dramatic, but damaging the credibility of the scientific community is the rising number of cases of plagiarism, made easy by the electronic world of communication. In addition, the community of geoscientists needs to become aware of subtle ways in which our work can be useless for or even misleading the public"--

Earthquake Hazard, Risk and Disasters presents the latest scientific developments and reviews of research addressing seismic hazard and seismic risk, including causality rates, impacts on society, preparedness, insurance and mitigation. The current controversies in seismic hazard assessment and earthquake prediction are addressed from different points of view. Basic tools for understanding the seismic risk and to reduce it, like paleoseismology, remote sensing, and engineering are discussed. Contains contributions from expert seismologists, geologists, engineers and geophysicists selected by
