Earthquake Early Warning Systems

Opis

Seismic early warning is being recognized as a methodology which offers the biggest potential for real time seismic risk mitigation, particularly in towns and industrial areas. In order to be effectively applied it requires close cooperation between seismologists, communication experts and seismic engineers. The added value of this book is to offer an overview of frontier problems related to all aspects of the seismic early warning chain, from basic seismological issues to engineering problems and system reliability. Early warning seismic networks also provide near real time shake maps for damage estimation and emergency management immediately after an event. The state of the major early warning systems in operation and in the course of development (e.g. those operated in Japan, Taiwan, Rumania, Turkey and those being implemented in California and Southern Italy) is also presented. It is the first time that all these aspects are specifically focused upon within a single book. It will constitute a reference not only for researchers and students, but for all institutions which are willing to face the development and/or implementation of this methodology, including International organizations (UNDP, European Civil Protection, European Commision) National Civil Defence organizations, industry and town-planners.

During the past few decades, economic losses and human casualties due to natural disasters increased exponentially on our planet, mainly because of the increased density of population and industry in high hazard areas. Although the prediction of earthquakes is not practicable yet, the present technology allows a prompt identification of the onset of any dangerous seismic event before it hits an urban area. Earthquake early warning can provide an alert within a few tens of seconds in advance. This small lead time may be used to minimize property damage and loss of lives in metropolitan areas and to aid emergency response. The book provides information on the major EEW systems in operation and on the state of the art of the different blocks forming an EW system: the rapid detection and estimation of the earthquake’s focal parameters, the signal transmission, the engineering interface and the information reliability/false alarm problem.
