摘要

Considering earthquakes, many areas of major urbanization(e.g., Tokyo, Istanbul, Naples, Mexico City) are exposed to significant seismic hazard. Currently, several parts of the world have some form of earthquake early warning system (EEWS)either in operation or under development (e.g., Taiwan: Wu and Teng 2002; Japan: Horiuchi et al. 2005; California: Wurman et al. 2007; Istanbul: Erdik et al. 2003; Bucharest: lonescu et al. 2007; Mexico City: Espinosa-Aranda et al. 1995). However, these systems usually involve the use of a relatively low number of sensors (from several to tens of units), a fact largely dictated by the high cost of such instrumentation. In addition, these systems must usually communicate their data to centralized processing and archiving facilities. An example of a standard centralized EEWS is the Istanbul Earthquake Rapid Response and Early Warning System (IERREWS; Erdik et al. 2003) operated by Kandilli Observatory and Earthquake Research Institute (KOERI) of Bogazici University (Figure 1A). This system is made up of 10 strong-motion stations that are installed as close as possible to the fault zone of the north Anatolian fault, which runs through the Marmara Sea to the south of Istanbul. In the IERREWS, a centralized philosophy of early warning is adopted, meaning that there is a continuous telemetry of data between IERREWS stations and the main data center, where the alarm is decided. Transmission is realized through the use of a digital spread spectrum radio modem system involving repeater stations.
