摘要
Since 1983, continuous monitoring of the electrotelluric field has been carried out using an array of measuring stations located at various sites in Greece. The basic physical properties of the transient changes-seismic electric signals (SES)-in the electrotelluric field that are forerunners of earthquakes were first described six years ago. Since then a large body of data has been collected resulting in new insight into various aspects of the method. The present paper reviews the latest developments in SES-based earthquake prediction and describes the current procedures used to predict the epicenter and magnitude of an impending earthquake. A detailed list of the predictions officially issued in Greece during the past 3 years (January 1, 1987-November 30, 1989) is also given. Public warnings were issued well before the most destructive seismic activity.
