Geoelectric variations related to earthquakes observed during a 3-year independent investigation

We present observations of the geoelectric field prior to some earthquakes. The data were collected during a three year (1992–1994) independent experimental investigation of VAN at the University of Patras Seismological Center. The recorded signals were: a) Gradual Variations of the Electric Field (...

Zusammenfassung:	We present observations of the geoelectric field prior to some earthquakes. The data were collected during a three year (1992–1994) independent experimental investigation of VAN at the University of Patras Seismological Center. The recorded signals were: a) Gradual Variations of the Electric Field (GVEF), b) Periodic Variation of the Electric Field (PVEF), and c) Seismic Electric Signals (SES).
