Abstract

A pattern recognition based approach is used in this study to examine single-channel Long Term Geoelectric Potential difference (LTGP) data recorded during the 1998-2003 period in Western Greece. Seeking a schema that automatically discovers data features containing information possibly related to seismic activity, patterns in LTGP data recorded during small (72-hour) consecutive time segments are examined, and pattern recognition methods are used to link them to seismic information of co-occurring seismic events, such as epicenter and depth.
