Electrotelluric noise minimization for seismoelectric effect detection

Boris Shirman, Avi Shapira

Research output: Contribution to journalArticlepeer-review


Three electrotelluric stations were installed in Israel in order to examine electric field changes associated with earthquake occurrence at the Bar-Giora observatory, at the Ein Gedi field school and on Mt. Tur'an. During the observation period 1994-1995, no earthquake was shown to cause any changes in the electric field at the measurement sites. This study focused on signal processing of electric field continuous measurements. The main purpose was to identify, and consequently filter out, signals caused by local and extra-terrestrial sources. New procedures for data processing were developed mainly using data from the Bar-Giora station, which has been instrumental in the experiments.
