Telluric currents have a number of origins caused by naturel events such as electrochemistry activities, atmospheric electricity, ionospheric conditions, solar activity and geomagnetism. Telluric currents circulate continuously in the upper regions of the earth's crust. Between 21 and 27 August 1991, ground based observations of the telluric currents were made at Boyali, Kastamonu (northwestern Turkey). During the continuous monitoring, the telluric (originated by Pc geomagnetic pulsations) and the other currents are simultaneously recorded chart paper. It is readily apparent that the persistent variations and the micropulsations have different patterns caused by high atmospheric electricity due to local lightning, and by the geomagnetic field of the Earth. additional examples from different sites recorded using a magneto-telluric measuring system are given.
