An automated-electrical resistivity tomography (A-ERT) with repeated measurements at 4-hour intervals was installed in the vicinity of air and ground temperature boreholes in the Crater Lake site at Deception Island in 2010 in order to study the dynamics of the active layer. All apparent resistivity raw data, collected during one year, were analyzed regarding daily and monthly resistivity changes and then compared to the spatiotemporal temperature variability. Preliminary investigation of apparent resistivity data reveals that the thawing and freezing sequences of the active layer can be well identified using the installed A-ERT monitoring system.
