The procedure for the measurements: The telemetric VAN network and how the epicenter and magnitude are predicted
The experimental procedure to measure a preseismic VAN signal, or SES, is simply the following: Two electrodes are driven into the earth, to a depth of, for example, two meters. Each electrode is connected to one end of an insulated cable and then the potential difference is measured between the two free ends of the wires with a voltmeter (which in practice is a differential amplifier).
