Short summary
This paper presents a completely new method based on a new data analysis technique (ALIF) to determine both the environmental and instrumental backgrounds applied to all the DEMETER satellite electric and magnetic field data over L'Aquila's seismic region. Interestingly, on 4 April 2009, when DEMETER flew exactly over L'Aquila at 20:29 UT, an anomalous signal was observed at 333 Hz on both the electric and magnetic field data, whose characteristics seem to be related to pre-seismic activity.
