Abstract: On 6 April 2009 a seismic sequence culminated with the Mw6.3 main shock which heavily damaged the town of L’Aquila. Here, we report the analysis of ULF magnetic field data from the Geomagnetic Observatory of L’Aquila during the period 2008-2009. Magnetic data are investigated by means of conventional techniques of polarization ratio and fractal analysis. In addition, total geomagnetic field data from the INGV Central Italy tectonomagnetic network were also investigated using the simple inter-station differentiation method. Our study does not show any anomalous signal that could be undoubtedly related to the seismic activity.
