摘要: Tectonomagnetic field observations from absolute magnetic level measurements were undertaken in Central Italy an area extending between latitude 41°N and 43°N longitude 13°E 15°E. Moreover,natural electromagnetic signals a system of two VLF search coil wide-band antennas collected at the geomagnetic observatory L Aquila (42o23'N, 13o19'E). The analysis these data allowed investigation of properties study at different time spatial lengthscales. Tectonomagnetic field obtained comparing simultaneously recorded three magnetometer stations using L'Aquila Observatory as reference for differentiation. We report on evolution indicators related to local regional seismic activity.
