13°19E) monitors possible seismo- or tectonomagnetic effects in Central Italy, using LAquila Observatory as a
reference for differentiation. A system of two VLF search coil wide-band antennas, working in two different frequency
bands, at the LAquila Observatory, monitors possible electromagnetic effects related to seismic events
occurring in Central Italy. Absolute magnetic field observations and VLF signals have been collected for several
years. In particular the tectono-magnetic network started its operations in 1989. In this paper we report on the
time variation of above mentioned data for the most recent years 2002 and 2003, also in connection with older
measurements time series; we also report on seismic activity recorded in this area by the national seismic network.
In the above mentioned time interval, no strong earthquake activity was recorded, and at the same time no
clear evidence for magnetic or electromagnetic signals related to seismic events was found.
