- Abstract
Numerous are the testimonies of electromagnetic signals precursors of seismic events detected with the most different modalities, starting from the radio signals received from radio amateurs to arrive at themonitoring of particular frequencies of the electromagnetic spectrum not only by institutional bodies but also by amateurs. This article concerns anomalous electromagnetic signals detected in the ELF band from a dedicated monitoring station, located in Trasaghis in the province ofUdine, correlated to a series of seismic events (max 3.9 Richter) occurring in the Tolmezzo - Verzegnis - Venzone area province of Udine (Italy) between June, 16 and July, 07, 2019. The station detected the first anomalous signals eighteen days and then again three days before themain event. The signals then continued even further, probably indicating the continuing state of tension, as evidenced by the subsequent seismic events. The detected signals are located in the band between 1 and 10 Hz, and were detected by a very high inductance antenna connected to a standard seismic station. The similarity with other signals detected by the twin station of Pasian di Prato (UD) during the events of 2016-2017 in central Italy is significant. It is therefore suggested to use a mobile station in order to detect the state of seismic stress in an area already affected by an important seismic event for prevention and civil protection purposes.
