Abstract
Since the end of 2007 a new electromagnetic field monitoring station has been in operation in Central Italy in the area of a village called Duronia. The station was created in the framework of the MEM (Magnetic and Electric fields Monitoring) Project composed of a team headed by the Abruzzo region. The main target of the MEM Project is to create in the Adriatic Area a network of observatories to monitor the environmental electromagnetic signals in the frequency band from 0.001Hz to 100kHz (ULF-ELF-VLF). The peculiarity of the Duronia installation is the low electromagnetic background noise of the site and the low noise of the instrumentation. Here we show the experimental setup, with a brief discussion on the installed instrumentation and on the preliminaresults obtained in the first months of operation. The research activity is mainly focused on the analysis of the spectral structure of the Schumann Resonance in the range of frequencies [5.0-35.0]Hz, and the Ionospheric Alfven Resonator in the range of frequencies [0.1-7.0]Hz and their evolution in time. Another target concerns the long-term monitoring of local magnetic field anomalies possiblelated to the local geodynamical processes.
Highlights
The evolution of the measurement techniques and the ongoing research activity have a considerable importance for a better understanding of the environmental electromagnetic fields (Bianchi and Meloni, 2008)
The main objectives of these studies are both to enhance the knowledge on the natural electromagnetic fields, and study the electromagnetic anomalies associated to anthropogenic sources, the well
We have briefly described the experimental setup showing the characteristics of the installed instrumentation
Summary
The evolution of the measurement techniques and the ongoing research activity have a considerable importance for a better understanding of the environmental electromagnetic fields (Bianchi and Meloni, 2008). Concerning the long term monitoring of the electromagnetic field generated in the Earth’s crust, in the coming years through the analysis of the Inter Station Magnetic Transfer Functions we will be able to study the possible correlation between the geodynamical processes and the local magnetic field anomalies (Palangio et al, 2007; 2008b). For this purpose the Duronia station will be added to the INGV tectonomagnetic network already existing in Central Italy (Meloni et al, 1998; Masci et al, 2006; 2007)
