Magnetic Field Observations Close to the Epicenter of the 2009 L´Aquila Earthquake.

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

A new station for monitoring electromagnetic fields in Duronia (Italy): experimental setup and first results

<p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 9.0px Times;">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</p> <p style="margin: 0.0px 0.0px 0.0px 0.0px; font: 9.0px Times;">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 Alfvén 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.</p> <br /> <br /&gt

Geomagnetic Observation Result, 2013-2014

This report describes the activities performed from November 2, 2013 to December 3, 2013. For the present work H, D and Z INTERMAGNET formatted data from the fluxgate magnetometer EDA have been used. The proton precession magnetometers used to record F total values were Overhauser type; for a description of instruments we refer to geomagnetism text books, for example Parkinson (1983) and Wienert (1970). Since the total intensity F time variations, at polar latitudes, where values of inclination is almost 90, are very close to the vertical component Z time variations, the plots of total intensity time variations are not shown. They can however be obtained from the well known equation:ingvPublished1A. Geomagnetismo e Paleomagnetismo5IT. Osservator
