Update on monitoring of magnetic and electromagnetic tectonic signals in Central Italy [PDF]
Annals of Geophysics, 2007 A network of three absolute magnetometer stations and the geomagnetic observatory of LAquila (42°23N, 13°19E) monitors possible seismo- or tectonomagnetic effects in Central Italy, using LAquila Observatory as a reference for differentiation.

A tectonomagnetic effect detected in Central Italy
Annals of Geophysics, 1994 Significant variations in the absolute value of the geomagnetic field intensity related to tectonic events, as earthquakes and volcanic eruptions, have been observed in several cases. To detect such a tectonomagnetic effect related to seismic activity, a

Tectonomagnetic and VLF electromagnetic signals in Central Italy
Annals of Geophysics, 2004 Tectonomagnetic field observations from absolute magnetic field level measurements were undertaken in Central Italy in an area extending between latitude 41°N and 43°N and between longitude 13°E and 15°E.

Reviews of Geophysics, 1983 The magnetization of crustal rock is influenced by stress by virtue of piezomagnetic effects in crystals of magnetic minerals. Crustal stress changes in tectonic zones are therefore expected to generate changes in the crustal component of the geomagnetic field and so provide a mechanism for monitoring stress.

Loop Antenna Characterization for ELF and SLF Measurements [PDF]
Revista Elektrón, 2018 Electromagnetic Fields are present in the Earth, due both to natural and artificial emissions. The Electric and Magnetic fields generated by natural events like volcanic eruptions and earthquakes, are aspects of tectonomagnetism, volcanomagnetism and ...

Tectonomagnetism and tectonoelectricity
Reviews of Geophysics, 1987 The last four years has seen a considerable waning of efforts in the U.S. to use the inherent stress sensitivity of the magnetization of rocks in tectonically active regions as a tool for understanding and, perhaps predicting, earthquake activity and volcanic eruptions.

Magnetic Susceptibility of Magnetite under Hydrostatic Pressure, and Implications for Tectonomagnetism [PDF]
Journal of geomagnetism and geoelectricity, 1979 The effects of hydrostatic pressure up to 2.7 kb on the susceptibility of magnetite single crystals, rocks and ore, and synthetic samples were studied. Susceptibility was measured using both static and alternating-frequency methods, with cyclic change of hydrostatic pressure and with time-dependent experiments.

Tectonomagnetic study in the eastern part of Hokkaido, NE Japan: Discrepancy between observed and calculated results [PDF]
Earth, Planets and Space, 2004 ¶Continuous and repeated geomagnetic observations have been performed at 8 stations in the eastern part of Hokkaido, NE Japan, to confirm a detailed picture of geomagnetic secular changes. The observation delineated anomalously large secular changes of about 1 nT/year that have lasted at least for about 3 to 30 years (depending on the period of ...

Piezomagnetic response with depth, related to tectonomagnetism as an earthquake precursor.
Journal of geomagnetism and geoelectricity, 1978 Piezomagnetic field variations can result from tectonic stress changes in the focal zone of an impending earthquake. Interpretation of such observed tectonomagnetic effects requires modeling of the stress response of magnetic properties of the lithosphere.
