Theory of the piezomagnetic effect in titanomagnetite-bearing rocks [PDF]
, 1972 The stress sensitivities S x and S R of susceptibility and remanence for titanomagnetite-bearing rocks are calculated in terms of magnetostriction constants λ 100 and λ 111 and anisotropy constants K 1 , K 2 of the magnetic minerals.

Tectonomagnetic experiments and observations in wastern U.S.A.
Journal of geomagnetism and geoelectricity, 1976 Simultaneous measurements of the geomagnetic field with differential proton magnetometers (0.25 gamma sensitivity) have been recorded periodically since 1973 at more than 100 pairs of sites, 8 to 12km apart, along active faults in western U. S. A.

The INGV tectonomagnetic network: 2004–2005 preliminary dataset analysis [PDF]
Natural Hazards and Earth System Sciences, 2006 Abstract. It is well established that earthquakes and volcanic eruption can produce small variations in the local geomagnetic field. The Italian Istituto Nazionale di Geofisica e Vulcanologia (INGV) tectonomagnetic network was installed in Central Italy since 1989 to investigate possible effects on the local geomagnetic field related to earthquakes ...

Effect of hydrostatic pressure on viscous remanent magnetization in magnetite-bearing specimens [PDF]
, 1995 Rocks at depth in the crust acquire a viscous (i.e., time-dependent) magnetization under the pressure-temperature conditions at which they reside. There have been numerous studies on the effect of temperature on viscous magnetization but little work has ...

Anomalous Geomagnetic Variations Possibly Linked with the Taiwan Earthquake (
, 2011 On 19 December 2009, the eastern part of Taiwan at approximate depth of 45 km was struck by a strong earthquake (Mw=6.4). The epicenter was located about 20 km away from the Hualien (HLN) station in Taiwan.

The development of the INGV tectonomagnetic network in the frame of the MEM Project [PDF]
Natural Hazards and Earth System Sciences, 2007 Abstract. In the middle of 1989, the INGV (Italian Istituto Nazionale di Geofisica e Vulcanologia) installed in Central Italy a network of magnetic stations in order to investigate possible relationship of the local magnetic field with earthquakes occurrences. Actually the network consists of four stations, where the total magnetic field intensity data

Results and perspectives of tectonomagnetic investigations in the Western Antarctic
Annals of Geophysics, 2009 The results of long-term (1998-2005 yrs.) tectonomagnetic investigations in the Western Antarctic near the location of Ukrainian Antarctic Station «Academic Vernadsky» are reviewed. The peculiarities of the Earth’s anomalous magnetic field and its dynamic temporal variations (tectonomagnetic anomalies) were studied using the newly founded ...

Diurnal changes of earthquake activity and geomagnetic Sq-variations [PDF]
, 2003 Statistic analyses demonstrate that the probability of earthquake occurrence in many earthquake regions strongly depends on the time of day, that is on Local Time (e.g. Conrad, 1909, 1932; Shimshoni, 1971; Duma, 1997; Duma and Vilardo, 1998).

The Hawaiian-Emperor Chain [PDF]
, 1989 Intraplate volcanism within the Pacific Plate not generated at spreading plate margins is most obvious in Hawaii and the Hawaiian-Emperor volcanic chain. This chain forms a global relief feature of the first order.

Contamination due to the tidal movement of sea-water in tectonomagnetic data.
Journal of geomagnetism and geoelectricity, 1985 Geomagnetic observations have intensively been carried out since 1976 in the Izu Peninsula, Japan, in an attempt to search for precursory and coseismic changes in the geomagnetic field. In order to enhance the significance of such changes, it is indispensable to clarify noises in the observed geomagnetic field.
