The INGV tectonomagnetic network [PDF]
Advances in Geosciences, 2008 Abstract. The Italian Istituto Nazionale di Geofisica e Vulcanologia (INGV) tectonomagnetic network was installed in Central Italy since the middle of 1989 to investigate possible magnetic anomalies related to earthquakes. The network is part of the INGV L'Aquila Geomagnetic Observatory and is located in an area extending approximately in latitude ...

The time-dependence of electromagnetic response functions [PDF]
, 1982 Dynamic processes within the Earth are capable of modifying many of its physical properties. This review considers the modification of electrical resistivity mainly by time-changes in the stress field experienced by crustal materials.

Tectonomagnetic studies in Tajikistan.
Journal of geomagnetism and geoelectricity, 1978 High-precision simultaneous observations of the geomagnetic field have been made over areas with fault displacements and junctions of mountain structures in Tajikistan using proton magnetometers MPP-1 with 0.1 γ sensitivity. The optimal duration and frequency of resurveying as well as the detection level of possible tectonomagnetic variations (0.6 γ ...
