Apparatus for the Measurement of Electromagnetic Activity of Landslides

Abstract

The article presents a new research apparatus for measuring the electromagnetic activity of landslides. The basic element of the apparatus is a highly sensitive underground receiver of the magnetic component of the EM field. Such a receiver inserted to the full depth of a landslide well records the levels of magnetic field amplitude at a given depth. Anomalous levels of the magnetic component indicate the existence of landslide slip planes. Combining several receivers into a measurement system will enable continuous monitoring of landslide activity. The article presents examples of studies using the discussed apparatus, which were carried out on real landslides.
