precursor

In the article presented methods of the directed monitoring of acoustic background in an infrasound range by means of the area system of grouping of microbarographs, and also methods of the directed monitoring by the radiotechnical complex of radioroutes of VLF signals. The first results over of remote supervisions of seismoactivity Vranchea region are brought with the use of the considered methods, anomalous effects are distinguished in the looked after fields before earthquakes.

Purpose. In world practice there are observations of variations of induction vectors related to geodynamic processes. The purpose of this work is to compare time series of induction vector components at two Japanese stations Esashi (ESA) and Mizusawa (MIZ), located on the east coast of Honshu island at a distance of 19 km from each other, with a seismic activity in the region. Methodology.
