Summary: | For geodynamically active regions of the Earth, the task of geophysical monitoring is very urgent; geodynamic processes act on geophysical properties and fields. A successful solution to the problem of separating a magnetotelluric field into endogenic and exogenic components allows detection of the moment of fissure initiation, but so far without localization of the active area. For such localization (as a first approximation, direction finding), it is possible to monitor the seismoacoustic field, which is also associated with fissuring. The article describes the development and testing of a three-axis gradient system for recording the seismoacoustic field. Its technical support and requirements are considered in detail. The article presents the results of testing the system at fixed stationary points of the Scientific Station of the Russian Academy of Sciences in Bishkek. Such a gradient system gives grounds to separate sources by the direction to them owing to the presence of a vertical and two transverse components. |
