| Abstract: | The design of a 2D small aperture seismic array (SASA) installed in the central part of the East European Platform (in the area of the village of Mikhnevo, Moscow Oblast’) is discussed. Brief information is provided on the geologic structure of the upper section. The SASA configuration is described along with parameters of the seismological instrumentation used, and the digital seismic data acquisition system. Results are described from a study of the spectral content and the spatial correlation properties of short period microseismic noise and seismic signal coherence. Examples are provided of records of natural and manmade seismic events occurring at different epicentral distances. Experimental data are analyzed to show that this small aperture seismic array can be an effective tool to study low magnitude seismicity in the East European Platform and for solving several other problems arising in contemporary experimental seismology. |
