| Abstract: | The features of the use of a combined receiver that is able to record acoustic pressure and three mutually orthogonal components
of its gradient simultaneously in a region of small wave sizes are discussed. This method can be used to record geoacoustic
emission signal anomalies, which could be treated as useful earthquake precursors. Possible methods of solving this problem
are considered using an example of the analysis of such anomalies that occurred during strong seismic events in Kamchatka. |
