Popis:	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.
