“…Seismic activity in arctic latitudes under an ice layer is accompanied by acoustic deformation of ice cover [1]. Acoustic elastic waves occur in an ice layer in the rage from units to tens of kHz [2,3,4,5]. In order to record earthquake sources deep under the water and far away from an ice edge, we need to develop mathematical models for the processes of elastic acoustic wave propagation at the boundary of water and ice.…”

Developed experimental facility allows one to generate acoustic pressure within the intervals from 105 to 106 Pa with an affective system of matching layers of bottom, water and ice. Theoretical and experimental investigations showed the possibility of information transfer in a shallow sea under an ice layer. Experimental acoustic system allows one to make measurements in a wide frequency range from 40 to 1100 Hz. The conducted investigation can be used to develop effective remote communication and to model earthquake acoustic precursor measurements.

“…Among the preseismic anomalies of the near-surface fields, increase of high-frequency geoacoustic emission in kilohertz frequency range [5][6][7][8][9] and bay-like decrease of atmospheric electric field with sign change during calm weather conditions [10][11][12][13][14][15] are observed. Anomalies of these fields, essentially different, occur in solid and air mediums and have different polarity that indicates various mechanisms of formation.…”

The authors generalize and analyze the investigation results of joint anomalies of high-frequency geoacoustic emission and atmospheric electric field by the ground–atmosphere boundary which were detected by them in Kamchatka. These anomalies are observed as geoacoustic emission increases in kilohertz frequency range and bay-like decreases of atmospheric electric field with the sign change which occur close in time during calm weather conditions. It is the authors’ opinion that the common nature of these anomalies is short-time stretching of the near-surface sedimentary rocks at an observation site during unstable tectono-seismic process. A scheme of the detected anomalies formation has been suggested.

“…The paper [1] experimentally proves that deformation-acoustic activity which appears before earthquakes may be considered as a complex precursor of a seismic event. One of the methods to record earthquake precursors is the method of acoustic elastic wave recording in the range from 0 to 10 kHz in small water pools [2][3][4][5].…”

An adjustable pneumatic generator of acoustic signals with shock excitation was developed. Measuring and computing complex was also created to investigate elastic acoustic wave propagation along ice surface. Experiments on low-frequency acoustic signal propagation from the pneumatic generator were carried out in «water-ice-air» system. The possibility to apply the developed measuring and computing complex for physical modeling of acoustic wave propagation from earthquake sources along ice cover was confirmed.
