摘要：
The GPS-signals recorded as the ionospheric response to the transition of the acoustic waves after a series of the strongest (with magnitude M (w) a parts per thousand yen 8.2) seaquakes are analyzed. It is shown that the signals may contain information about the energy characteristics of these seismic events. The seismic energy estimates for such events based on the shape of the characteristic perturbation in the ionospheric total electron content (the duration of the compression phase of the shock wave) agree with the estimates inferred from the seismic data and can be obtained within 15 min after the event.
