Abstract

The GPS-signals recorded as the ionospheric response to the transition of the acoustic waves after a series of the strongest (with magnitude M ≥ 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.

Abstract

The article reports on the findings of a study published in the August 6, 2015 issue of "Science," by Jean-Philippe Avouac and colleagues regarding the seismic characteristics of the April 25, 2015 Nepal earthquake. Topics addressed include comments on how the quake could have been worse if its wave structure were different, how the quake was caused by low-frequency vibrations, and discussion of how to identify buildings which are particularly vulnerable to this kind of vibration.
