摘要
The ionospheric response to the transit of acoustic waves from a number of the strongest submarine earthquakes with magnitudes M (w) a parts per thousand yen 7.7, which occurred during the past few years, is analyzed. The amplitude of the response in the detrended TEC is studied as a function of the magnitude and vertical component of the surface deformation. It is shown that the geomagnetic field can significantly modulate the shape of the ionospheric response, depending on whether the perturbation propagates equatorward or polarward.
