摘要:	摘要： •The seismo-ionospheric electrostatic coupling is theoretically examined.•Penetration of the seismogenic electric fields into the ionosphere is inefficient.•We predict a seismomagnetic effect in the topside ionosphere. In this paper we present the results of the computation of the electric and magnetic fields produced in the ionosphere by the near-earth seismogenic disturbance in the vertical atmospheric electrostatic field under different ionospheric conditions. It is shown that in the nighttime ionosphere during solar minimum and inside large-scale plasma bubbles, the magnitude of the transverse electric field can attain ∼0.2 and 1.0mV/m, respectively. The seismomagnetic effect with the magnitude of ∼13pT is predicted in the topside daytime and nighttime ionosphere at any solar activity. 出版者： Elsevier Ltd 出版日期： 2015-10-15 出處： Advances in space research, 2015-10, Vol.56 (8), p.1707-1713 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2015 COSPAR 識別號： ISSN: 0273-1177 識別號： EISSN: 1879-1948 識別號： DOI: 10.1016/j.asr.2015.07.034
