An analytical expression for early electromagnetic signals generated by impulsive line-currents in conductive Earth crust, with numerical examples

[摘要] Changes in the electromagnetic (EM) field after an earthquake rupture but before the arrival of seismic waves (“early EM signals”) have sometimes been reported. Quantitative evaluations are necessary to clarify whether the observed phenomena are accounted
