On the point may appear "a natural lightning rod" (in the underground), that diverts the discharge current quite quickly at least several meters underground, so its secondary or parallel effects (electricity, induction) outside of the reach a fairly accurate circle take only a minimal effects above ground. The rod may be of geological origin (springs, faults), archeological (iron, bronze age), even modern (collapsed war aeroplane, engineering utilities).
Juu ya hatua inaweza kuonekana "na asili umeme fimbo" (chini ya ardhi katika), Hiyo unatoa usaha sasa Haraka kabisa angalau kadhaa mita chini ya ardhi, pamoja na madhara yake ya sekondari au sambamba (umeme, introduktionsutbildning) nje ya kufikia na uungwana sahihi mduara pia na athari ndogo tu juu ya ardhi. jenasi inaweza kuwa asili ya kijiolojia (chemchem, makosa), archeological (chuma, shaba umri), hata kisasa (vita ndege kuanguka, yanayotoa uhandisi).
