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).
Sa punto ay maaaring Lumitaw "at natural kidlat baras" (sa underground), Iyon diverts ang naglalabas kasalukuyang Mabilis na medyo hindi bababa sa ang ilang mga metro underground, kasama ang pangalawang o parallel effect (koryente, induction) sa labas ng ang abot at medyo Tumpak na bilog din at lamang ng minimal na epekto sa itaas lupa. Genus ay maaaring ng geological pinagmulan (springs, mga faults), arkeolohiko (bakal, tanso edad), kahit modernong (digmaan eroplano gumuho, mga utility engineering).
