ResumenOn average, about 100 lightning discharges occur every second on the Earth. When lightning strikes soil, sand or rock, the high temperatures reached (about 30.000 ºK) promote the formation of melted glass tubular structures known as fulgurites. In the case referred here, lightning stroked a soil (granitic sand plus angular stones of thick-grained two-mica granite) and allochthonous materials supporting the platform of an electric tower. The intense melting produced a cylindrical rod, from which, as if they were roots of a tree, several bifurcating horizontal and subhorizontal branches of decreasing thickness were attached (see figure below).
