Forest fires are generally consciously or unconsciously the work of man for various reasons. Fires generated by voltaic arc between power lines and the underlying trees do not occur often. These few cases may be only demonstrated by analyzing around the site where the arc may have been generated. Material such as leaves, bark and soil can be analyzed to find the metallic residues from the fused cables. The electrical cables usually composed of aluminum or copper alloys, when involved in an electric arc may spray fused micro-drops of metals, increasing the natural level of such elements. In two cases, the Al and Cu concentrations were increased by between 2.56 to 13.9 times the background levels. Electron microscopy of leaf surfaces has identified some profound alterations produced by the intense heat of the electrical discharge.
