Self initiated arc, I don't believe they happen often:
More than 20 years ago the power company I worked for, settled a large sum with DNR for allegedly igniting a forest fire. An energized 115kv line went over the hill on which a forest burned, and indeed remained energized until later into the fire fighting efforts when the power company thought it would be wise to shut it down. Many months after the fire, the DNR claimed that a "spark jumped from the line" despite lack of protective device operation on that line, and despite two eyewitnesses of smoke originating from a location several hundred feet away from the power line. In federal court it became apparent the DNR had a compelling case and the power company settled quickly.
Well the PoCo should de-energize all lines crossing any DNR property to be sure this never happens again
