Catatumbo Lightning

Catatumbo Lightning


The Catatumbo Lightning is an atmospheric phenomenon in Venezuela. It occurs only over the mouth of the Catatumbo River where it empties into Lake Maracaibo. The frequent, powerful flashes of lightning over this relatively small area are considered to be the world's largest single generator of tropospheric ozone, that is, ozone that does not replenish the stratospheric ozone layer.

It originates from a mass of storm clouds at a height of more than 5 km during 140 to 160 nights a year, 10 hours per day and up to 280 times per hour. After appearing continually for centuries, the lightning ceased from January to April 2010, apparently due to drought. This raised fears that it might have been extinguished permanently. The phenomenon reappeared after several months
