The mysterious "Relámpago del Catatumbo" (Catatumbo lightning) is a natural phenomenon located at the mouth of the Catatumbo river in Venezuela.
Cloud to cloud lighting forms above the area 140-160 nights a year, for up to ten hours a night. Lightning may travel from one cloud to another up to 280 times an HOUR.
Several different explanations have been proposed for the near constantly lightning storm, including methane produced from local swamps, oil deposits, uranium in the bedrock and local air currents. No one explanation has so far been universally accepted and the cause is still debated today.
