There is a place on Earth where an "everlasting storm" appears almost every night, averaging 28 lightning strikes per minute for up to 10 hours at a time. Known as Relámpago del Catatumbo — the Catatumbo Lightning — it can spark as many as 3,600 bolts in an hour. That's one per second.
This storm lives above a swampy patch of northwestern Venezuela, where the Catatumbo River meets Lake Maracaibo, and has provided near-nightly light shows for thousands of years. Its original name was rib a-ba, or "river of fire," given by indigenous people in the region. Thanks to the frequency and brightness of its lightning, visible from up to 250 miles away, the storm was later used by Caribbean sailors in colonial times, earning nicknames like "Lighthouse of Catatumbo" and "Maracaibo Beacon."
The lightning has also played an even larger role in South American history, helping thwart at least two nocturnal invasions of Venezuela. The first was in 1595, when it illuminated ships led by Sir Francis Drake of England, revealing his surprise attack to Spanish soldiers in the city of Maracaibo. The other was during the Venezuelan War of Independence on July 24, 1823, when the lightning betrayed a Spanish fleet trying to sneak ashore, helping Adm. José Prudencio Padilla fend off the invaders.
So what causes such a powerful storm to develop in the same spot, up to 300 nights a year, for thousands of years? Why is its lightning so colorful? Why does it not seem to produce thunder? And why does it sometimes vanish, like its mysterious six-week disappearance in 2010?
