Lightning Safety Awareness Week is an annual campaign dedicated to educating the public about the significant dangers of lightning and promoting vital safety measures. This initiative began in 2001, spearheaded by NOAA lightning specialist John Jensenius and the National Lightning Safety Council. Its creation was driven by a crucial need to address lightning as an “underrated killer,” aiming to reduce the alarmingly high number of fatalities and injuries it caused each year. Since its inception, the week-long observance is credited with a substantial reduction in U.S. lightning fatalities, dropping from around 55 per year to less than 30 today. Lightning Safety Awareness Week is now recognized nationwide, with organizations like the National Weather Service and various emergency management agencies disseminating educational materials, hosting outreach events, and emphasizing key safety slogans like “When thunder roars, go indoors!”
Electrifying Oddities: Weird Lightning Facts
Beyond the familiar bolts that strike the ground, lightning exhibits some truly bizarre and awe-inspiring phenomena. Perhaps the most mysterious is ball lightning, described as a luminous, often spherical object that can float, move erratically, or even pass through solid objects before vanishing, sometimes with a pop or bang. While sightings have been reported for centuries and it has even been recreated in labs, its true nature remains largely unexplained by science.
Then there are the “Transient Luminous Events” (TLEs), which are not your typical lightning but rather fleeting flashes occurring high above thunderstorms in the upper atmosphere. These include sprites—reddish, jellyfish-shaped bursts of electricity that dance above thunderclouds—and blue jets, cone-shaped beams of blue light that shoot upwards from cloud tops. Even more elusive are elves, rapidly expanding ring-shaped glows that can stretch for hundreds of miles, lasting less than a thousandth of a second. While these atmospheric light shows are fascinating, they remind us that the sky above a thunderstorm is a dynamic and dangerous place. The best view of these phenomena is always from a safe, indoor location!
The immense power of lightning can also leave behind fascinating physical evidence. When lightning strikes sand or soil, the intense heat—up to 30,000°C, five times hotter than the surface of the Sun—can instantly fuse the particles into glass-like tubes called fulgurites. These unique, often branching formations are sometimes referred to as “fossilized lightning” and offer a tangible record of a lightning strike’s path underground.
Beyond these geological oddities, lightning can also trigger “dark lightning,” which generates very little visible light but produces high-energy electrons that collide with air molecules, creating powerful gamma rays. These terrestrial gamma-ray flashes (TGFs) are so intense they can even create antimatter—a truly mind-bending consequence of Earth’s most electrifying natural phenomenon.
The sheer, unimaginable power behind these occurrences is why personal safety should always be your top priority. If you can hear thunder, you are close enough to be struck by lightning, no matter how distant the storm appears.

The Bottom Line
Lightning is one of nature’s most unpredictable and powerful forces. Understanding both its fascinating science and the myths surrounding it can help keep you safe. Remember: when you hear thunder, you’re within striking distance. The only truly safe place during a thunderstorm is inside a substantial building or hard-topped vehicle. Don’t let curiosity or misconceptions put you at risk—when it comes to lightning safety, it’s always better to err on the side of caution.
