Tiny lightning bolt explosions can vaporise the moon’s thin soil
Mini-lightning may flash in the coldest craters on the moon, melting and vapourising soil. All that sparking could have altered the surface as much as impacts from incoming rocks and dust.
The outer layer of the moon is a sort of history book recording the interactions between the moon and the rest of the solar system. To correctly interpret that history, we need to understand the mechanisms that shape it.

Volcano eruptions can produce lightning!
Mount Etna spectacularly exploded on the 3rd of December 2015 for the first time in two years, sending a plume of volcanic ash scorching through the sky. The cloud was lit up with the astonishing sight of a "dirty thunderstorm", which causes lightning to streak through a cloud of ash. This natural wonder occurs when tiny fragments of rock, ash and ice rub together to produce static electricity.

An incredible 45 day storm turned California into a 300-mile-long sea — and it could happen again.
A massive 19th century storm in the pacific United States opened up a 300-mile-long sea that stretched through much of the central part of California. For 43 days, from late 1861 to early 1862, it rained almost nonstop in central California. Rivers running down the Sierra Nevada mountains turned into torrents that swept entire towns away.

Storm sank 4 ships on Lake Erie in 1916
Some call it Lake Erie’s “perfect storm,” one so powerful 100 years ago that it caused four ships to sink within 18 hours.
In all, 49 lives were lost in the lake’s Canadian waters, but those crew members are being remembered right here in Toledo.
“This massive [storm] affected communities across the lake,” said Carrie Snowden, archaeological director for the Toledo-based National Museum of the Great Lakes, and who is giving a presentation about the storm during a lecture series today. “This storm is Lake Erie’s own perfect storm; this coming together of different weather fronts to create something horrific on top of Lake Erie. The human loss is of greater significance.”

Why is lightning white?
Static charges form in a storm composed of ice crystals and liquid water drops. Turbulent winds inside the storm cause particles to rub against one another, causing electrons to be stripped off, making the particles either negatively or positively charged.
The charges get grouped in the cloud, often negatively charged near the bottom of the cloud and positively charged up high. This is an electric field and because air is a good insulator, the electric field becomes incredibly strong. Eventually a lightning bolt happens and the flow of electrons neutralizes the electric field.
This flow of electrons through the lightning bolt creates a very hot plasma, as hot as 50,000 degrees, that emits a spectrum of electromagnetic energy. Some of this radiation is in the form of radio waves and gamma rays.
Instruments that measure these electromagnetic waves allow us to detect lightning bolts that are very far away. Visible light is also part of the spectrum of energy.
At these temperatures, laws of physics state that most of the visible light will be at a wavelength perceived as the color blue, although all wavelengths will be emitted.
The notion of color applies to our perception of what we see, not to the light itself. When we talk about the color of light, we really mean the color we sense with our eyes and then interpret with our mind.
Thus, while the peak energy is at blue wavelengths, the intensity of all the colors tends to saturate our eyes, leading us to perceive the color white – which includes all wavelengths in the visible spectrum.
Over the last 20 years scientists have discovered that lightning also shoots upward out of the top of thunderstorms into the upper atmosphere. These lightning types have distinctive colors, including red sprites and blue jets.

Earthquake lightning?
What was that strange light in the sky?
Many people overnight reported seeing strange lights in the sky, a phenomenon that has been reported for centuries before, during, and after earthquakes.
Seismologists aren't in agreement about the causes of the hotly-debated phenomenon - called earthquake lights or, sometimes, earthquake lightning.
And, of course, it's not clear whether the lights overnight in New Zealand were the phenomenon, or something else.
One theory suggests dormant electrical charges in rocks are triggered by the stress of the Earth's crust and plate tectonics, transferring the charge to the surface where it appears as light.
Historical reports include globes, or orbs, of glowing light, floating just above the ground or in the sky.
Much like tidal research, it is an area that is notoriously difficult to investigate. Tidal stresses and their effects on the Earth are minute, but measurable, although many seismologists remain unconvinced by theories of "tidally triggered" earthquakes.
With "earthquake light", the phenomenon is also notoriously difficult to observe, study, and measure.
GNS seismologist Caroline Holden said there were anecdotal reports of lights in the sky.
"Unfortunately, we cannot measure this phenomena or its extent with our instruments to provide a clear explanation," she said.
The phenomenon has been documented for centuries.
Hypotheses have suggested the movement of rocks could generate an electric field, others suggest quakes can lead to rocks conducting electromagnetic energy and a subsequent build up of electric charges in the upper atmosphere.
Yet another theory suggests a link between the electric charge, or current, released by the earth ripping and buckling below the surface, and the magnetic properties of rock.
The charge appears as light, so the theory goes.
People reported similar strange lights in the sky during the 2011 Christchurch earthquake.
In 1888, before a large quake around the Hanmer region, a strange glow in the sky was reported by observers.
One recent study documented hundreds of sightings of strange light, glowing, and aurora-like reports, from 1600 to the 19th century.
The study in the Seismological Research Letters suggested a charge builds up in rock inside the Earth's crust and, as it becomes rapidly unstable in a quake, expands outward.
In an earthquake, the electrical charge transfers from below the surface to the surface, or above, depending on the conductivity of the rock - appearing as light.
"When such an intense charge state reaches the Earth's surface and crosses the ground–air interface, it is expected to cause [an electric transmission and breakdown] of the air and, hence, an outburst of light.
"This process is suspected to be responsible for flashes of light coming out of the ground and expanding to considerable heights at the time when seismic waves from a large earthquake pass by."
The study said some seismologists also think the theory could account for other phenomena, such as changes to electrical fields, strange fog, haze, clouds, and low-frequency humming or radio frequency emission.
In the study, the researchers found the light was more often associated with a type of quake in which tectonic plates are wrenched apart, known as a "rift" earthquake

...what a moonbow is?
Moonbows, also known as lunar rainbows, are the dimmer cousin of more common daylight rainbows, made possible from the refraction of raindrops by moonlight, rather than sunlight.
Moonbows are so rare because moonlight is not usually bright, and the alignment of conditions needed for them don't happen often.
According to Atmospheric Optics, a bright near-full moon must be less than 42 degrees above the horizon, illuminating rain on the opposite side of a dark sky.

Lightning protection tents exist!
The probability of getting struck by lightning is statistically very rare, but alas, storm-attributed deaths and injuries stretch into the low thousands on an annual basis. About 96% of those struck were in open environments when hit. A majority — as you may expect — come from frequent participators in outdoor activities such as hiking, camping, and climbing. Industrial designer kama jania’s ‘bolt’ line of tents was created to increase the safety of those unfortunate to be in the wrong place when the weather turns.

On July 13, 1977, New York City endured a 25-hour blackout after lightning strikes power lines, prompting widespread arson, looting, and riots. The blackout was to many a metaphor for the gloom that had already settled on the city. An economic decline, coupled with rising crime rates and the panic-provoking (and paranoia-inducing) Son of Sam murders, had combined to make the late 1970s New York’s Dark Ages.

Roy Cleveland Sullivan was a United States park ranger in Shenandoah National Park in Virginia. Between 1942 and 1977, Sullivan was hit by lightning on seven different occasions and survived all of them. For this reason, he gained a nickname "Human Lightning Conductor" or "Human Lightning Rod". Sullivan is recognized by Guinness World Records as the person struck by lightning more recorded times than any other human being. He died from a self-inflicted gunshot wound at the age of 71 over an unrequited love.

...Lightning strikes Catatumbo River in northern Venezuela 280 times per hour, 260 nights per year!
A lightning storm rages almost constantly at the mouth of the Catatumbo River in northern Venezuela, with bolts striking up to 280 times per hour for 10 hours a day, on 260 nights every year. That's 28 lightning strikes per minute for those nights - and about 1.2 million lightning strikes each year.
Venezuela, home of the delicious pabellón criollo, has been experiencing the Catatumbo lightning for hundreds of years now. It comes from storm clouds that amass more than 3,200 feet above the spot where the Catatumbo River flows into Lake Maracaibo. According to meteorologists, winds going across the lake and its surrounding swamps are likely responsible for the storms. The swamps are plains surrounded by mountains - the Andes (home of the first cultivation of quinoa), the Perijá Mountains, and the Cordillera de Mérida - and the combination of heat and moisture in the area creates electrical charges that - when met with wind destabilized by the mountain ridges - turns into lightning and thunderstorms.
Light flashes from the storm can be seen up to 25 miles away, earning the phenomenon the nickname "The Maracaibo Beacon," and it's been used by ships for navigation as a result.
The frequency of the lightning strikes changes both within the year and from one year to the next. October's wet season is peak time for the storms, while they generally calm down in January and February. In fact, there was a break in the storm due to a drought between January and March of 2010, and locals feared that the phenomenon was over for good.
The Catatumbo lightning holds a special place in the heart of Venezuelans, because it may have been partially responsible for the nation's independence. An attempted surprise attack led by British navigator Sir Francis Drake on the Spanish army was spoiled by the bright lightning one night in 1595, a story that was later recounted in Lope de Vega's epic La Dragontea a few years later. Years later, in the early nineteenth century, the Spanish army itself attempted a sneak attack on Maracaibo in order to take back the country towards the end of the Venezuelan War of Independence. Again, the Catatumbo lightning lit up the landscape, thwarting the invasion and allowing Venezuela's beloved revolutionary hero, Simón Bolívar, and his fleet to win one of the last and most important battles in the wars against the Spanish for independence.
The Catatumbo lightning has also been responsible for producing more ozone at the mouth of the Catatumbo than any other place in the world. Scientists have expressed doubt, however, that this will have any effect on the world's ozone layer, due to the lightning's instability. Its effect on tourism, however, is not in doubt, as sightseers have flocked to the region to join nighttime tours to see the lightning. It's a great addition to any South American itinerary.
