Experimental results showed that the rock samples with low mechanical resistance, tuff and rhyolite, were destroyed, while the rock sample with high mechanical resistance, i.e., granite, was not broken by lightning strikes. These results indicate that natural lightning causes rocks and bedrock to break.
Scientists have known for decades that lightning can rapidly heat rock to over 2,000 kelvins near the strike point. Organic material on the surface burns off, and part of the rock itself melts almost instantaneously, later cooling to form a glassy surface layer called a fulgurite.
Lightning can create breaks and cracks in brick, concrete, stone, and even cinderblock. Chimneys can take a significant amount of damage, being made from brick and stone.
Although every lightning strike is different, damage to the antenna, electrical system, rear windshield, and tires is common.
Fulgurites are natural tubes or crusts of glass formed by the fusion of silica (quartz) sand or rock from a lightning strike. Their shape mimics the path of the lightning bolt as it disperses into the ground. All lightning strikes that hit the ground are capable of forming fulgurites.
Positive lightning can strike ground up to 10 miles from a storm, even with blue sky overhead. Strikes from “negative lightning” are the more common, typically occurring within 5 miles of a storm. Learn to use thunder as a safety indicator.
“Petrified lightning” is a permanent record of the path of lightning in earth, and is called a fulgurite, after fulgur, the Latin word for lightning. Fulgurites are hollow, glass-lined tubes with sand adhering to the outside.
during a thunderstorm. Refrain from touching concrete surfaces: Lightning can travel through the metal wires or bars in concrete walls and flooring, such as in the basement or garage.
When lightning hits a tree, damage can range along a scale from minimally invasive to explosive. As soon as lightning strikes the tree, water in its cells can start to boil causing steam to form. The expanding steam can explode, cracking bark or even stripping it off the tree.
Lightning usually strikes an aircraft on the front side of the plane's cockpit. The edge of the cockpit window is a typical point of impact. The aluminium fuselage of the aircraft conducts electricity well, and due to that, the lightning discharge does not affect the inside of the aircraft.
Yes, lightning commonly causes structural damage. So-called cold bolts of lightning, following their way to the ground through concrete (which is a better conductor than air) often provide enough force to fragment the concrete.
The heat and electric sparks often result in fire, which can totally destroy a tree. The force of the lightning strike often splits a tree in half or breaks off several boughs.
Lightning storms turn methane into soot (carbon) which as it falls hardens into chunks of graphite and then diamond.
Power surge damage: If lightning chooses electrical wiring as its primary or secondary path, the explosive surge can damage all the appliances it is connected to. Shock wave damage: Lightning produces shock waves that can be destructive. These shock waves can fracture concrete and brick and stone chimneys severely.
Lightning is a major cause of storm related deaths in the U.S. A lightning strike can result in a cardiac arrest (heart stopping) at the time of the injury, although some victims may appear to have a delayed death a few days later if they are resuscitated but have suffered irreversible brain damage.
A downburst can easily overturn a mobile home, tear roofs off houses and topple trees. Severe thunderstorms can produce hail the size of a quarter (1 inch) or larger. Quarter- size hail can cause significant damage to cars, roofs, and can break windows.
You may also feel a physical tingling sensation throughout your body, especially in your extremities. This is often the gut feeling that people get when they "sense" that something is impending. If your hair is standing up, you may have only a few seconds to protect yourself from lightning.
Although the vast majority of lightning strike victims survive, the effects can be serious and long-lasting. Survivors have experienced debilitating injuries, burns and ongoing disability, including symptoms like seizures and memory loss.
Most indoor lightning casualties and some outdoor casualties are due to conduction. Whether inside or outside, anyone in contact with anything connected to metal wires, plumbing, or metal surfaces that extend outside is at risk.
No. Lightning can travel through plumbing. It is best to avoid all water during a thunderstorm.
Copper and its alloys are the most common materials used in lightning protection.
A direct hit from a lightning bolt is so powerful that it can split stone, brick, cinderblock, and concrete with ease.
Perhaps the strangest colors reported are instances of pink or green lightning seen during snowstorms. The phenomenon, known as”thundersnow”, is rare. The unique sky color is caused as snowflakes refract and reflect the white bolt in a unique way.
In the United States, the lifetime odds of being struck by lightning are only 1 in 15,300. In any given year, those odds increase to about 1 in 1.2 million. Interestingly enough, most people survive. If you are struck by lightning the chance of it being fatal is only 1 in 10, a 90% survival rate.
