A State in India Was Struck by Lightning More Than 36,000 Times in 13 Hours
The intense currents of a lightning discharge create a fleeting but very strong magnetic field. Where the lightning current path passes through rock, soil, or metal these materials can become permanently magnetized. This effect is known as lightning-induced remanent magnetism, or LIRM. These currents follow the least resistive path, often horizontally near the surface   but sometimes vertically, where faults, ore bodies, or ground water offers a less resistive path.
Lightning-induced magnetic anomalies can be mapped in the ground,   and analysis of magnetized materials can confirm lightning was the source of the magnetization  and provide an estimate of the peak current of the lightning discharge. Research at the University of Innsbruck has found that magnetic fields generated by plasma may induce hallucinations in subjects located within meters of a severe lightning storm.
Contrary to the common expression, lightning can and often does strike the same place twice.
Some high energy cosmic rays produced by supernovas as well as solar particles from the solar wind, enter the atmosphere and electrify the air, which may create pathways for lightning bolts. In many cultures, lightning has been viewed as part of a deity or a deity in and of itself.
Verses in the Jewish religion and in Islam also ascribe supernatural importance to lightning. In Christianity , the Second Coming of Jesus is compared to lightning. The expression "Lightning never strikes twice in the same place " is similar to "Opportunity never knocks twice" in the vein of a "once in a lifetime" opportunity, i. Lightning occurs frequently and more so in specific areas.
Since various factors alter the probability of strikes at any given location, repeat lightning strikes have a very low probability but are not impossible. Some political parties use lightning flashes as a symbol of power, such as the People's Action Party in Singapore , the British Union of Fascists during the s, and the National States' Rights Party in the United States during the s.
In French and Italian, the expression for "Love at first sight" is coup de foudre and colpo di fulmine , respectively, which literally translated means "lightning strike". Some European languages have a separate word for lightning which strikes the ground as opposed to lightning in general ; often it is a cognate of the English word "rays".
The name of Australia's most celebrated thoroughbred horse, Phar Lap , derives from the shared Zhuang and Thai word for lightning. The bolt of lightning in heraldry is called a thunderbolt and is shown as a zigzag with non-pointed ends.
This symbol usually represents power and speed. The lightning bolt is used to represent the instantaneous communication capabilities of electrically powered telegraphs and radios. It was a commonly used motif in Art Deco design, especially the zig-zag Art Deco design of the late s. A lightning bolt is also the NATO symbol for a signal asset.

Fourth of July one of most hazardous times for lightning
Warner, M. Ferro, A. Helsdon Jr, and R. The time between the flash of light and thunder will tell you how far you are from where the lightning struck. If you said light travels faster than sound, you're right! The lightning and thunder are happening at the same time, but light reaches you instantly, while sound takes longer.
Do you ever see lightning without hearing thunder? Some call that "heat lightning," but it is really lightning that is over 15 miles away and too far away for you to hear the thunder! Sound travels through air at about to feet per second our default is That is a little more than one mile per five seconds.
This approximation will give you a good idea of how far away the lightning was. Enter the number of seconds from the flash of lightning until you hear the start of the thunder rumble. If you wish, you can adjust the speed of sound to your preferences; however, under most situations, our default should be used. You should not deviate above or below feet per second.
