Is thunder dangerous?

Does thunder mean there is lightning?

Thunder indicates the presense of danger. When lightening moves from a cloud to a cloud or from a cloud to the ground, it leaves a small open path in the air, called a channel. After the lightning is gone, air rushes back into that space and the sound wave the air makes crashing back together is what we hear as thunder. We see the lightning before we hear the thunder because sound does not travel as fast as light does.

Lightning is a current of electricity traveling from one place to another. It is so powerful that if a person were to get between it and the cloud, it can burn or kill that person. To stay safe, it is always a good idea to go indoors whenever you hear thunder, because lightning will be nearby.

You can sometimes tell how far away a storm is by counting the number of seconds between the time you see a lightning flash and the time you hear the thunder.. Once you know the number of seconds, divide that by 2 to know how many miles away the storm is.

For example: if you counted 10 seconds, you can divide it by 2 and estimate the storm is about 5 miles away.


When lightning passes through air, it heats it to thousands of degrees. This causes the air to expand rapidly producing a shockwave and sound which is called thunder. Thunder is not dangerous but it is possible if the strike is close enough that the shockwave could break windows.
Lightning is the main danger. The safest place is indoors or in a vehicle. Indoors you should stay as far as possible away from plumbing, electric wiring and chimney breasts as lightning could possibly track down along the damp flues. If you need to make calls, use your cell phone instead of the landline.
A vehicle is safe not because of the insulating rubber on the tyres , but because the lightning will travel down to earth through the skin of the vehicle instead of through the internal space.
If caught outside, don't stand under trees, and if you are in an open space such as a field or golf course, the best thing to do is crouch down in the lowest spot in the area you can find.


Yes, because lightning can damage power lines and more sensitive electronic equipment.

Damage caused by lightning strikes were divided in two:
1. Damage caused by direct lightning. This damage is immediately easy to know why, because lightning struck a building and at the same time the existing electronic equipment were damaged in the indication.
2. Damage caused by indirect lightning. This damage is difficult to identify clearly because of lightning that grabbed at one point locations so that the conducting induction through the flow of electricity, telecommunications, iron pipes and other equipment can reach 1 km from the lightning occurs. So without realizing suddenly electronic equipment that supports human activity on fire for no apparent reason.

Thunder is the sound produced due to the convergence of positive and negative ions in the cloud.
The occurrence of thunder does not mean there is lightning.


Thunder is the noise created by lightning, so if you're hearing thunder the lightening has already struck as sound travels slower than light. We see the flash of lightning and then hear the crack or rumble of thunder.

The sound of thunder itself cannot hurt you; sound waves, at that decibel level, do not cause damage to humans.

But it can warn you that a lightning strike has already occurred and there is the possibility there may be more happening and to seek shelter. While not all lightning strikes the ground, there's no use tempting fate by being in an unsafe position, such as under a tree or in an open area where you are the highest object.

For the year 2008, death by lightning world-wide was estimated at 24,000, with 240,000 injuries caused by lightning strikes. Lightning most often causes power outages when it strikes power poles, sub-stations, transformers or other electrical generating equipment.


Thunder means lighting, since thunder is the noise created by lighting.

Dangerous, not really. unless you hug your roof antenna.
if you're outside, stay away from trees and you're also not suppose to go swimming since water is conductive. but that last one i've done and nothing happened ;)

Personally, i love thunderstorm, and I'm always the 1st one outside to try to take a picture of a lighting strike.

Sometimes you hear story of people who got struck by lighting, and it's interesting to see that they survive, of course they get burnt.


Thunder is not as dangerous as lightning, because it is just sound, the effect will influence our ears. But lightning, it is very dangerous, because it can strike the objects on land directly, moreover the objects which can be used as conductor, for example metal and water. It is suggested to remain inside home when there is thunder and lightning, and don't turn on any electricity tools. There is always thunder after lightning because sound travels much
more slowly than light. Just stay at home for the safety when there is thunder and lightning in your area.
