Lightning conductors are the devices used to protect buildings from the effect of lightning. It is a metallic rod, taller than the building, installed in the walls of the building during its construction. One end of the rod is kept out in the air and the other is buried deep in the ground. The rod provides easy route for the transfer of electric charge to the ground.

Since, in seismic zones, all the houses and buildings should be designed and constructed in such a way, so that they can withstand major earthquake tremors.

Earthquake-prone to some states of India are as follows:
(i) Kashmir
(ii) Gujarat
(iii) Rajasthan.

When we touch a charged body, it losses its charge, due to the process of earthing. As our body is a good conductor of electricity and transfers the charges to the earth.

Earthing helps to transfer unwanted electric charges in electrical circuits to flow to earth and in this way it prevents the electrical equipment from damage.

Thunderstorm, lightning and cyclones are the natural phenomena that can be predicted.

We get conclusion from this observation that the object has an electric charge on it.

Protections against earthquake :
Earthquakes cannot be predicted. They can be highly destructive. It is, therefore, important that we take necessary precautions to protect ourselves all the time. It is advisable to make the structure 'Quake Safe'.
(i) Consult qualified architects and structural engineers.
(ii) In highly seismic area, the use of mud and timber is better. They keep roofs light.
(iii) Fix shelves and cupboards to the walls.
(iv)Be careful where you hang wall clocks, photo frames, water heaters etc.
(v) Building can catch fire during earthquake. So all buildings must have fire fighting equipments in working order.
In the event that an earthquake does strike, take the following steps to protect yourself.
At home: Take shelter under a table, stay away from tall and heavy objects and if you are in bed, do not get up. Protect your head with a pillow.
Outdoors: Find a clean spot, away from buildings, trees, and overhead power lines. Drop to ground. If you are in car or bus do not come out.

It is not safer to use wired telephone during lightning because at that time lightning can enter the wire of telephone, if open somewhere, that is if there is any cut in the wire. On the other hand, there cannot be any possibility of this type in wireless telephone.
