Lightning strikes are one of the most devastating natural forces known to mankind, not only to humans but to electrical equipment, and down time to business overall.

Most of the damages to buildings and equipment are due to unprotected structures that causes potential differences between two or more conductors being a good or a bad conductor and ground. This can course a side way flash and can be very dangerous to personal and electrical equipment.
 
Direct strikes to a building can damage the structure such as roof tiles and trusses. It is not common but damage to brick walls and concrete flooring has been reported from time to time. The thermal effect of a direct lightning strike can heat up some materials and the possibility of a fire is enhanced.

Direct lightning strikes on power lines or telecom lines can have devastating effects to all users of power or telecom lines. Ones lightning strikes a power line the current will run in both directions and will dissipates into the grid. Ones in the grid it can run for tens of kilometers and leave a path of destruction in its wake.

A nearby strike will not only change the potential between  connected systems, but the static induction will induce all electrical conductors and damage although not that severe as a direct hit.

When lightning hit the ground, tree, lightning conductor ext it is not all over. All that power goes to ground and dissipate; all conductor of electricity will be induced for as far as five kilometers. The result will be the same as direct strikes only the current wont is so intensive. The same protection must be in place for this action, and once you have a lightning conductor fitted or are close by one, the chances to contract this action is far greater than other wise.
