During a lightening strike, when an individual is in a house 8 miles away then he will be safe.
This is because house is a closed shelter so lightening cannot enter inside the house unless and until the windows or doors are open.
Whereas a tent cannot be safe during lightening strike as tent is made up of cloth or light weight material. Hence, it does not provide any protection during lightening strike.
