Lightning does occur in different places, but many more times then 2!
Thunder and lightning occur roughly at the same time during a thunderstorm, but they are different things. Typically you see the lightning first and then you hear the thunder.
Lightning not only can strike the same place twice, it frequently does.
Thunder is the sound of the lightening
Many people (not necessarily scientiest or meteorologists) think that lightning will not strike the same place twice. So they say that it is rare for lightning to strick twice, meaning twice at the same place. This term is used to imply something that is rare.
Sheet lightning, or more accurately intracloud lightning is the same as lightning that hits the ground, the only difference is that it is within the cloud. They are no different apart from that. They are the exact same thing, except one would take a different path. They are both dangerous.
you are probably hearing the thunder from a different lightning strike.
after shocks don't occur in the same place due to ex tonic faults occuring in the ground
the same
Myth
Sheet lightning and Heat lightning are very similar, if not the same. They form the same way, but might strike different. For instance, sheet lightning looks more like a sheet in the sky, (strange eh? :D) and doesn't normally strike down into the ground, and when you have heat lightning, you see differently. But mostly, they form the same way. =D good luck!
It is just another myth
Lightning can (and sometimes does) strike twice in the same place. it usually strikes three times in the same place it just apears to be one.
