Does lightning strikes the same place twice ?

I heard it from somewhere that lightning can strikes the same place twice, some more than twice. Any scientific explanation?

    If you are referring to when it seems like a lighting bolt strikes one place, fades away for a second, then comes back and strikes that same place again, then yes, lightning can strike the same place twice.

    The reason for this is that there is so much energy built up at the bottom of the storm cloud that the same lightning bolt strikes twice, sometimes even more times. The process begin when a single negative charge (electron) separates from the base of a cloud and begins heading toward the ground. This negative charge is called a "stepped leader".

    Meanwhile, on the ground, positive charges build up and begin moving up to meet the negative stepped leader because as you know, opposite charges attract each other.

    When they connect, a channel is established and more electrons begin flowing down from the cloud. At the same time, a "return stroke" of positive charges emanate from the ground and move upward along the channel.

    The return stroke is what we see as lightning.

    Then, if there is enough of a charge available in the cloud, another negative charge (called a "dart leader") will come down the already established channel and the whole process will occur again, giving some lightning flashes we see a flickering appearance.

    Can lightning strike the same place twice?

    --Lightning does hit the same spot (or almost the same spot) more than once, contrary to folk wisdom. It could be simply a statistical fluke (i.e., with all the lightning that occurs, eventually lightning will strike somewhere near a previous lightning strike within a short period of time). It could also be that something about the site makes it somewhat more likely to be struck. Typically, when lightning strikes something on the ground, the object that is struck sends a faint channel upward that joins the downward developing flash and creates the connection to the ground. Taller objects are more likely than shorter objects to produce the upward channel. But it is also possible that something that locally affects the ability of the ground to conduct electricity (such as the salt or moisture content of the ground at the time, the presence or absence of rock, standing water, pipes or other metal objects in the ground), the terrain shape, the shape of leaves or twigs, or something else might make a particular location more likely than another nearby location to be struck.

    Yes. Lightning can strike any number of times. If it never hit the same place twice... what would be the point of a lightning rod? It wouldn't work.

    yeah I read in a book that lightning strikes the Empire State building about 40 times a year

    Yes,an the little girl from Scary Movie 4 got hit twice.....

    I have a video here ...it only alittle over 1 second long ...but when slowed down it showed that there were four flashs of lightening with in that time space

    yes some towers get hit several times in one storm

    Its not very likely but its not impossible.
