Earthquake effect

  1. Dec 3, 2008 #1
    I have a question regarding the production of an effect similar to that of an earthquake.

    Let's presume that it's in a large area. It's moving. Like, for example, a train.

    If a force where to applied in a single point, of the size of a tennis ball, would it be possible to cause the "train" to vibrate, or would the tennis ball just go through the area ? I believe that if it were possible to cause the molecules of the material to ressonate, it might cause an effect of an earthquake. But I'm not entirely sure.

    Could some elaborate on the possibilities ?

    Much appreciated.
