What's Shaken?

We Be Shaken...

Heard on the news this morning that when there is a large earthquake magnitude 5 and over that the earth rings like a bell. They are looking into the possibility that this is a chain of earthquakes each setting off another. We have hundreds of after shocks after any large earthquake however, these seem independent of each other with each having aftershocks for each shake.
