Recently Christchurch and then Japan had terrible earthquakes with lots of after-shocks. They were caused by Tectonic plates moving under unbelievable pressure.
Some were thought to be Oscillatory, while others were believed to be Trepidatory. It occurred to me that most people might be confused about this, so I thought it wise to let everyone know the difference.

What's the difference between an Oscillatory and a Trepidatory earthquake ?
1. Now, this calculation is just for engineers. If you are competent in this field, this should explain it.
2. However, this one is for the layman and, having access to your e-mailed offerings in the past, you should get the picture straight away.
This is a trepidatory earthquake -- an up-and-down movement.....
What are friends for ?
Class is dismissed........
