Rule 5 Woodsterman Style or Earthquakes

For us who are not Seismologists or Geophysicists.

Read and learn! Recently, Japan experienced a devastating 8.9 intensity earthquake.
 
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 prudent to let everyone know the difference. 
 
What's the difference between an oscillatory and a trepidatory earthquake?

1.  This calculation is just for engineers:
 
 
2. And this one is for laymen -- like  you:
 
This  is a trepidatory earthquake -- an up and down  movement.....

  This  is an oscillatory earthquake -- a side to side  movement...

And this is a combination of both trepidatory and oscillatory:
ISN'T SCIENCE BEAUTIFUL WHEN 
PROPERLY EXPLAINED ?

Thanks Dan !
