Focal Mechanisms Explained: What are those “beach balls”? (Educational)

www.iris.edu/earthquake for more intro animations
Focal mechanisms are released after an earthquake to show what type of Earth movement produced the earthquake. These are typically shown using a so-called "beachball" diagram. They refer to the orientation of the fault plane that slipped and the slip vector, and are also called fault-plane solutions.

I think if I watch this 25 times I may get it. Well done, Butler, Johnson, Groom, and Blakley.
