This paper presents a new method for displaying focal mechanisms - plotting them on a ternary graph or 'triangle diagram' where the vertices represent normal, thrust, and strike-slip focal mechanisms. This method also provides a natural way for determining the relative proportions of thrust, normal, and strike-slip motion for any particular earthquake focal mechanism. ?? 1992.
