Earthquake beach ball diagrams

Webing black and white quadrants. This sphere looks like a beach ball, and sometimes a figure showing focal mechanisms is referred to as a “beach ball” diagram. The black quadrants represent areas that moved away from the earthquake’s hypocen-ter, whereas the white quadrants represent areas that moved toward the earthquake’s hypocenter.
