D Focal Mechanisms is a tool for viewing earthquake focal mechanism symbols three dimensionally. This tool operates within the Environmental Systems Research Institute ESRI GIS software Arc. Scene 9. x. The program requires as input a GIS point dataset of earthquake locations containing strike, dip, and rake values for a nodal plane of each earthquake. Other information, such as depth and magnitude of the earthquake, may also be included in the dataset. By default for each focal point, 3. DFM will create a black and white sphere or beach ball that is oriented based on the strike, dip, and rake values. If depth values for each earthquake are included, the focal symbol will also be placed at its appropriate location beneath the Earths surface. D Velocity Modeling. Author Cliff Thurber.
