Full Description

This capability can be used to display event location information from the S minus P epicenter location method for the user-defined event. Associated with the station locations, an inferred epicenter-to-station distance can be entered for each station. If entered, the station locations will be displayed with a triangle symbol, the 3- or 4-letter station code (for the station name) will be displayed adjacent to the triangles, the event location will be displayed with a star symbol, and the epicenter-to-station distances will be used to display circles around each station indicating the possible location of the epicenter based on each station’s data.
