WebA focal mechanism, or "beachball", is a graphic symbol that indicates the type of slip that occurs during an earthquake: strike-slip, normal, thrust (reverse), or some combination. It also shows the orientation of the fault that slipped. WebSep 11, 2024 · Richard Styron. One of the major annoyances of working in earthquake and tectonic sciences is the difficulty of browsing earthquake focal mechanism 'beachball' data, and plotting it in GIS. The typical way of displaying this data spatially is to use a script in Matlab (probably using bb.m ), Python (using the fantastic ObsPy) or the venerable GMT.
