Map of earthquakes (black dots, scaled by magnitude) from the Brawley Seismic Zone spanning 1981 to 2916. The beachballs tell seismologists which way a fault moves during a larger earthquake. The larger events labeled here are the 1981 Westmoreland quake, the 1987 Elmore Range and Superstition Hills earthquakes (green), the 2005 Obsidian Butte event (yellow), the 2012 Brawley quake (purple) and the 2001, 2009 and 2016 Bombay Beach quakes (red).
