Earthquakes are an extremely common occurrence around the Salton Sea, and in Salton City, due to dozens of fractured fault lines that run through Imperial County. Salton City is also mere miles from major, destructive fault lines, such as the Imperial Fault, the San Andreas Fault, and the San Jacinto Fault. The Superstition Faults also pose a major risk to the area, as well as the Brawley Seismic Zone, which produces frequent yet mostly non-damaging earthquake swarms. At certain times, this area can experience dozens of felt earthquakes in a time period lasting from one day to over one week. Most of the earthquakes are minor to moderate and pose no hazard due to strict seismic codes; however, the area is notorious for earthquake swarms and other major seismic events. The San Andreas Fault begins at Bombay Beach where the southern terminus of the San Andreas transitions into the Brawley Seismic Zone, about ten miles across the Salton Sea from Salton City. Most residents are fully accustomed to minor and moderate earthquakes, but are prepared for a large one.
