Being about 28 million years old, rocks from great distances have been juxtaposed against rocks from very different locations and origins. While the southern section of the fault and the parts through Parkfield experience earthquakes, the rest of the central section of the fault exhibits a phenomenon called , where the fault slips continuously without causing earthquakes. Relatively few communities lie directly along the Garlock, as it is primarily situated in the desert, with , , , and being the closest to it. The width of a fault zone can be less than a mile wide Olema Trough or many miles across Salton Trough. And by using a thin red line, the underlying landscape features are minimally obscured.

Two of them meet in California, and that chasm is what we call the San Andreas fault. This has led to the formation of the Transverse Ranges in Southern California, and to a lesser but still significant extent, the the location of the in 1989.

Research has pinned the interval between significant ruptures on the Garlock as being anywhere between 200 and 3,000 years, depending on the segment of the fault. Following the , Lawson concluded that the fault extended all the way into southern California. Geologists divide it into several segments, each with its own distinct behavior. Major downtown buildings like the Ferry Building see image , well designed by contemporary standards, came through the shaking in good condition. He was the first to realize that the geologic fault actually extended all the way into Southern California, and he also identified a number of associated faults, such as the Hayward Fault. But smaller magnitude earthquakes can also cause damaging levels of ground shaking. Articles about volcanoes, volcanic hazards and eruptions past and present.
