California's Earthquake History. Although earlier earthquakes have been documented—such as significant movement on the southern San Andreas fault all the way back to the 1600s—the earliest reported earthquake in California was on July 28, 1769, noted by members of a Spanish expedition to chart a land route from San Diego to … Southern California. Four EDM networks located in Southern California show strain accumulation on the San Andreas fault system in this region. This map shows the locations of 4 two-color EDM (Electronic Distance Meter) networks in Southern California. These networks are radial with approximately 12 baselines using a common, central station. Brown lines are known hazardous faults and fault zones. Magnitude = ? for new earthquakes until a magnitude is determined (takes 4-5 minutes).

A fault is a three-dimensional surface within the planet that might extend up to the surface or might be completely buried. In contrast, a fault line is where the fault cuts the Earth's surface… if indeed it does. The most prominent faults in each state are usually shown on a state's geologic map as black lines.October 6, 2016 11:22 AM EDT.
