Current Earthquake Information. Fault trace visible as a line of trees above the orange grove east of Hemet, CA along State 74. While most of the major fault lines have some surface expression here, there are many that do not. These faults can also produce large earthquakes, such as the M6.7 Reseda/Northridge Earthquake of January 17, 1994.

The fault dimensions (length and width) and the amount of slip vary dramatically across the spectrum of earthquake magnitudes.
