Fault lines in northern california.

Owing to wiggles in the fault line, portions of the thin red lines can be more than 100 ft from the fault. By presenting the San Andreas Fault map as interactive web-based imagery, anyone can pinpoint the fault anywhere along its trace. And by using a thin red line, the underlying landscape features are minimally obscured.The California Integrated Seismic Network and the U.S. Geological Survey reported today that a magnitude 6.4 earthquake struck 3 miles offshore in Northern California on December 20, 2022 at 2:34 am local time (December 20 10:34 UTC) at a depth of 11 miles (18 kilometers).

northern boundary is the linear east-west trending Gorda escarpment [e.g., Leitner et al., 1998, and references therein]. The tectonic history of the Vizcaino block is controversial with little consensus on its original location on the margin, the past location of the San Andreas or equivalent faults, or timing of deformation [e.g., McLaugh-The transform faults are faults were the motion is mostly horizontal, they happen often in the ocean ridge. It´s when two plates move horizontally from eachother and that causes a fault, one of the most known transform fault is the fault of San Andreas, in California, but most of this kind of faults occur on the ocean basis.The 1906 earthquake ruptured the northernmost 296 miles (477 km) of the San Andreas Fault between San Juan Bautista and Cape Mendocino.

The San Andreas fault today has locked and creeping segments along its approximately 800 mile (1300 km) length in California. The 1906 earthquake ruptured all locked segments of the fault in northern California. The amount of horizontal slip, or relative movement along the fault, varied from 2 to 32 feet (0.5 m to 9.7 m).That is why we can have an earthquake on the SAF in northern California but not on the SAF in southern California.
