  2. Hayward Fault Zone - Wikipedia

    en.wikipedia.org/wiki/Hayward_Fault_Zone

    The Hayward Fault is parallel to the San Andreas Fault, which lies offshore and through the San Francisco Peninsula. To the east of the Hayward Fault lies the Calaveras Fault. In 2007, the Hayward Fault was discovered to have merged with the Calaveras Fault east of San Jose at a depth of 6.4 kilometers (4.0 mi), with the potential of creating ...

  3. Claremont Tunnel - Wikipedia

    en.wikipedia.org/wiki/Claremont_Tunnel

    The tunnel crosses the Hayward Fault at a nearly perpendicular angle 850 feet (260 m) from its western portal, and creep along the fault resulted in an offset of 13 inches (330 mm) by 2008. [6] The maximum credible earthquake (magnitude 7.0) predicted in studies would cause an offset of 7.5 feet (2.3 m).

  4. UCERF3 - Wikipedia

    en.wikipedia.org/wiki/UCERF3

    A major achievement of UCERF3 is use of a new methodology that can model multifault ruptures such as have been observed in recent earthquakes. [5] This allows seismicity to be distributed in a more realistic manner, which has corrected a problem with prior studies that overpredicted earthquakes of moderate size (between magnitude 6.5 and 7.0). [6]

  5. Series of small earthquakes shake Bay Area near Hayward fault

    A magnitude 3.7 earthquake shook the Bay Area city of Hayward just before 2 p.m. Thursday, according to the U.S. Geological Survey. The temblor followed three earlier small earthquakes — a ...

  6. Aseismic creep - Wikipedia

    en.wikipedia.org/wiki/Aseismic_creep

    In geology, aseismic creep or fault creep is measurable surface displacement along a fault in the absence of notable earthquakes. Aseismic creep may also occur as "after-slip" days to years after an earthquake. Notable examples of aseismic slip include faults in California (e.g. Calaveras Fault, Hayward Fault, and San Andreas Fault).

  7. Lawson Adit - Wikipedia

    en.wikipedia.org/wiki/Lawson_Adit

    The Lawson Adit is a horizontal mine tunnel, or adit, on the UC Berkeley campus, near the Hearst Mining Building, dug directly through the Hayward Fault. [1] Started in 1916, the adit is named after Andrew Lawson , one-time Dean of the College of Mining at UC Berkeley.

  8. Maacama Fault - Wikipedia

    en.wikipedia.org/wiki/Maacama_Fault

    The Maacama Fault is a right lateral-moving (dextral) geologic fault located in the Coast Ranges of northwestern California.It is considered to be the northernmost segment of the Hayward Fault subsystem of the San Andreas Fault zone.

  9. 1979 Coyote Lake earthquake - Wikipedia

    en.wikipedia.org/wiki/1979_Coyote_Lake_earthquake

    The San Andreas Fault system (SAF) is a network of right-lateral strike-slip faults that form a portion of a complex and diffuse plate boundary. The faults span on and off shore along the California portion of the Pacific Rim, and in the area near San Francisco Bay, the extent of the various fault strands are limited to about 80 kilometers (50 mi) wide from east to west.
