Another fault further north, the Maacama Fault, is also considered to be part of the "Hayward Fault subsystem". [5] [6] While the San Andreas Fault is the principal transform boundary between the Pacific Plate and the North American Plate, the Hayward-Rodgers Creek Fault takes up its share of the overall displacement of the two plates.
1969 Santa Rosa earthquakes. At 04:56 and 06:19 UTC on October 2, 1969 (21:56 and 23:19 PDT October 1), a pair of earthquakes of magnitude 5.6 and 5.7, respectively, struck the city of Santa Rosa, California, killing one person and damaging buildings. The maximum felt intensity for the two events was VII (Very strong) and VIII (Severe ...
Calaveras Fault. The Calaveras Fault is a major branch of the San Andreas Fault System that is located in northern California in the San Francisco Bay Area. Activity on the different segments of the fault includes moderate and large earthquakes as well as aseismic creep. The last large event was the magnitude 6.2 1984 Morgan Hill event.
The Healdsburg Fault is a seismically active geological feature associated with the Santa Rosa Plain and the Alexander Valley, in Sonoma County, California, United States. The eastern sides of these floodplains are bounded by strike-slip or transform faults. The maximum credible earthquake expected to be generated from the Healdsburg Fault is ...
A fault scarp at Fairview Peak after the M w 7.3 shock on December 16. On December 16 at 3:07a.m. PST , [ 16 ] the largest earthquake in the sequence, the M w 7.3 earthquake was triggered by oblique-slip displacement along the Fairview Peak , West Gate and Gold King Fault, and Louderback Mountain Faults for a total length of 100 km, of which 14 ...
Highlighted in purple are the San Andreas Fault (left) and Santa Monica Bay complex (right). The foreground is in the Santa Barbara Channel , the east-trending zone marks the Transverse Range . Faults in the upper left are part of the Eastern California Shear Zone, connecting northward with the Walker Lane region.
The 1959 Hebgen Lake earthquake (also known as the 1959 Yellowstone earthquake) [4] occurred in the western United States on August 17 at 11:37 pm (MST) in southwestern Montana. [4][5] The earthquake measured 7.2 on the moment magnitude scale, [1] caused a huge landslide, resulted in over 28 fatalities and left $ 11 million (equivalent to $115 ...
Map showing the San Jacinto Fault Zone outlined in red. The San Jacinto Fault Zone (SJFZ) is a major strike-slip fault zone that runs through San Bernardino, Riverside, San Diego, and Imperial Counties in Southern California. The SJFZ is a component of the larger San Andreas transform system and is considered to be the most seismically active ...
