Locations of more than 110 earthquakes (1968-1976) show that the newly mapped fault zones in Monterey Bay are seismically active. This comprehensive imaging helped highlight fault connections, which are important because longer faults can produce larger earthquakes. 7.5 M - Hayward/Rogers Creek Fault 7.1 M - San Gregorio 6.9 M - North Calaveras These magnitudes are given on the Moment Magnitude Mw scale which is currently favored by the seismic community as providing a more consistent measure of energy release in an earthquake. However, the present day Pacific-North America plate boundary is located mostly in the continent, rather than offshore. The Hosgri Fault (also Hosgri Fault Zone, San Gregorio-Hosgri Fault Zone) is an offshore fault zone located near the Central Coast of California in San Luis Obispo County.The main fault stretches for about 87 miles (140 km), and is located nearest to the coastal communities of Cambria, San Simeon, Morro Bay, Baywood Park-Los Osos and Avila Beach. It is a right-lateral strike-slip fault zone oriented generally north-south, comprised of two or more parallel and fairly continuous fault segments that extend at least 100 km from Point Año Nuevo (Weber 1990; Weber et al. USGS mapped the Hosgri fault zone in high-resolution for about 100 kilometers between Piedras Blancas and Point Sal in central California, where the fault runs within 3 nautical miles of the Diablo Canyon Power Plant. Learn how to create your own. The southern part of the system includes the Sur, San Simeon, and Hosgri faults (Hall, 1975; Graham and Dick- inson, 1978). For the most up-to-date information, please refer to the interactive fault map. This zone appears to connect with faults mapped on land near Ano Nuevo Point and Point Sur. The San Gregorio Fault is part of a system of coastal faults which run roughly parallel to the San Andreas. There is a complex pattern of crustal terrains bounded by faults, which are completely or partially kinematically coupled to the Pacific plate [Argus and Gordon, 2001; Becker et al., 2005]. The acoustic character and morph… The San Gregorio fault zone is the northern part of a system of coast-parallel strike-slip faults extending from Point Conception in the south to the Matin Peninsula in the north. Die Verwerfung ist ca. The San Gregorio fault forms part of the San Andreas fault system, a plate boundary that has been accommodating motion between the Pacific and North America plates since the Miocene (Atwater, 1970; Fig. San Gregorio-Hosgri fault zone, California Item Preview remove-circle Share or Embed This Item. That quake was named after Loma Prieta (“dark hill”), the mountain near the quake’s epicenter in the park. The San Andreas Fault’s devastating 6.9 magnitude earthquake caused upheaval throughout Northern California in 1989. It's an area that lies between the infamous San Andreas and the little-known offshore San Gregorio Fault. The San Gregorio Fault runs slightly southeast of park boundaries. EMBED. Die wichtigsten Gräbenbrüche sind der San Andreas Fault, der Rodgers Creek Fault, der Hayward Fault, der Greenville Fault, der Calaveras Fault, der Concord Green Valley Fault und der San Gregorio Fault. It lives in moist montane chaparral The The Palo Colorado-San Gregorio is the major active fault zone within the MBNMS.

We mapped a poorly known 64‐km‐long section of this important fault zone offshore of Big Sur between Piedras Blancas and Point Sur using high‐resolution geophysical tools and methods. Remove maintenance message San Gregorio-Hosgri fault zone [Dickinson et al., 2005]. Advanced embedding details, examples, and help! According to Glen, [11] the Seal Cove fault cuts the cliff face at Moss Beach where it brings horizontal overlying Pleistocene terrace sands into clearly exposed fault contact with the mid-Pliocene Merced Formation. The known faults in the San Francisco area include the San Andreas, the Hayward, the Rodgers Creek and the San Gregorio. Founded in 1906 in San Francisco, the Society now has members throughout the world representing a variety of technical interests: seismologists and other geophysicists, geologists, engineers, insurers, and policy-makers in preparedness and safety.
