The Hayward Fault is the single most urbanized earthquake fault in the United States—in 1868 there were only 24,000 residents living in Alameda County; now there are more than 2.4 million people. South of the Bay Area the Hayward and Calaveras merge into the San Andreas. Calaveras Fault. Data from the USGS shows the quakes were widely felt by people in . For the most up-to-date information, please refer to the interactive fault map. Take the Kestrel Trail to the Sierra Vista Trail north-east, then south to the Lower Calaveras Fault Trail with its great views of Alum Rock Canyon and Alum Rock Park. They found a correspondence between the areas that slipped in moderate earthquakes with areas that were relatively devoid of micro-earthquake activity. Tests for an example streak of 243 earthquakes demonstrate that relative arrival times with normalized cross correlation coefficients as low as 70%, interevent separation distances as large as to 2 km, and magnitudes up to 3.5 as recorded on the . The San Andreas Fault, the largest active fault in California, was the source of the San Francisco 1906 magnitude 7.9 earthquake and the 1989 magnitude 7.1 (Loma Prieta) earthquake and is 16.9 kilometers from the SVRTC. QUESTION. . 4 answers. The San Andreas Fault and 6 other significant fault zones are present in the Bay Area: the Calaveras, Concord-Green Valley, Greenville, Hayward, Rodgers Creek, and San Gregorio Faults. Calaveras Fault creep in downtown Hollister in April 2009. of the Calaveras Fault remains uncertain [WGCEP, 1999]. Hundreds of homes and other structures are built along the fault trace, and mass transit corridors, major freeways, and many roadways cross it at . The closest active fault to the plan area is the San Andreas Fault, located about 2,000 feet southwest of the southwestern plan area boundary. Looking at patterns of activity in the San Francisco Bay Area since 1948, we find an increase of activity on the Calaveras fault near San Jose beginning in the 1980s which, if our model is relevant, would forecast a large earthquake in that region. The Anderson Reservoir lies atop the Calaveras fault, a major leg of the San Andreas Fault system. . Each region is characterized by a constant rate of seismic slip as computed from earthquake magnitudes . Specifically, a 1998 report prepared by Geomatrix found evidence of activity during the Late Quaternary on this fault system within the Walnut Lower Calaveras Fault Trail is a 3 mile moderately popular blue singletrack trail located near San Jose California. Cove, Maacama, West Napa, Green Valley, Concord, Greenville, and Calaveras faults. All of these are ``right-lateral strike-slip faults'', which means that the motion is predominantly horizontal, with the land on the West side of the fault moving North. [1990] studied microearthquake activity of the Calaveras Fault in great detail. The first study area contains the rupture area of the M6.2, 1984 Morgan Hill, and the latter is adjacent the southern end of the M7.1, 1989 Loma Prieta rupture. The fence line at Point Reyes, which still shows the shift from the quake almost 110 years ago, lies directly on the San Andreas Fault, the "host" of the . We have prepared a finite-source inversion of the Alum Rock earthquake using the method of Dreger and Kaverina (2000). Faults active in the Quaternary (2.6 Ma) were digitized from their original sources in order to preserve as much of the original detail as possible. date, our crews have installed 500 feet of the new steel pipe, welded the joints, Significant earthquake activity occurred on both east- and west-Bay faults in the ten or so years before the 1868 east- M 5.6 Calaveras fault . The quakes were all centered along the Calaveras fault system, which is located in the hills east of the San Francisco Bay Area. The Calaveras fault is a major offshoot of the San Andreas fault in Northern California. 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. and of these, only a few are associated with historic earthquake activity. In addition to rupture in moderate earthquakes, this section of the Calaveras Fault has been extraordinarily active in microearthquake activity. Other nearby faults includes Greenville (9.5 miles east of the project site), and San Andreas (28 References As of January 12, 2017, the USGS maintains a limited number of metadata fields that characterize the Quaternary faults and folds of the United States. Credit: modified from Scott et al. The most active fault in the region is the San Andreas Fault; however, all of the large faults in the San Francisco Bay region that display recent earthquake activity, or that display Quaternary offset, are part of the greater San Andreas Fault System. We plan to connect the new 78 inch pipe to the existing pipes within the existing dam this Fall 2016. If that is the case, the longer fault system could produce larger temblors. [1] The similarity of seismograms recorded by two seismic stations demonstrate that the 31 October 2007 moment magnitude M5.4 Alum Rock earthquake is a repeat of a 1955 ML5.5 earthquake. Submit one here. As described in this report, the Hayward fault zone is a zone of highly deformed rocks which trends north 30 degrees west from an area . Both occurred on Oppenheimer et al.'s (1990) Zone V "stuck patch" on the central Calaveras fault, providing new support for their model of Calaveras fault earthquake activity. They also found that small earthquakes All of these are ``right-lateral strike-slip faults'', which means that the motion is predominantly horizontal, with the land on the West side of the fault moving North. A major reason why activity along the Calaveras Fault deserves close attention is because the USGS gives it has the second highest probability of rupturing in a large magnitude (M≥6.7) by 2043. These faults are featured on the following maps: Mojave Fault Map Southern Fault Map Los Angeles Fault Map Quaternary Fault and Fold Database of the United States. 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 1984 Morgan Hill event and the last moderate earthquake was the 2007 Alum Rock event. In the San Andreas and the Calaveras catalogs, where the return of the seismicity rate to the background level is well resolved, we find that the return to the background in the distance range of 1-2 rupture radii from a previous earthquake is preceded by a period during which the seismicity rate falls about 30% below the background rate . Problems with Internet Explorer? Past the Historic Ranch House and Penitencia Creek, there is a rapid elevation gain along the Lower Calaveras Fault Trail, through gray pine habitat, and dramatic views of Alum . of the Calaveras Fault remains uncertain [WGCEP, 1999]. ML < 4) earthquakes on two 10-km segments of the Calaveras fault between Calaveras and Anderson reservoirs follows a simple linear pattern of elastic strain accumulation and release. The 1989 Loma Prieta earthquake occurred on the San Andreas fault within 30 km of the section of . Past the Historic Ranch House and Penitencia Creek, there is a rapid elevation gain along the Lower Calaveras Fault Trail, through gray pine habitat, and dramatic views of Alum . Fault Activity Map of California. The long-term slip rate on the Calaveras Fault to the south of where the Hayward Fault splays from it is thought to be 15 ± 3 mm/yr [Working Group on California Earthquake Probabilities , 1999]. The San Andreas Fault, the largest active fault in California, was the source of the San Francisco 1906 magnitude 7.9 earthquake and the 1989 magnitude 7.1 (Loma Prieta) earthquake. However, for the line-source parallel with the Calaveras fault (model shown in Figure 2.49 (upper part of bottom image)), most of the slip lies to the southeast of the epicenter. Adding the Calaveras to that would raise the magnitude to roughly the same size as the 1906 earthquake on the San Andreas fault. Another large and active named segment is the Clark fault, which runs from near Hemet to just 15 km southwest of the shore of the Salton Sea. Indonesia, an archipelago of more than 270 million people, is prone to earthquakes and volcanic activity because it sits along the Pacific "Ring of Fire," a horseshoe-shaped series of fault lines. Upper Calaveras Fault Trail is a 2 mile moderately popular blue singletrack trail located near San Jose California. [3] Oppenheimer et al. The white lines indicate faults recognized by the USGS. UC Berkeley reports that there is potential for larger earthquakes in the San Francisco Bay Area due to the direct connection between the Hayward and Calaveras faults. The USGS continuously monitors their activity. With appropriate browser settings the "live" maps will also show all of the names of faults shown on the map as you rollover with the cursor. The largest historical quake on the Calaveras fault was a magnitude 6.6 temblor in 1911, according to Ross Stein, chief executive of Temblor.net and a former USGS research geophysicist. this fault passes approximately 0.4 miles east of the site) it has not been placed in an A-P Zone. No description for Upper Calaveras Fault Trail trail has been added yet! The Calaveras Fault is located approximately 17 km west of LLNL, and recently active strands of the Greenville Fault Zone are located approximately 1.1 km northeast of the laboratory. The Calaveras Fault, a main component of the San Andreas System, recorded earthquakes of magnitude 5.9 in 1979 and 6.2 in 1984. Take the Kestrel Trail to the Sierra Vista Trail north-east, then south to the Lower Calaveras Fault Trail with its great views of Alum Rock Canyon and Alum Rock Park. The San Andreas fault is the . The fence line at Point Reyes, which still shows the shift from the quake almost 110 years ago, lies directly on the San Andreas Fault, the "host" of the . They also found that small earthquakes The red line is the newly discovered surface trace connecting the southern end of the Hayward Fault to the Calaveras Fault, once thought to be an independent system. "In terms of day-to-day microactivity, it's the most active fault in the San Francisco Bay area . Significant seismic activity can be explained by repetitive failure of the same fault areas in nearly identical earthquakes. . According to the CGS, the nearest active faults are the Calaveras fault (2.25 miles southeast of the project site), Concord fault (4.75 miles northeast of the project site), and Hayward fault (8.5 miles southwest of the project site). Measuring fault motion from a shifting landscape Geologic evidence demonstrates Holocene activity along strands of the Las Positas Fault Zone that lie about 90 m southeast of LLNL at their point of closest approach. As of July 2015, the project is 67% complete. The San a fault creep along the Calaveras Fault. Occurrence of small (3 ⩽ M L < 4) earthquakes on two 10-km segments of the Calaveras fault between Calaveras and Anderson reservoirs follows a simple linear pattern of elastic strain accumulation and release. (2020). References. [3] Oppenheimer et al. According to the 1999 study on earthquake probabilities in the San Francisco Bay Area, the Calaveras fault has an 18% probability of a M6.7 or higher earthquake in the next 30 years. The correlations of seismic activity and fault-trace characteristics are similar to those for shocks along the creeping section of the San Andreas Fault in central California and suggest that the specific "stuck" and "creeping" patch model of Bakun et al. What is the difference between brittle and plastic (elastic) deformation and how do these concepts apply to earthquake activity with increasing depth? The Calaveras Fault, where Tuesday's earthquake originated, is not far from the Hayward Fault. The probability given, 26%, is only behind the nearby Hayward Fault, which has a 33% chance of rupturing. It is part of the tectonic boundary between the Pacific and North American plates. The Calaveras Fault, a main component of the San Andreas System, recorded Damages from such a quake might reach $300 billion. report feeling earthquake activity and tour interactive fault maps in SFGATE's . As of July 2015, the project is 67% complete. The correlations of seismic activity and fault-trace characteristics are similar to those for shocks along the creeping section of the San Andreas Fault in central California and suggest that the specific "stuck" and "creeping" patch model of Bakun et al. The Bay Area fault system and the spot (red star) where the Hayward Fault branches off from the Calaveras Fault. This curb in Hollister has shifted to the right, due to the steady creep of the Calaveras Fault (Photo by: Horst Rademacher) The main difference, of course, is the distance from the epicenter. Calaveras Fault; Concord Fault; For recent activity in the region shown on this map see the USGS map for this location. The Calaveras and San Antonio reservoirs are part of the Hetch Hetchy water system, an improbable Rube Goldberg-like scheme to move water from the Sierra Nevada across the Central Valley, across the Calaveras Fault, across the Hayward Fault, across the liquefaction-vulnerable marshes of the southern bay, then into two long, linear sag ponds . We examine the spatial distribution of earthquake hypocenters in four central California areas: the aftershock zones of the (1) 1984 Morgan Hill (2) 1979 Coyote Lake, and (3) 1983 Coalinga earthquakes, as well as (4) the aseismically creeping area around Hollister. The centers of these independent patches of earthquake activity are 20 km apart. Based on present creep rates, the fault can be divided into two overall segments; that south of the Calaveras Reservoir, and the San Ramon segment (Kelson, et al, 1992), between Sunol and Danville. Looking at patterns of activity in the San Francisco Bay Area since 1948, we find an increase of activity on the Calaveras fault near San Jose beginning in the 1980s which, if our model is relevant, would forecast a large earthquake in that region. The Hayward fault last produced a large quake (M6.8) in 1868. the present-day seismic hazard to the Bay Area from the Hayward is: . The centers of these independent patches of earthquake activity are 20 km apart. This multi-use trail can be used both directions and has a moderate overall physical rating with a 1,057 ft green climb. Occurrence of small (3 ??? In the San Andreas and the Calaveras catalogs, where the The northern section of the Calaveras fault ruptured in a ~M6 earthquake in 1861, and surface rupture was observed over a distance of 13 km. 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 1984 Morgan Hill event and the last moderate earthquake .

The 1989 Loma Prieta earthquake occurred on the San Andreas fault within 30 km of the section of . Map showing the creeping section of the San Andreas Fault between Los Angeles and San Francisco. The San Andreas fault the world's most closely watched earthquake zone will be the subject of a special three-day conference at Stanford and the United States Geological Survey (USGS) next week. (1980) developed for the San Andreas is applicable to the creeping Calaveras Fault . fault location and activity levels, ground composition, materials). an 1868 magnitude 7 earthquake. Because the landscape has not been modified by human activity, it still preserves many of the natural landscape features associated with active strike-slip fault zones. Several studies have observed changes of seismic velocity due to earthquakes or volcanic activity by using multiplet earthquake analysis (14, 15), controlled source experiments (5, 16), and seismic interferometry (1-3, 7, 8, 11, 17, 18).Although seismic velocity variation between several seismometer pairs has been reported using these approaches, temporal variation of seismic velocity along . A detailed kinematic study of fault slip occurring from the surface to a depth of about 7 km on the Calaveras fault north of Hollister was conducted during the summer of 1977. The Calaveras Fault has a MCE of 7.0 and also probably a 23 percent probability of occurrence in the next 30 years (Working Group on California Earthquake Probabilities, 1990). 1897 06 20 - Calaveras fault, California - M 6.3 1915 06 23 - Imperial Valley, California - M 6.3 1992 06 28 - Big Bear, California - M 6.5 (1980) developed for the San Andreas is applicable to the creeping Calaveras Fault . Each region is characterized by a constant rate of seismic slip as computed from earthquake magnitudes . (e.g. and of these, only a few are associated with historic earthquake activity. The quake happened at a depth of around 4 miles (6.5 km) on the infamous San Andreas Fault, close to a region where the Calaveras Fault branches off. Geographic coordinates: -120.17428, 37.54117 (WGS84) Location accuracy: 100 (meters): Relative position: The Mount Gaines Mine is approximately 12 miles west-northwest of the town of Mariposa. This curb in Hollister has shifted to the right, due to the steady creep of the Calaveras Fault (Photo by: Horst Rademacher) The main difference, of course, is the distance from the epicenter. The U.S. Geological Survey says that an end-to-end rupture of the Hayward fault would cause an earthquake of magnitude 7.5. The USGS continuously monitors their activity. These . The 1989 Loma Prieta earthquake occurred on the San Andreas fault within 30 km of the section of . The Calaveras and Hayward faults extend up the east side of the San Francisco Bay. Earthquake properties were examined along two northern California fault segments, one is the Calaveras fault, another is a northern segment of the San Andreas fault. Similar to the 1994 Fault Activity Map, the 2010 map is accompanied . . The 1954 San Jacinto earthquake probably occurred due to rupture on the Clark fault. It splits from the San Andreas Fault around Hollister and produced the Calaveras Valley. The faults shown here are represented by simple lines which do not convey how complicated they can be. a.the calaveras fault b.the hayward fault c.the san andreas fault d.both B and C e.all of A to C. . Looking at patterns of activity in the San Francisco Bay Area since 1948, we find an increase of activity on the Calaveras fault near San Jose beginning in the 1980s which, if our model is relevant, would forecast a large earthquake in that region. The most active fault in the region is the San Andreas Fault; however, all of the large faults in the San Francisco Bay region that display recent earthquake activity, or that display Quaternary offset, are part of the greater San Andreas Fault System. South of the Bay Area the Hayward and Calaveras merge into the San Andreas. The USGS says there is a 26% chance of a magnitude 6.7 or higher earthquake on the Calaveras Fault in the next 30 years, only a slightly lower chance the anticipated "Big One" on the Hayward . If the level of earthquake activity during the next few decades is similar to activity between 1836 and 1911, then the probability of a magnitude 7 earthquake in the next 30 years is about 75 percent. The faults shown here are represented by simple lines which do not convey how complicated they can be. Understanding Earthquake Hazards in the Bay Area. The Calaveras Fault (123 km; 76 miles) passes through or by Hollister, Gilroy, San Jose, Milpitas, Pleasanton, Dublin, San Ramon, and Danville. fault segments and find that the seismicity rate following a mainshock decays ap-proximately as 1/time, the duration of the aftershock activity seems to be independent of distance from the mainshock, and the seismicity rate at lag times of up to about 100 sec is nearly constant.
