hayward and san andreas fault

Careful analysis of the age of the earthquakes, including the uncertainties in radiocarbon dating (see Determining the Age of a Paleoearthquake in Introduction to Paleoseismology), showed that the average time between earthquakes is about 100 years. Geographic Names Information System (GNIS), Mapping, Remote Sensing, and Geospatial Data, Earthquake Outlook for the San Francisco Bay Region 2014—2043, Map of active faults and historic ruptures in California, New Information About the San Andreas Fault, Catching Glimpses of Centuries-Old Earthquakes, Science of the New Madrid Seismic Zone - Paleoseismology, UCERF3: A New Earthquake Forecast for California’s Complex Fault System. The plate is moving slowly all the time, but the edges move in fits and starts. As you returned to your home, you would probably see damaged and collapsed buildings and bridges, broken pipes and snapped power lines and scorched remains of fires. The most striking result is that the deformation is not uniformly distributed across the area. A section of sidewalk in Hayward that showed the movement of the Hayward Fault was 'fixed' by the city, much to the dismay of geologists. Investigating Past Earthquakes to Inform the Future. According to a new study, the Hayward fault line that runs under Oakland, California is believed to be more dangerous than the infamous San Andreas fault line that spans Southern California.. The San Andreas and Cascadia fault have a potentially deadlier counterpart lurking in the East Bay region of Northern California. The study concluded that there is 33% likelihood of a surface-rupturing earthquake within the next 30 years. The new San Pablo Bay link between the Rodgers Creek Fault (which extends out of the image to the upper left to Santa Rosa) and the Hayward fault (which joins the Calaveras Fault out of the image to the lower right) is orange. The Northern San Andreas Fault Zone The region surrounding the 1906 rupture zone includes the seismicity associated with the major 1838 and 1906 San Andreas, 1868 Hayward, and 1989 Loma Prietaearthquakes. Workers' Comp RWCC64393236 Posted April 19, 2018, under Blog. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal). For a 12-minute video concerning the Hayward Fault, see the KQED documentary Predictable Peril. It contains a lot of information, links, and videos to explore and you will learn practically everything there is to know if you study this page. But focusing only on avoiding an earthquake doesn’t address most of the effects from the shaking. The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. Here is a shorter eye-opening 7-minute TV clip on the Cascadia Fault. In detail, the fault is a complex zone of crushed and broken rock from a few hundred feet to a mile wide. The Hazel Dell site near Corralitos, CA was trenched in 2013 to characterize the Santa Cruz Mountains section of the San Andreas Fault. The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California. -written by Lisa Wald, Kate Scharer, and Carol Prentice, U.S. Geological Survey. (Photo from: Trulia) In California, when most people think about faults, their thoughts are immediately drawn to the San Andreas, and to a lesser extent, the Hayward Fault. No data point selected. Scientists are now saying that the “Big One” in California may not be caused by the San Andreas fault line, but by the Hayward Bay fault line. Click on a pin on the map to see more information. The new San Pablo Bay link between the Rodgers Creek Fault (which extends out of the image to the upper left to Santa Rosa) and the Hayward fault (which joins the Calaveras Fault out of the image to the lower right) is orange. Using the forecasts, we can properly engineer structures, plan for earthquake response, and be prepared at home to make a big difference in the impact of a significant earthquake. The Hayward fault in the San Francisco Bay area runs through a densely-populated area, so it has been studied quite a bit. Posted April 19, 2018, under Blog. It has an average repeat cycle of 140 years. Dislocation models of the surface deformation adjacent to the Hayward fault measured with the global positioning system and interferometric synthetic aperture radar favor creep at ∼7 millimeters per year to the bottom of the seismogenic zone along a ∼20-kilometer-long northern fault segment. The USGS also has a webpage that analyzes what will happen if a 7.0 earthquake has its epicenter in Oakland or Fremont. Many earthquakes have occurred along it, including famous ones in 1857, 1906 and 1989. Historic information doesn’t provide enough data to establish whether or not there is a pattern in the timing of earthquakes, but paleoseismology has provided an abundance of data. The highway paralleling the lakes to the left is Interstate 280, ``the most beautiful urban highway in the United States''. A paleoseismic study in 2007 at Tyson’s Lagoon (now a BART station) found evidence for 12 paleoearthquakes (including the historical 1868 earthquake) with an average time between earthquakes of about 160 years. The Hayward Fault is 40 miles long and about 8 miles deep and trends along the east side of San Francisco Bay. Four urban areas of the San Andreas Fault System in Northern California have accumulated a sufficient amount of energy to produce major earthquakes, a new study finds. Analysis of a geodetic network of 115 lines crossing the San Andreas, Hayward, and Calaveras faults in the vicinity of San Francisco Bay and measured repeatedly between 1970 and 1980 has revealed details about the accommodation of relative plate motion in this area. Over 155,000 housing unites will suffer enough damage to become  uninhabitable  and 350,000 people will be displaced. Where does the information come from? It runs through densely populated areas, including Richmond, El Cerrito, Berkeley, Oakland, San Leandro, Castro Valley, Hayward, Union City, Fremont, and San Jose. Along the southernmost San Andreas, from Palm Springs to the Salton Sea, earthquakes happen infrequently, about every 200-300 years. Exposure of the San Andreas Fault in a trench. The Hayward Fault. You might think that would be good because then you could leave the area beforehand and then return after the earthquake. The Hayward fault is a 90 kilometer long crack in the Earth's crust that travels through the San Francisco Bay area. However, creep occurs in spots along the Hayward Fault. Its last major rupture occurred in 1868, during California's frontier days, and was the original "Great San Francisco Earthquake" until 1906.. Introduction [2] The Hayward Fault is located on the eastern side of San Francisco Bay, California, and forms one branch of the San Andreas Fault system that accommodates the relative motion between the North American and Pacific plates. 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. Although the region was sparsely populated, the quake on the Hayward Fault was one of the most destructive in California’s history. CHART SHOWING THE HISTORY OF LARGE EARTHQUAKES ALONG THE CASCADIA EARTHQUAKE TIME LINE, MIRROR IMAGE COMPARISON BETWEEN THE CASCADIA FAULT SHOWN ON THE RIGHT AND THE SUMATRA EARTHQUAKE ON THE LEFT THAT KILLED OVER 260,000 PEOPLE. This website is intended to help clients of Bay Area Retrofit to understand their retrofit proposals. (Credit: Kate Scharer, USGS. At the time, it was known as the 'great San Francisco quake' (this was before the infamous 1906 quake, produced by the San Andreas fault), and it produced massive amounts of damage and several people lost their lives. Let's start in southern California and work our way north. The Hayward fault slips in large earthquakes and by aseismic creep observed along its surface trace. 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. Since then, nearly three million people have moved next to the Hayward fault with little regard for its earthquake potential. Click the … Comparing the data from sites like Wrightwood and Frazier Mountain, earthquake scientists are working to understand the pattern of large earthquakes – asking questions such as how typical was the large (M7.9) earthquake in 1857? Thick red lines show the extent of historic ruptures. Public domain.). The ground consistently moves a few millimeters each year, pulling apart sidewalks, pipelines and other structures that sit astride the fault. (Credit: Kate Scharer, USGS. This means that earthquakes as large as M=7.4 are possible on both sides of San Francisco Bay, rather than just on the San Andreas, as we had thought before. The Hayward Fault is an offset of the San Andreas Fault system that dominates the landforms of eastern San Francisco Bay. Or is the size of the 1812 earthquake (~M7.1) more common? The slip rate near the San Andreas fault is … Scientists are keeping a nervous eye on the Hayward fault, which runs along the most urbanized edge of San Francisco’s East Bay.The Hayward fault activity is capable of generating destructive earthquakes. The Hayward Fault. Earthquake country just got a little scarier. Thick red lines show the extent of historic ruptures. Cartoon sketch of the Pacific Plate-North American Plate boundary showing the San Andreas Fault. Note that because the magnitude scale is a log scale, there is about a 25-fold difference in the energy released by these different earthquakes. The Hayward Fault dissects Fremont creating offset features. The San Andreas Fault and the San Francisco Bay Area This image shows San Andreas Lake and Crystal Springs reservoir from the air, looking SouthEast from HERE. The Maacama fault is the northward continuation of the Hayward-Rodgers Creek fault system in northern California. The corrosion problem of ACQ treated lumber. Many of the sites paleoseismologists have been studying are along key sections of the SAFZ where there is a large population or major infrastructure that would be affected by a large earthquake in the future. The San Andreas fault zone has been a very significant source of major California earthquakes. From 1812 to 1906 it generated four major earthquakes of M 7 or larger in two pairs on two major portions of the fault. The ground consistently moves a few millimeters each year, pulling apart sidewalks, pipelines and other structures that sit astride the fault. North to south, it runs from just west of Pinole Point on the south shore of San Pablo Bay and through Berkeley (just under the western rim of the On page 10 of Seismic Behavior of Level and Stepped Cripple Walls by Y. H. Chai, it states, “More than half of the $40 billion dollar property losses in the Northridge Earthquake were due to failures of wood frame construction, primarily as a result of the damage or collapse of residential, single-family homes ……………..”  Damage from the Hayward Fault will greatly exceed this. Sorry for posting all the documentaries and I can’t really tell you which one is best. Since then, research has indicated that the likelihood of a Hayward quake is greater and more threatening to the 7 million Bay Area residents than a San Andreas … The faults are boundaries between blocks, and each block is constantly moving, which we can see by analyzing GPS (Global Positioning System) data. The Hayward fault in the San Francisco Bay area runs through a densely-populated area, so it has been studied quite a bit.The most recent major earthquake on this fault was approximately M6.9 and occurred in 1868. The In 1836 there was a large earthquake but the larges was felt on October 21, 1868. Since we have exceeded the average, many people use the term “overdue,” but it’s more complicated than that. San Francisco Bay Area Earthquakes: The Hayward and San Andreas Faults are probably the most studied earthquake faults in the world, so a lot is known about them. The Hayward fault is due for another large earthquake very soon. Scientists say the region appears to be overdue for a significant quake. Near fault shear strain rates are 0.6 ± 0.1 μstrain/yr (engineering) with direction N47°W ± 9. West of the San Andreas fault, the 400-kilometer-long San Gregorio-Hosgri fault extends primarily offshore between Point Conception and Bolinas, and sits within 3 nautical miles (in state waters) of the Diablo Canyon Power Plant. The San Andreas has long been the quake fault California fears the most. When it stops, your body moves as it is pushed forward. New studies farther to the northwest along the Peninsula section of the San Andreas Fault also show a long interval between the 1906 earthquake and the previous earthquake, which occurred around 1300. A pair of major earthquakes occurred on the central to southern region, where the 1857 faulting overlapped the 1812 earthquake faulting. Along the San Francisco peninsula no detectable slip occurs (less than 1.5 mm/yr) at the surface, but appreciable strain is accumulating. The magnitude-6.8 earthquake event used in this analysis is a slightly different scenario for a Hayward earthquake than the magnitude-6.9 event analyzed in 2007. Drop, Cover and Hold On sign. We have identified 4 common types of house and have written web pages and made videos to show you how to retrofit them. At that location, the record is about 1000 years long, and in that time period, there are about 9 large earthquakes recorded in the sediments, including the 1857 rupture. San Andreas. In 2014, a paleoseismology site at Hael Creek on the Maacama fault reiterated the results found on the Hayward fault to the south – creeping with infrequent large earthquakes, and a large one expected in the not-too-distant future. The fault has been creeping about 4.6 mm/yr (0.2 inches/yr) for the last several decades, but that is only half of the long-term slip rate, so stress is building upon this fault. The four areas singled out in the study are: Hayward, Rodgers Creek, northern Calaveras and Green Valley. Berkeley Seismological Laboratory). This fault regularly generates 9.0 temblors similar to the 2004 Sumatra earthquake and tsunami that killed over 227,000 people in Indonesia and India. This page was last edited on 23 August 2020, at 21:45. unconsolidated surficial deposits. History shows that five large earthquakes on the Hayward fault have occurred on average every 150 years—last being in 1868. DAMAGE LIKE THIS IS A VERY REAL POSSIBILITY WHEN THE CASCADIA SUBDUCTION ZONE RUPTURES, Retrofitting Bay Area Homes for 25 Years and Still Counting, The Coming Bay Area Earthquake: 2010 Update of Scenario for a Magnitude 7.0 Earthquake on the Hayward Fault. The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California. The data show that at many places along the San Andreas Fault, we have gone past the average time between large earthquakes. Public domain.). Earthquake country just got a little scarier. The city of Ukiah, in Northern California sits right next to the Maacama Fault, which is capable of M=7.5 earthquakes and poses a significant threat to the region. . The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. Investigating past earthquakes to inform the future. The average time interval between the 5 most recent earthquakes is a little shorter, about 140 years. Basically, because it’s a big fault that is close to some big cities. In fact, when the "big one" happens, it is more likely to happen on the Hayward Fault than it is to happen on the San Andreas Fault. DAMAGE LIKE THIS IS A VERY REAL POSSIBILITY WHEN THE CASCADIA SUBDUCTION ZONE RUPTURES    Courtesy the Daily Mail. And what does it mean? The resulting 3000-year record includes 29 surface-rupturing earthquakes. Homeowner’s Guide to Seismic Retrofitting. 1 B). 510-548-1111. The most recent earthquake occurred during the time of Spanish exploration, about 300 years ago, but there is no historic record of the event. The scariest scenario for the next major earthquake may […] This fault is about 74 mi (119 km) long, situated mainly along the western base of the hills on the east side of San Francisco Bay. The paleoseismic data on different parts of the San Andreas Fault Zone are all telling us that some sections appear to be past the average, or "overdue" for a significant earthquake. The most recent major earthquake on this fault was approximately M6.9 and occurred in 1868. In other words, in 11 more years we will have exceeded the historic maximum span of 160 years (U.C. Many smaller faults branch from and join the San Andreas fault zone. Near fault shear strain rates are 0.6 ± 0.1 μstrain/yr (engineering) with direction N47°W ± 9. Its last major rupture occurred in 1868, during California's frontier days, and was the original "Great San Francisco Earthquake" until 1906.. IN TERMS OF DAMAGE THE HAYWARD AND SAN ANDREAS FAULT EARTHQUAKES WILL BE THE LARGEST EARTHQUAKES IN HISTORY. The San Andreas has long been the quake fault California fears the most. Bay Area Retrofit does not recommend performing a retrofit without the guidance and supervision of experienced and knowledgeable retrofit professionals, and is not responsible for costly errors, injuries, or earthquake damage that result from such attempts. Bond #SC6334450 The relative motion between these two tectonic plates is 50 mm/yr (about 2 inches/yr), but that rate is distributed across all the faults that are part of the SAFZ. But the data can’t be used to make predictions: we do not understand earthquakes well enough to know exactly where the next earthquake will occur, what the magnitude will be, or exactly when it will happen. The Santa Cruz section stretches 62 km (39 mi) from Los Gatos (near San Jose) to San Juan Bautista, CA and was last ruptured in the famous 1906 San Francisco earthquake. First, let's zoom out and look at the big picture. San Francisco Bay and Parkfield that have preinstrumental and modern earthquake epicenters and have towns that can provide felt intensities. It is parallel to and east of its more famous (and much longer) sister fault, the San Andreas Fault. This in turn can cause the Hayward Fault to rupture. New Study Finds Hayward Fault More Dangerous Than San Andreas. The Hayward fault is a 90 kilometer long crack in the Earth's crust that travels through the San Francisco Bay area. The San Francisco Bay area is crossed by several right-lateral strike-slip faults of the San Andreas fault zone. The highway paralleling the lakes to the left is Interstate 280, ``the most beautiful urban highway in the United States''. To see the full scale of the devastation when that tsunami recedes, you would need to be in the international space station.”  FEMA conservatively anticipates a death toll of 13,000. 1. Contractor The Hayward fault runs through the East Bay hills from Richmond to San Jose. The 1906 San Francisco earthquake is estimated to have been in the 7.8 range (and possibly even larger.) The author Kathryn Schultz writes “When the next very big earthquake hits, the northwest edge of the continent, from California to Canada and the continental shelf to the Cascades, will drop by as much as six feet and rebound thirty to a hundred feet to the west . (Play Video) San Francisco Bay Area Earthquakes: The Hayward and San Andreas Faults are probably the most studied earthquake faults in the world, so a lot is known about them. Maybe you’ve heard that the “Big One is overdue” on the San Andreas Fault. The Hayward Fault is 40 miles long and about 8 miles deep and trends along the east side of San Francisco Bay. ?, respectively, and persist to the base of the crust. With about 45 years between the historic earthquakes but about 160 years since the last one, it is clear that the fault does not behave like a clock with a regular beat. Map of faults in southern California. and 70? While the San Andreas fault that triggered the great 1906 San Francisco earthquake has become ingrained in California culture, new … 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. Map of faults in northern California. The San Andreas Fault is a crack in the Earth's crust in California, some 680 miles long. The fault has been creeping about 4.6 mm/yr (0.2 inches/yr) for the last several decades, but that is only half of the long-term slip rate, so stress is building upon this fault. This shows that the average time between earthquakes includes some intervals that are short and some intervals that are long. No one can predict earthquakes, so what does the science really say? The Hayward Fault. As of 2020 it has been 151 years since the last big earthquake in 1868. The Hayward fault dataset includes 1489 earthquakes with magnitudes from … IT IS NOT INTENDED AS A GUIDE FOR DIY RETROFITS. ...and thank-you to the Facebook poster who gave us the idea for the title! CBS News did a short but excellent documentary on the huge impact a rupture of the Cascadia Fault will have on our country. Bold numbers show the average time between big earthquakes, determined at paleoseismic sites (triangles). The entire San Andreas fault system is more than 800 miles long and extends to depths of at least 10 miles within the Earth. Our Influence on Retrofit Building Codes, Shear Transfer Ties No Cripple Wall Retrofits, Brick Foundations and Earthquake Retrofitting, Workers’ Compensation and Liability Insurance. The 1906 San Francisco earthquake is estimated to have been in the 7.8 range (and possibly even larger.) San Jose, Sunnyvale, Fremont, Oakland, Berkeley and Surrounding Areas The fault has been creeping about 4.6 mm/yr (0.2 inches/yr) for the last several decades, but that is only half of the long-term slip rate, so stress is building upon this fault. The Hayward Fault splinters from the Calaveras Fault, which itself is an offshoot of the The recurrence intervals (times between earthquakes) at Wrightwood are more regular than clustered (determined by a mathematical analysis), and only four times in the past has the interval between two major earthquakes been longer than the current interval (since 1857). San Andreas. Be sure and click the Map View and watch the videos. This means that earthquakes as large as M=7.4 are possible on both sides of San Francisco Bay, rather than just on the San Andreas, as we had thought before. The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California. Copyright © 2020 Bay Area Retrofit. The Hayward Fault is a "tectonic time bomb, due any time for another magnitude 6.8 to 7.0 earthquake," according to a 2008 USGS report. The New Yorker published an article, “The Really Big One,” which warns that the Cascadia Fault is even more dangerous than the Hayward Fault. THE HAYWARD FAULT IS CONNECTED TO A SERIES OF SMALLER FAULT THAT MIGHT ERUPT AT THE SAME TIME CREATING A 7.3 OR HIGHER MAGNITUDE EARTHQUAKE. The Hayward Fault runs south through densely populated areas, including the cities of Richmond, El Cerrito, Berkeley, Oakland, San Leandro, Hayward, Union city, Fremont, and San Jose. Bay Area Retrofit assumes no responsibility or liability for use by homeowners, contractors, engineers, or anyone else of the information provided on this site. This includes Cripple Wall Retrofits, No Cripple Wall Retrofits, Retrofits of Homes with Living Area above a Garage, and Hillside Home Retrofits, THE SAN ANDREAS FAULT IS QUITE DANGEROUS AND CAN CREATE AN EARTHQUAKE 8.0 OR MORE ON THE RICHTER SCALE. CHART SHOWING THE MAGNITUDE AND DATES OF LARGE EARTHQUAKES IN CALIFORNIA. When the ground stops suddenly the house wants to keep on going and slides off the foundation. Public domain.). An earthquake occurs when the stress from the force of the moving plate overcomes the friction causing the plate boundary edges, the fault, to stick. The San Andreas fault system (SAFS) consists of over a dozen faults that accommodate motion between the North American and Pacific Plates (Fig. (Public domain.). The 150th anniversary of the 1868 earthquake, and all historical earthquake anniversaries, are opportunities to remind people that we live in earthquake country and New Study Finds Hayward Fault More Dangerous Than San Andreas. Where does the information come from? Instead, radiocarbon dating provides the age of the most recent earthquake and six more that occurred since about 800 A.D. A paleoseismology site in Wrightwood, CA has been studied by several scientists, and recently (in 2010) the detailed data from multiple studies were joined together to create a single timeline. 408-664-6355 Here is the graphic history of earthquakes on the Hayward fault. The last major earthquake that the Hayward fault produced was in 1868. The San Andreas Fault is locked in many places; much of its energy is released in the form of earthquakes. The transform boundary initiated about 30 million years ago when a spreading ridge separating the Pacific and Farallon Plates intersected with the North American continental crust near what is now Los Angeles, California (Fig. . Personally I like the following 50 minute BBC documentary on the Cascadia Fault which triggers the San Andreas Fault 75% of the time when it ruptures. The Hayward Fault is a "tectonic time bomb, due any time for another magnitude 6.8 to 7.0 earthquake," according to a 2008 USGS report. The San Andreas Fault is the most famous fault in the world. Fault-plane reflections reveal that two of these faults, the San Andreas and Hayward, dip toward each other below seismogenic depths at 60?? The chart below should give you some perspective on how much devastation this is compared to other large earthquakes. However, the edges of the blocks, the faults themselves, are stuck and only move where there is a large earthquake (some faults creep a little bit, but most are locked). Four urban areas of the San Andreas Fault System in Northern California have accumulated a sufficient amount of energy to produce major earthquakes, a new study finds. Like the Loma Prieta earthquake of 1989, the San Andreas Fault was responsible for … The North Coast section of the San Andreas Fault is north of San Francisco. Most cities in South Bay are about 5 miles from the San Andreas fault, while the Hayward faults cuts through many East Bay cities (see California Geological Survey - CGS's Information Warehouse.). This fault, called a “tectonic time bomb,” is about 74 miles long. Other articles where Hayward Fault is discussed: California: Relief: The Hayward Fault in the San Francisco Bay Area and the San Gabriel fault zone in metropolitan Los Angeles have produced several major earthquakes, though the destructive quake centred in the Los Angeles suburb of Northridge in 1994 occurred along one of the San Andreas’s larger… The San Andreas Fault is locked in many places; much of its energy is released in the form of earthquakes. And what does it mean? San Francisco Bay Area Earthquakes: The Hayward and San Andreas Faults are probably the most studied earthquake faults in the world, so a lot is known about them. Along the San Francisco peninsula no detectable slip occurs (less than 1.5 mm/yr) at the surface, but appreciable strain is accumulating. Contractors Lic #558462 The similar magnitude 2011 Tohoku 9.0 earthquake that caused the Fukushima nuclear disaster is discussed in this 3-minute video. The San Francisco Bay area is crossed by several right-lateral strike-slip faults of the San Andreas fault zone. Hayward Bay Fault Could Be More Dangerous Than San Andreas: It’s a “Ticking Time Bomb” The following video is brought to you courtesy of the DAHBOO77 YouTube Channel. The “zone” part of the name means it’s a system with the main fault and many sub-parallel faults that all together take up the motion between the two plates. Liability Ins PCA 1045011 The threat to San Francisco from the Hayward fault was recognized by A. C. Lawson in 1908 in Report of the State Earthquake Commission, The California earthquake of April 18, 1906, p. 447: "The foot of Market Street, San Francisco, is about midway between the San Andreas rift and the fault scarp upon which movement occurred in 1868. Fault-plane reflections reveal that two of these faults, the San Andreas and Hayward, dip toward each other below seismogenic depths at 60° and 70°, respectively, and persist to the base of the crust. The SAFZ is the main part of the boundary between the Pacific tectonic plate on the west side and the North American plate on the east side. The earthquake will cause $90.4 billion damage to residential buildings and 96.4 to commercial buildings. Scientists have a good big picture understanding of the San Andreas Fault Zone (SAFZ).
