Disaster in California: I went to the San Andreas Fault

California is expecting a mega earthquake soon.
I went to the actual San Andreas fault to see what might be ground zero for California's biggest problem. There I saw the effects of the shifting tectonic plates.
The San Andreas Fault is probably one of the most famous fault lines in the world. The fault line separates the North American plate from the Pacific plate. It runs down the length of California, goes right through San Francisco, and right by Los Angeles.
This fault has a right-lateral strike-slip motion. This means that the two plates are effectively moving horizontally past each other.
The Pacific plate is sliding north while the North American plate is sliding south. This slippage is extremely slow. The plates only move about 1.3-1.5 in (33-37mm) a year.
However, that's just the average rate of motion. These slippages don’t happen every year. The pressure builds up more and more over the years and then slips in one large earthquake. This is what is most concerning about fault lines like this one.
The last earthquake on the fault line was in 2004 in Parkfield CA. This was only a 6.0 magnitude earthquake and Parkfield actually gets consistent earthquakes every few decades. Due to their high frequency, the earthquakes here are typically not that severe.
Before that, was the infamous 1906 earthquake in San Francisco which was 7.8 in magnitude.
Before that was the 1857 Fort Tejon earthquake, which despite its name was located once again in Parkfield CA. This was a 7.9 magnitude earthquake. There were only 2 deaths reported, but this was 1857 and the population of California was less than half a million.
In 2015, the Uniform California Earthquake Rupture Forecast published its prediction of when the “big one” would hit. It predicted that in the next 30 years Southern California has a 100% chance of seeing a 6.0 magnitude earthquake or greater. Furthermore there is a 75% chance of a 7.0 earthquake, and 7% chance of a 8.0 earthquake.
Unlike hurricanes, tornados, or wildfires, there is really no warning when an earthquake will hit. California has been retrofitting buildings to withstand earthquakes, but not all buildings have been retrofitted. Also, even if buildings withstand the earthquake, there still is the concern that the roads will be smashed and that power and water distribution will be cut off for an extended period of time. Remember the 1906 earthquake in San Francisco? Most of the damage didn’t come from the actual earthquake, but from the fires that erupted after the gas mains ruptured. If the big one hits us, there will likely be a period of time when people are unable to leave the area, and unable to get critical resources like food, water, and medical care.
Make sure you have plenty of water stored at home. You should store about 1 gallon per person per day. Also keep a large amount of food that doesn’t need to be refrigerated or cooked. I have a bucket of freeze dried food that has a shelf life of 25 years. You should also have flashlights, a fire extinguisher or fire blankets, a medical kit, a radio (since cell phones and internet will probably be down) and even liquid waste deodorizing power which you put into your bucket toilet. Yeah that’s a real thing.

@eddog6666 Год назад

Unfortunately the next major quake may not be San Andreas one. The one that is most likely to rupture is the ridyer ridge creek fault. Which runs smack through vellejo California and perhaps crosses the water which is the Hayward fault.

@blackholeentry3489 Год назад

I read about a young man, who as a teenager lived in Los Angelos during the quake there in the 80's? (not sure of the year) He vowed just as soon as he was able, he was moving away from the area...and he did. He relocated in the state of Washington, near MT St Helens and he wasn't there very long before the mountain erupted. I'm not sure if he stayed there or moved on yet again.

@bluesnote1 Год назад

Hi there! Geophysicist here! Really cool video, especially liked the drone shots. A few key points I'd like to address for accuracy: While most people assume faults are lines, they are actually consisted of many fault lines (mm to m scale) within a given fault zone of some width (usually a few tens of meters wide, but can be a few 100s as well), especially at the surface. As you go in depth they likely converge into a singe fault plane or few main fault planes. The valley at the top of the Tejon Pass, the one in the video, is the entire fault zone. There are smaller strands of the San Andreas on the north side of the bridge that crosses I-5, while the cool rock feature you pointed out was on the south side. Also, Tejon is pronounced Te-ho-an (same with Cajon as Ca-ho-an). The Pacific Plate is an oceanic plate, not a continent unlike the North American Plate. You forgot to include the 1989 Loma Prieta Earthquake which was on the San Andreas Fault near Santa Cruz, although some argue it originated on a splay of the San Andreas and not exactly on the San Andreas. Interesting that the 2015 study was correct about a 6 or higher earthquake occurring in Southern California as in 2019, the Ridgecrest Earthquake sequence had a 6.4 and a 7.1. The Parkfield earthquakes occur regularly and around the same magnitude due to the different lithology (geology of the strata) at depth. In the central region of the San Andreas Fault the rocks transition from granite in the south to sedimentary and metamorphic features towards the north. This is due to the region having a subduction zone offshore which occurred prior to the existence of the San Andras Fault. It is believed that serpentinite created from subduction can be found at depth below the San Andreas and the area around it. Hydrothermal interaction with this mineral can chemically change it into talc, one of the softest minerals which essentially lubricates the fault plane and allows the San Andreas in this region to be constantly moving (or creep). Between Parkfield and Carizzo plane, the fault transitions from fully locked to fully creep and somewhere in between the fault kinda does both. This is why we can get similarly sized earthquakes on semi-regular intervals. Some say that the Fort Tejon earthquake was a Parkfield earthquake that just slipped a bit too much into the fully locked section. But who knows lol. Hope this gives some more context on the San Andreas :)

@DataTime27 Год назад

Thanks bluesnote1. Yes I should have included the Loma Prieta Earthquake, especially since I lived through it :-D.

@blackholeentry3489 Год назад

Thanks for the informative reply. I live in Watsonville, which is near the epicenter of the Loma Prieta earthquake...and I happened to be at work when it hit. I worked at Moss Landing, at the Kaiser plant, right next to the PG&E power plant, which has 500' tall stacks. I had heard those stacks move during an earthquake, so went charging down a flight of stairs to get out into the open to see it....sure enough, they were moving and I watched them slowly return to plumb. About then, the manager from the plant next door came running over, his face still white, and exclaimed, "Those stacks were moving 50' at the top" Had they been aligned a little differently, they would have smacked each other. I met my wife 15 years ago, while on a solo motorcycle trip, and all of this time we have lived 210 miles apart (but this is soon changing). The San Andreas fault line is a few miles east of me and I live on the Pacific Plate, while my wife lives on the American Plate. In the '89 quake, we moved about 6' closer. I've long joked with her....if we wait long enough, all we'll have to do is 'hop' across the faultline. A few miles from where I live is a granite quary which is located right on the faultline, and the other half is said to be somewhere 110 miles north, about 10 miles or so north of San Francisco, but of course, it is under water. Also, at Parkfield, there is a quaint restaurant, which I have been stopping by about once a year for lunch/dinner for over 40 years. Which reminds me, it's been a while. There is a sign/placard on the wall which reads... If you're here and the earth begins to shake.. Head outside, but don't forget your steak! After the dust had settled, geologists said we had gained 6' in elevation and had moved 6' farther north. When I told my buddy that, he remarked, "Good! I didn't like where I used to live anyway!

Has there been any research into intentionally lubricating plates in many areas simultaneously with with oil drilling or fracking technology? Computational modeling this would be groundbreaking (pun!). This could allow constant slip instead of harsh earthquakes.

@kevinday107 Год назад

Also important to note that after the Northridge Earthquake in 1994; the majority of the high rises in downtown Los Angeles alone had major cracks in the reinforced steel including the newer supposed "quake safe" structures. It has been estimated that somewhere between 40% and 60% of high rises could now collapse directly due to this weakening that happened during the Northridge Quake. Funny thing how we've known about this for over 28 years now(since Northridge); yet the proper retrofitting to fix this problem has not occurred.

@TheSpatulaCity 11 месяцев назад

As a native Southern Californian, I've lived through several bigger earthquakes. It's true that if you are in a quiet room, you can often hear the low pitch of it coming just before you feel it. Also, you can tell how close/far away it is from the type of shaking. If, your earthquake feels more like a rolling side to side motion, it originated farther away and was probably significant. If it is more violent, with up and down motion and very jerky, it originated nearby. I also heard that there's earthquake weather, which is when extreme temperatures change throughout the week.

@@melvinthomas9292 You might be thinking of US Highway 101 (the western-most of the US highways) which does run roughly, on-and-off, run up the coast of California, Oregon, and Washington. It starts just a little south-east of DTLA and ends in Olympia, WA after having made a big loop around the coast of the Olympic Peninsula. It is one of America's truly epic highways. I-5 runs (roughly) along the coast from the Mexican border, through San Diego, past Capistrano Beach then turns inland a bit into through Anaheim (Disney Land!), and then L.A., Burbank, San Fernando, over the "Grapevine" (Tejón Pass), up the middle of California in the Central Valley through Sacramento before it begins its slow climb up into Redding then Lake Shasta, Mt. Shasta, Yreka then the Oregon border. It continues north through to Portland OR., Seattle, WA, Bellingham WA, until its end at the Canadian Border. I-15 starts from I-8 just north of San Diego, heads inland up into the San Fernando Valley (near Rancho Cucamonga), over the Cajón Pass into the Mojave Desert, continues NE to Las Vegas NV, then north to Salt Lake City and eventually ends at the Canadian Border in Montana.

When other students started making fun of me, the teacher said I was the only one who did the right thing. That shut them up. There wasn’t any major damage, but it was scary.

A trip to the Salton sea is also a pretty neat place to be along side the San Andreas fault line.

I'm not a 'prepper' - but some things are just good common sense.

(Europe and Asia are sometimes considered a single continent, Eurasia.)

@user-uy6uc5ey5q Год назад

The video didn't include the term 'continent' as far as I heard but used the term 'plate' which if entirely consistent with the theory of plate tectonics. 'Continent' is a ill defined term in geology and as you seem to be aware there are various definitions which some of your list make at times and at others not. In fact there some claims there're only 3 with Antarctica, Europe + Asia and Africa as one super large connected one, and the Americas as the last. Australia is considered to be too small to be included.

In 1992 there was a 7.3 magnitude earthquake in Lander California, and was called the most substantial earthquake sequence to occur in California in the last 40 years. There have been many more significant earthquakes in California after the "infamous 1906 quake in San Fran. Some examples are,: there was the 1952 earthquake, a 7.3-magnitude quake that hit Kern County, was the third largest earthquake in recorded California history. In 1971, a 6.6 earthquake hit Sylmar. Its epicenter was the Magic Mountain amusement park, rattling outward 300 miles along the southern California coast. It killed 65 and injured 2,000. In 1989, a 6.9 earthquake hit Loma Prieta, Calif. It felled Bay Area freeway interchanges, interrupted a World Series and caused $10 billion in damage. The most recent earthquake was in 2019, when a 7.1-magnitude quake hit near Ridgecrest, Calif. Thirty million people from Sacramento to Baja Mexico felt its 24 shocks and aftershocks over three terrifying days.

@@blackholeentry3489 I don't think it's particularly expensive, especially if you regard it as catastrophic coverage. You can adjust the deductible to suit the desired annual cost. Mine is $50K, but I only pay $300/yr. I regard that as a pretty good deal.

Hi from New Zealand. You probably have the most famous fault line in the world. New Zealand has one of the most notorious fault lines outside of the United States called the Alpine Fault. Like the San Andreas It marks the boundary of two tectonic plates. Like the San Andreas, it hasn't moved for about 300 years. Like the San Andreas it is considered to be due for its next event. It is also a dextral strike slipping fault with the west side of the fault (Indo-Australian plate) moving northeast, and the east side (Pacific plate moving southwest. This might be where the similarities end. The Alpine Fault is a notoriously consistent fault that has slipped 26 times in the last 8,000 years and all have been around magnitude 8.0. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WWLZCwi_yuw.html

@user-uy6uc5ey5q Год назад

I'm from NZ as well and also lived in the Bay Area and you've given some great info apart from your claim about no movement on the San Andreas for 300 yrs. There's have been significant quakes on the fault during the last 300 yrs including as recently as 28th Sept 2004 (mag 6.0) on the Parkfield section (central California) and there been 4 other major ones before that in 1857, 1906, 1957 and 1989 in the central and northern sections. I think you mistakenly picked up that the very southern US section of the fault which runs from San Bernardino through the Coachella Valley to the Salton Sea hasn't had major movement since 1690.

@blackholeentry3489 Год назад

@@user-uy6uc5ey5q I do concede...you're right. There have been many earthquakes along the fault. However, at Parkfield, much equipment has been set up there to monitor earthquakes on both the American Plate and the Pacific Plate....where the sharp boundary of the plates can easily and visually be seen. There is a small cafe there "The Parkfield Inn" which I've been eating at for close to 50 years now...which reminds me....been a while since I've done that...and was once a favorite motorcycle destination of mine. The restaurant has had a long term policy.....if one is eating there and an earthquake hits "The meal is On the house"....or, quite possibly, on the floor!" In 1986, I toured both islands of NZ and visited your wonderful Milford Sound. I chose 1986, for as a lifetime amatuer astronomer, that was the year Halley's Comet returned, and which wasn't very visible from the northern hemisphere. Wasn't much better from the southern hemisphere either, and won't be any better in the next apparition, but because it returns only every 76 years, one takes whatever one can get. On another subject....I've a great friend from Aukland, who recently visited me again. He is a former English teacher, has had a long term fascination with John Stienbeck, which we have a museum here (On John Street in Salnas, CA....of course) He wanted to visit the museum, so spent a couple of nights at my place. For 35 years, I worked at a place at Moss Landing, CA, and was at work when the last major earthquake hit in 1989. This place is located right next to a major PG&E power generating plant with 500' tall cement stacks. I witnessed those stacks moving 50' at the top and had they been aligned slightly differently, would have smacked each other. A more modern generating plant has now been built, those 500' stacks were supposed to have been taken down in 2000, but here in 2023, remain standing. Wouldn't have wanted to be within a mile had those two stacks had actually collided. On another topic...1st met my wife while on a motorcycle trip and we have now been married for 12 years. All of this time, we have maintained two separate houses 210 miles apart, with San Francisco about midway between us, but that is about to change. Have been doing some major changes to this house in preparation to selling it. Every time I cross the Golden Gate bridge, I cannot help but think about my father, as he helped build it in the 30's. On that 1989 quake, siesmologists later concluded this area had moved 19' farther north and also gained 6' elevation. When I passed on this info to a favorite friend, he remarked, "Good! I didn't like where I used to live anyway!" BHE

There is geological evidence that the Northern SAFZ and the Cascadia Subduction Zone have triggered one another in the past. The last major Cascadia quake was in 1700. Imagine the SAFZ letting go, with the rupture heading up to the CA/OR state line, heading west off shore, then triggering a Cascadia event that continues from the CA state line all the way up to the North end of Vancouver Island in BC Canada. We know about the estimated 8.7 - 9+ magnitude1700 event due to the Japanese recording the "orphan tsunami" which suddenly hit the Japanese coast without an accompanying felt earthquake event. Yep, the tsunami from that EQ still did damage in Japan after traveling all the way across the Pacific Ocean. That one involved about 620 miles of Cascadia fault rupture with an average slippage of 66 feet. 323 years since the last release. Historically, we are about due for another one... en.wikipedia.org/wiki/1700_Cascadia_earthquake

The epicenter of the Fort Tejon (pronounced "teh hone") earthquake of 1857 is not known. Foreshocks may have been centered near Parkfield but the area that experienced the worst shaking during the main quake was Fort Tejon located near the "big bend" portion of the SA fault. The quake ruptured the ground surface for more than 200 miles between Parkfield and Wrightwood and the surface along the fault was offset by as much as 30 ft. The low number of deaths reported is due to the low population in central/southern California in 1857. However the quake is estimated to have been 8.0, stronger than the SF 1906 quake. The Carizzo Plain is a great place to view the fault trace. I'm from Bakersfield and have visited the Wallace Creek offset many times.

@candidone8544 11 месяцев назад

It's not really a secret, but the strongest California earthquakes of the past 52 years, were not on the San Andreas Fault Zone (SAFZ). Neither the 6.6 1971 San Fernando EQ nor the 6.7 1994 Northridge EQ were on the SAFZ; both were on blind faults, not previously mapped, amid the mesh of tectonic fracturing related to the mountain-building of the western Transverse Ranges. Also, neither the 7.1 2019 Ridgecrest EQ, nor the 7.1 1999 Hector Mine EQ, nor the 7.3 1992 Landers EQ were associated with the SAFZ. The latter quakes pertain to an accruing trend of quake epicenters which align with the Walker Lane Deformation Belt and the Long Valley Caldera, along the eastern flank of the Sierra Nevada, with implications of eventual transfer of SAFZ transform fault role, inland to link the East Pacific Ridge to the western flank of the Basin and Range Extension Zone.

@user-uy6uc5ey5q Год назад

Earthquakes are very complex physical phenomenon and no 2 quakes even on the same fault produce the same outcomes. Buildings can be designed to cope with various degrees of shaking, but you can't design a human structure to cope the movements that occur at fault lines when signifiant horizontal or vertical displacements happen. Classic recent example was in rural North Canterbury in NZ during the 2016 Kaikōura earthquake. A house built to NZ quake standards was ripped in two as it sat over a fault line which had displacement of 3 or more metres, where as other buildings surrounding it, but not on the fault line has some damage but were largely intact despite having basically the same degree of shaking. I'm afraid the basics of physics and building disprove you claim. You don't want to build a structure on a fault.

@candidone8544 11 месяцев назад

Gentlemen, the 7.9 1906 San Francisco Earthquake was the state's deadliest ever or since, but not directly from the shaking. In 1906, SF was mostly wood construction, which is considered as the most resilient in strong quakes. However, in 1906, SF was still in the gaslight era! Yep, uh-oh. The quake itself widely damaged the city's natural gas infrastructure and the city of wood was ready-made fuel for the ensuing fires. While most estimates claim >3,000 deaths from those post-quake fires, nobody included how crowded Chinatown fared, although it too was turned to ashes. BTW, the San Andreas Fault Zone (SAFZ) does not trace through SF; it passes offshore at Pacifica, south of SF. North of SF, most of SAFZ runs offshore or along sparsely populated coastal NorCal, with its northern terminus in the offshore Mendocino Triple Junction.

@bigc8300 Год назад

@PariahSojourner 2 месяца назад

Want some real fun? Look up the Walker Lane Fault Zone that runs through the western Mojave Desert and east of the Sierra Nevadas. Eventually, as the Eastern Pacific Plate continues to be subducted under North America and divergent strike-slip boundary that is the San Andreas moves eastward, most of the energy that creates the San Andreas Fault will transfer to Walker Lane, which is is the process of already happening. This will eventually, very slowly, pull apart the western portion of North America, creating an archipelago of islands that will migrate northwestward.
