Exploring The San Andreas Fault- America's Most Dangerous Fault Zone 

14:30 That water on the right. That's a sag pond, which are often found along faults.

Talc is the reason the center section of the San Andreas produces no earthquakes. The softest mineral Talc acts like a lubricant in that section.

You have explained and documented this fault very well. Thank you!

One must remember that the San Andreas isn't just one fault, but a fault system, with several smaller faults attached (for lack of a better word) to the main fault. Many of the sub-faults have created earthquakes of 7 or greater on the Richter scale. As to the main San Andreas fault...here in the southern section there is a very good way to not only see the fault, but track it as well, from Cajon Pass, through Wrightwood, and eventually into Palmdale. In the more central section of the fault, it is easily trackable on the Carrizo Plain.

The SAF can also be thought of as a transform fault connecting two rift zones.

you forgot the Wrightwood 7.5-7.8 1812...The Capistrano EQ it actually originated on The San Andreas in the mountain town of Wrightwood CA....

Really great to see the actual place that defines it all. Post where exactly it is and the trail to get there. It’s been a long time since I hiked it.

Thank you so much for very professional & informative Documentaries, We the people Appreciate your hard Work thank you Salomon !!!! Blessings

Excellent tour. I also enjoyed the the deer and squirrel. Best wishes, 👌🏾

The Terranes on either side of the San Andreas fault (SAF) are moving in the same direction and are not the North American (NA) plate; they are part of the Cordillera, an accreted region of Terranes running from Western Alaska to Patagonia. They are not rigidly entrapped by the NA continent and are free to move contrary to the motion of NA. The Franciscan Assemblage, Salinian Terrane, Great Valley and Sierra Nevada Block are all moving NW toward the Mendocino Triple Junction and beyond into SW Oregon making Western Oregon and Washington rotate 1 degree clockwise per million years. The Pt. Reyes geologic marker @9:47 @the picture on the right illustrates the unidirectional motion of all of the aforementioned California Terranes moving to the NW. The SAF is generated through motion differences in speed and rate of the adjacent Terranes, much like the varying speeds of adjacent freeway lanes all going the same direction- Trucks and grandmas in the right lane, family sedans in the middle lanes and sports cars in the left lane flashing their lights. All of this motion is generated through Terrane conveyance by the NW (Pacific) mantle flow underneath; connected with that is the East Pacific Rise in the Sea of Cortez, Baja, each offset left-side segment is moving with the California Terranes, but at different speeds and rates.

Used to be a spot in Hayward where a sidewalk had been displaced by the fault line. City fixed it a few years ago because people kept hitting it with their cars.

I’ve also noticed the dragging of the river mouths towards the north. The Gualala is a prime example

great video, thanks for sharing

A great video and lighthearted well narrated video, many thanks, from the UK

good info, keep em coming

Great video Thanks Solomon!

These are always very interesting, thanks!

Good video - very informative and well put together and a nice 'field trip' - thanks. Can geologists measure the 'pressure/strain that is building up along the fault at any given point?

there is an overhead view of an orange (what else) grove in socal that was planted in square rows on top of the fault. the offset running through the grove is quite obvious.

Good job on this young man.

Am I right in thinking that all those files that we say are stored "in the cloud" are on supercomputers located .... er ..... over the San Andreas fault?

On the southern part of the San Andreas Fault (SAF): In some other video someone said, that the current bending to the west now, is caused by the Sierrra Nevada. The fault will straighten, some day, and go to the east. So the shear zone will got through the Sierra, some day. This is really terrifying, I think…

Why was the Fort Tejon earthquake not located on the map at Fort Tejón?

I lived in Lancaster CA. and not only hang out at the fault outside Palmdale. In the 1980s and remember all the earthquakes from 73-2019. Total adrenaline rush.

Newly identified potential for water front properties!

Man, it's so pretty. I live in Brookings, Oregon, just at the northern border. I have a great gut feeling that Smith River is going to be a bourder to something catastrophic soon. Idk why yet, though. It just keeps nagging at me. Something like that event in Hawaii 😢. Or an earthquake.

Keep up the good work!

Just remember folks this fault ISN'T the most dangerous, biggest etc at all. The real fault to worry most about is called the Cascadia fault streaching from Oregon, Washington & half way up British Columbia's coast.

There are those who would point out that the New Madrid fault would create incredibly more devastation, and perhaps the Cascadia fault also.

Is there really a power line facility there ???

Nice deer footage

The San Andreas fault DOES NOT go under the city of San Francisco. It heads out into the Pacific south of town.

It's interesting how both fences have posts on the ends. How is that possible? 😂

New Madrid fault scares me more than San andreas

Nice foot deerage

You missed northridge in 1984 Southern calif

New Madrid folks or at the nexus of Haiti

Your diagram of the San Andreas fault shows Fort Tejon too far north.

We pronounce it RAYZ not Ray es.

Northridge doesn't seem to count.

Northridge? 1994?

I can tell you're not from California, or at least Northern CA by the way you pronounce some of the names. It's ok, you say them in a logical way but Pt. Reyes should sound like Pt. "rays". San Rafael is San "ruhFEL" Tejon isn't Teehone it's "tehHONE". Those lakes on the peninsula are Lake Merced and San Andreas Lake. The fault takes it's name from that lake which itself takes it's name from the valley it's in.

Why did they leave San Diego off the map?... Rockhounding with Griffin yt channel said he was trying to contact you. BTW not much will happen to sf or la when the big one comes because of the new building codes.... unless developers bribed building inspectors, in that case it's gonna be fun to watch the destruction

False. This is far from the most dangerous fault line in the US. The Alaska fault line, New Madian fault line and the Cascada Faults all rank higher.

A little silly at times ("Do, a deer, a female deer ..." but still among the better explanations I've seen on strike/slip faults. Thanks!

Solomon's so so mundane video

Please learn to look at the lens and stop looking at your face on the screen.

Having lived in the SFO South Bay area for 30 years, I know of several cool sites that you can drive to and see San Andreas (or a few other active faults) and the freaky land formations they create. However, the PDF study found in this link ( pubs.usgs.gov/of/2005/1127/of2005-1127.pdf ) covers all of them an more. Enjoy.
