Possibility Northern California Earthquake Was A Foreshock: Geologist 

Must have been so creepy and scary! Are you still in n Cali?

stay safe and strong out there, Wendi

Whoa! Those trucks aren't exactly light either! Your comment made me laugh.

I lived in Oakland, a mile or two from the Cypress Structure, there wasn't a precursor earthquake as such. What they did detect were sharp signal changes in the weeks preceding the quake. The equipment that the researches were using was turned to pick up ultra-low-frequency electromagnetic waves. No one felt those changes in the magnetic waves. But do you remember the loud pop that was just milliseconds before all hell broke loose during Loma Prieta.

@@SuzyEH I was in my 4th floor office on Castro Street, downtown Mountain View, about 3.5 miles from the primary epicenter. I say primary because there was a secondary rupture of a previously unknown South-North fault west of the Hayward fault, out in the Bay under the mud, which was what spread the Bay Bridge enough to let that roadbed panel pull off the pylons and drop. I hadn't heard about a pop until now, and don't know if that huge collapse might have been what you heard. Or not. In any even, I'm sure the entire bridge rang like a bell. My experience seemed like an intense psychic vibration that rattled my ears, teeth and joints as the atmospheric aspect of the P-wave flashed through just before things began to move. I had just enough time to call out "Earthquake" and as you say, "all hell broke loose" as I was telling my confused colleagues to take cover. One had felt it also bout didn't know what it was, and the other was astonished that I knew an earthquake (shaking) was coming before it arrived. Which explains why the first understood me instantly and was already dropping to get under the desk while the second was still sitting there trying to make sense of what I had said. Loma Prieta was not my first big Quake. That was the 1959 7.3 Hegben Lake (Yellowstone) earthquake with its half-dozen 5.9 yo 6.3 aftershocks over the next day or two, as enjoyed in Manhattan Montana about 65 miles north of epicenter. My brothers and I sat on the lawn and watched the waves roll at us along the sidewalk, tipping the concrete squares up and down, and whipping the trees back and forth. We all four felt them coming in the same way I described above, except that Brother #2's experience was intense and painful. He's one of those guys who can't walk through a retail security detector without a blast of pain through his head. Back to today and the point at hand. Wikipedia mentions two Loma Prieta foreshocks in the low to mid 5s in the 1988-89 months preceding the actual quake. In 1988 I experienced another 5.1, that I recall as the first before those two, at a red light on Calaveras Blvd. in Milpitas. It centered on the Calaveras fault very close to yesterday's 5.1 and 3.1 epicenters. It may not have been considered a Loma Prieta foreshock because it was not on the same (San Andreas) fault,which is why I called it a precursor. Over the pat few years it has become apparent that earthquake stresses "travel" akin to systemic ULF waves along and across plate boundaries and among interconnected faults. A release (EQ) in one place transfers stress downline and is followed by a later quake there. Amateur pattern-mapping projects and rudimentary prediction models are being developed and reported on RU-vid. I'm going to be very keen on watching the next 6-18 months unfold, to see if a similar progression occurs.

and how many 4-5 magnitude earthquakes have occurred since 1989 with NO larger one following? ppl like to be all dramatic LOL

@@AD-sp5cv In the same spot? Or did you not read enough to make an intrlligent comment?

I would wait until we get 1 or 2 more mag 4.5 or greater quakes in that area before making that assumption!

Don't you have a sea of Mexicans already

@@jamescoleakaericunderwood2503 lol its just a inside joke among arizonans.. Obviously its been disproven that cali can fall into the ocean.

more like they already got stupid lol

I live in Seattle. I talked to a guy with FEMA after the Cascadia Rising (I think that was the name) drill that bought all the agencies together for a drill. Having lived in Oakland for Loma Prieta, had to be the most terrifying moments of my life, I know how bad it's going to be. The FEMA guy told me it's pretty bleak if a 8 or better hits, airport gone, ports gone, all bridges gone. It's going to be hard getting aid to the area quickly. He said a lot of people might have to be on their own for 2 to 3 weeks before aid arrives. My stomach has it's own quake when I think about the event and it scares me for the Bay Area having lived there. Will the big one bring Millennium Tower to the ground?

@@SuzyEH That fault could trigger a tsunami too.

This guy always nails it hands down ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4NB5oTxT3qQ.html

@@SuzyEH If we all learned one thing from the Seattle "CHAZ" and the "Summer of love" back in 2019, Seattle is WELL prepared to survive doomsday. Premium gardens, trained security, people identifying as military equipment... It's gonna be something to behold.

You a Dutch fan?

Dutch exposing the truth

With wildfires & earthquakes, California is aka "Shake & Bake"

I Sadly agree California needs a good Shaking especially in San Francisco. NANCY'S destroyed this Beautiful place

Time to deal with the homeless problem, one big earthquake & tsunami will do the job.

@@christinarobleto1786 then there’ll be more homeless ppl lol.

@@elanefike5407 that nancy must be pretty powerful to have been able to destroy a city

Naw..that was my next door neighbor...she ate taco bell for lunch

It is a fact that the West Coast is loooong overdo for a Big one!

@L. plzsavethebeez I guarantee you within the next 3 years(from now to 2025), that big one will sink the whole state of california. Not part of cali, bit the whole state....... Plus that big one not only california will be affected, the whole world will feel it. It is a judgement from God.

Pretty much anywhere in the world. 😂

Soon.Loma Prieta all over again.

Yeah, it just seems like s bigger deal when you're one of them.

That makes sense.

🎯

well the san andreas can have an 8.1 so pretty much as big as alaskas quakes

It's not going to hit 10, 9 yes, 10 no.

So does a category 4 Hurricane....

Maybe you should look into it.

@@valleygirl2530 I'm retired. Looking out for the young.

@@SuzyEH san andreas cant have a 9.0 just a 8.1 the scientist said hehe

Hello John, how are you doing today!

@@amandadan3029 Hi. Thanks, for asking. I'll be fine, as will you, once I get our secondary manual backup system operational, through a matrix NGO, so to not be a potential "hostage population"... by mechanizing and empowering direct democracy, within a republic, by restoring true active and passive civil defense, where "We..." can "muster" again, to resolve crucial issues. With help, we can get this operational, by Christmas. For hints, watch... "Meet John Doe" (Gary Cooper, Barbara Stanwick) And, PBS: "Half the Sky"... In Part II, about FET.

@@amandadan3029 Oh, too... I love, folks who live the art of kindness. Very cool. Thanks, again, for asking. And, Merry Season to you. And, young lady, I'm convinced we can get this system operational, if those who know how, can just get the word out... for me. ( I'm tooooo tech ignorant, and tired... Too many long years, on really bad roads... But, I found goodies, along the way. I'm just not good at telling... ... How average folks can restore the piece they need... Basically, easy. It needs you younger folks to take it on, and make it work... So, even kids can give voice and vote. Through our own CCMC behind a Desktop Icon... (Kinda like NASA capabilities, for restoring the "mustering", (from a device), for good neighborhood incident management capabilities, too. Our matrix NGO nonprofit will kinda be like ARC's / Red Cross; but, made for the rest of us; so, we can actually become a working asset for the ARC, during desperate situations, since they become the Primary", for managing humanitarian efforts, during such... But, it's our system, our choices... A buffer... To serve us, as a neutral / objective level playing field. Anyway, I hope you get the overall picture. If you like it, pass it around. And, you're welcome to all my research about it. Textbook stuff. Mostly all quotes. (For what it's worth, long ago, EMI used my stuff, as a template, for starting their Grad Degree program, for professional training in those fields. (The guy who took it, realized, too late, he needed those copies from me, of mine, before he slammed the door, stating, he was writing his own book... And, he didn't need my stuff.". After, stating otherwise, at our last 30min call, when he speed-type all I was telling, about my stuff, and how it fit the EMI/ FEMA "Higher Education Project" goal, mission, and objective. Thusly, a waste of perfectly good OCD, in my case, and for my matching goal, mission, objective s. Thusly, old, broke, broken... ... Hoping...??? ... Still trying...!!!...??? I'm even too tired to edit these things, any more. Oh, too. Some Jesus guy wouldn't let me turn my back on this "civil defense issue", and how it's the key to empowering democracy. Thanks, for hearing me out.

It could be weeks. It does just happen the next day.

So you were present during Loma Prieta, that was 7.1 and the most terrifying moment of my life. So just how large a quake have you been through? You would have peed down you leg during Loma Prieta.

@@SuzyEH Exactly, the October 1989 Loma Prieta earthquake was extremely terrifying. Many CA transplants who never experienced an earthquake moved out quickly following that extreme seismological activity. Another major quake is overdue for both Northern and Southern California

She says 5% of it being a foreshock heh. its interesting watching different scientists. i trust her the most tho hah

Apparently you don’t read the Bible. Read Luke 21 verse 11.

How about pumping all the ground water san jouquin valley... '

@@wadewilliams9702 I don't read fairly tales, so no.

@@johnwunder3521 The San Joaquin Valley is much further south. The problem there is subsidence, the ground is sinking. The quake today was on a part of the Hayward fault, that has been there for 1000 of years.

Omg 😂

A 5.1 quake is a moderate quake that can rattle your body/nerves but usually won't cause property damage or injuries

Not to mention its the biggest quake bay area has seen since 2014 lol. Cali doesnt have earthquakes like all the hype says

???????

It has been ever since the planet was formed. Just like we are all dying and have been since we were conceived so not really that scary.

Quakes can kill people of all persuasions/types/genders/ages. Quakes don't pick and choose who dies or how, same as all natural disasters/extreme weather
