Now THIS is potential for THE BIG ONE!!

Aw, C'mon. Just a little rock 'n roll in the tumultuous lives of Californians.

Now THIS is potential for THE BIG ONE!!

Could be a lead in for either the California big one or the Juan de Fuca mega thrust. This happened outside of the San Andreas on the very south end of the Juan de Fuca plate. What is more concerning is the on shore swarm east of the San Andreas and north of Sacremento from 0.3 to 2.6 some 75 of them starting around 7 am this morning PST. I have a strange feeling the two are connected some how. This is not normal.

On a serious note and yes I did chuckle at your comment, this is a watcher as something much bigger could come from this.

When there's a tsunami warning I wouldn't call that just a little rock and roll. It's not often we have a tsunami warning. But historically those kinds of EQ are not typical. Just saying

I always thought "the big one" would come after the tectonic plates had been silent for a while. In my mind I'm thinking earthquake activity will relax things some... but that's probably not how it works. I think @1LoverofGod lives in California so if the big one happens she may find herself on a floating island. Well, so much for that theory...

California Will Never Break Off From The US And Fall Into The Ocean​

It's something we've all heard before "The next big California earthquake and the entire state will fall into the ocean" or some variation thereof. Despite the geology and physics that only exist in Dwayne Johnson movies, this will not happen for a number of reasons.

Geology is a relatively new science, only really gaining momentum a few hundred years ago, with a lot to learn and tremendous advancements in the field in short time periods. As with most scientific fields, the general population aren't as well informed on the current research and data that supports our predictions and understanding. This allows for movies and fiction to perpetuate unrealistic scenarios and the general population to lack the ability to fully discern where Hollywood ends and science begins.

Imagine you watched a movie whereby aliens could take over a host human's body, grow to adolescence, and burst out of the host human all without the host knowing it was incubating an alien. The general public's understanding of biology, astrobiology, and human experience naturally steps in and raises alarms that this is clearly fictitious with no scientific or colloquial base. On the other hand, imagine a movie whereby an enormous earthquake triggers parts of California to fall into the ocean, splitting the state and triggering a massive tsunami. The general public's understanding likely leads them to believe this is overly exaggerated but that it could in fact happen in a less dramatic fashion. This is despite clear geologic and scientific evidence and understanding that this would not happen.

I would much rather float away on a California island than have myself buried beneath a pile of rubble.
I'm not afraid to die but it's those agonizing moments waiting to die that I could do without

To add

I have listened to Lucy Jones from Cal Tech and it's been a long time overdue for the Big One and there doesn't have to be a major EQ for it to happen. It could start with a low foreshock and the aftershock could be that Big One.

I think where I grew up in Ventura county is on a shelf so I think that part of California could theoretically break off.

Keeping eyes on The appearing of our Lord and hearing a Trumpet sound has a much better foresight than the breaking off of earth from an earthquake don't you think?

Yep. I don't normally give much thought to California these days. I used to like visiting the state, but I can't afford fast food there anymore...

Destructive tsunami ‘not on the table today'

Despite a scary tsunami warning, officials from the National Oceanic and Atmospheric Administration now say that a damaging tsunami will not hit the West Coast.

Fremont evacuation orders lifted

Evacuation orders issued in Fremont have been lifted after authorities canceled a tsunami warning.

As of December 5, 2024 at 12:05 pm, The Tsunami warning has been lifted. There is no need for evacuations.

Live updates: Tsunami warning canceled after strong California earthquakes

Several earthquakes rattled Northern California and triggered a tsunami warning for parts of the coast.

I just heard of the EQ and came to check on our Californians. Glad it does not seem to have been too serious. Hopefully the big one won't pop off until after we are popped out!

Nope will not happen. Ventura and Ventura County sit squrely on the eastern edge of the Pacific plate but well above water. It is pushing against the North American plate moving North Westward while the North American plate is pushing South Westward forcing a constant contact of the edges of both plate. The old LA falling off into the ocean has long since the original though been put to rest. Movements between the Pacific and North American plates are purely lateral like taking two 2X4s and rubbing their long sides together on the ground. They will move laterally but in opposite directions and neither will rise of fall. Beside the amount of damage a nicley placed 7 magnitude quake or more will do more than enough damage it will take years to recover. We don't need to be dreaming up things much worse.

Aftershocks are ongoing after a major earthquake struck off California's coast. They could get big.

As of Thursday afternoon, the USGS forecasts up to 130 aftershocks with a magnitude of 3 or higher within the next week, and a 53% chance of aftershocks larger than magnitude 5.

"It's perfectly plausible that there could be a larger aftershock or more than one larger aftershock," Tobin said.

The fault region which produced the 7.0 earthquake is a very seismically active one.
It's called the Mendocino triple junction because three different tectonic plates meet there: the Pacific, North American, and Juan de Fuca plates.

As of this morning there have been almost 200 quakes in all with a few of them actually happening on shore and several miles in from the coast. While this could be a trigger for down the coast along the San Andreas and associated faults it could also be setting up for the megathrust quake along the North American plate from northern California all the way to BC Canada. If that one happens and depending on how much along that fault actually rips we could see something along the lines of the Japan Tohoku quake and tsunami of 2011. If that happens many major cities will be in very bad shape as they are located west of the Cascade range so evacuation east over the mountains will likely be impossible especially if it comes in the winter season and over land via I5 will be shot as many bridges and over passes will likely go down. That leaves seaborne aid at the coast with air lift inland or air lift over the mountains. The logistics to support the western parts of Northern California, Oregon, Washington and British Columbia after a major mega thrust will be horrendous to deal with. Emergency management will have its hands full for many long months to a year just getting teams and supplies into the area much less helping with evacuation out of the area.

Buildings in most of California are built to very high tolerances when it comes to earthquakes. In the '71 (give or take a year) when we got the 7.0 in SoCal in my town the only damage was to some old commercial brick buildings which lost some bricks. Brick and block don't do so well in earthquakes while framed homes experience an amazing amount of sway without damage

 

[1LoverofGod]

I'm in San Bernardino and we sit on the San Andreas Fault. We have our own seismology lab in our Community College San Bernardino Valley College and they monitor seismic activity regularly because we are sitting on the San Andreas Fault.
Southern California's Cal-Tech is the main seismic activity monitoring lab and the geology scientists there expect that the Big One will register at least a 9 on the rector scale.
When that quake hits from where it's centered, it's expected for there to be a chain reaction triggering the fault to cause a rippling effect throughout the state where the fault line is and may trigger the adjoining faults along the West Coast and that's why the idea that California could break away and supposedly sink into the ocean or become an island.
I don't believe that would happen myself. But it would be catastrophic because of the multiple fault lines in the Ring of Fire that link together.
All the science behind it is a bit too complicated to fully comprehend since they usually base expected future earthquakes on history of past earthquake patterns.
I have had the thought that there Will be a catastrophic earthquake coming that may be associated with the Seventh Trumpet judgement of a Big Earthquake that will shake the earth.
I don't plan on being here for it, Praise The Lord for Salvation in Jesus!!

That is where Japan excelled pre-sky scrapers. Their wooden buildings were built with interlocking joints and no nails or screws. It allows for extreme movement of the frame work. For the fires they used paper cover doors that would flash quickly and burn out fast saving the wood framing from catching on fire and making what fires that happened to be put out quickly.

Now for the big but, no matter what man thinks he can do, God is greater and if He wants to take down a building no matter how well it is built it will come down. We have our one good example in the walls of Jericho that came down and they were not even touched, just the sound of trumpets and shouts. By the same token if God so deems to keep a building up, no matter how much shaking happens it will not come down. This is why I put little stock in the science of seismology because it leaves out the most important factor and that is the creator of the universe.

I do have a strong feeling that at some future point in time the west coast is going to get their wake up call in a major way. Just hope many do wake up when it comes because if they don't the next one will be even worse.

From what I researched, its more likely an 8.0-8.3, still, incredibly strong.

What I worry about is the Cascadia Subduction Zone which is capable of a 9.5 if the entire fault goes at once which ranges from No Cal, all the way up the coast to southern Wash state.
