Multiple Offshore Earthquakes Shake North Coast Before Dawn, Triggering ShakeAlerts

Some North Coast residents were awakened before dawn Wednesday by a series of offshore earthquakes that prompted ShakeAlert notifications and were felt across portions of Northern California and Southern Oregon.

According to the U.S. Geological Survey, a magnitude 5.7 earthquake struck at approximately 3:53 a.m. PDT about 104 miles west-northwest of Crescent City near the California-Oregon border. The quake occurred within the Gorda Plate offshore of the North Coast.

A second significant earthquake, a magnitude 5.2, occurred at approximately 5:53 a.m. about 40 miles west of Petrolia on the Mendocino Fault. That event was followed roughly 26 minutes later by a magnitude 4.5 earthquake in the same area.

The cluster of quakes appeared prominently on the USGS earthquake map Wednesday morning, with the two strongest North Coast events among the largest earthquakes reported worldwide over the previous several hours.

According to a post by the Redwood Coast Tsunami Work Group, some residents along the Del Norte and Curry County coasts received ShakeAlert notifications following the magnitude 5.7 event. The organization reported the earthquake was felt by a small number of people from Scotia north to Reedsport, Oregon.

The group said ShakeAlerts were also issued following the magnitude 5.2 earthquake west of Petrolia. That quake was reportedly felt lightly from Westport to Brookings, Oregon, and the subsequent magnitude 4.5 aftershock was also felt by some Humboldt County residents.

The Redwood Coast Tsunami Work Group noted that the two larger earthquakes were not directly related despite occurring within a few hours of each other.

“The first was in the Gorda plate near an area where a number of earthquake in the M5 range have occurred in the past year and the second was on the Mendocino fault and arguably an aftershock of the December 5, 2024 M7,” the organization wrote.

No tsunami warnings were issued following either earthquake, and there were no immediate reports of damage or injuries.

Oh, California, you dramatic diva.
Those offshore earthquakes this morning—5.7, 5.2, and a cheeky 4.5 aftershock rattling the North Coast before dawn—weren’t just tectonic tantrums. No, no. This was the Earth’s very own ShakeAlert to Sacramento: “Hey, the plates are shifting… and so is the electorate.”

It’s like the ground itself woke up, yawned, and said, “I’ve had it with this radical leftist experiment too.” Years of progressive utopia—sky-high taxes, rolling blackouts, streets that look like open-air encampments, and policies that turned the Golden State into the “Come for the Weather, Stay for the Regret” State—and Mother Nature finally files a formal complaint. Those quakes weren’t random; they were the planet’s way of saying, “Time for a tectonic political realignment.”

Humboldt and Del Norte residents jolted out of bed? That’s just the foreshadowing. The real rumble is coming from fed-up Californians eyeing the exit ramps (or the ballot box) after watching radical ideology turn paradise into a cautionary tale. High-speed rail to nowhere? Check. Energy policies that make rolling blackouts a lifestyle brand? Check. Crime and homelessness policies that prioritize vibes over results? The Earth just shrugged extra hard in solidarity.

Even the USGS map looked like it was drawing a giant middle finger aimed at one-party dominance. No tsunami warning, but plenty of warning signs for the political class: the ground is literally moving under their feet.

So here’s to the change that’s coming—whether it’s voters demanding sanity or the San Andreas deciding enough is enough. Either way, California’s about to get the big one… in the election results! Stay woke, folks. Or better yet, stay awake when the next alert hits.

I thought you people hated being woke, also feel free to move out of the state.

If we had it the conservative way, that earthquake would have knocked down your house, because you hate regulations. When your house is on fire, reject the help from firefighters, because you hate socialism.

Maybe if we stopped sending money to those wonderful red states everyone wants to live in, we could spend it fixing the issues here.

You know what would help not have homelessness, if the red states stopped sending their criminals and mentality ill people here. It’s cheaper to buy them a one way bus ticket than to hospitalize and help them.

Funny how you lecture us about ‘hate being woke’ while defending the very policies turning California into a magnet for exactly the chaos you ignore. Thought you people loved evidence-based governance?
Everyone sees it: addicts, zombies nodding out in the streets, open-air drug markets, perverts, and traffickers flock here because of cheap fentanyl, Prop 47-style catch-and-release for theft and drugs, zero consequences for public encampments, and de facto decriminalization of prostitution and human trafficking in too many spots.

In the 1960s, it was flower children chasing LSD and ‘free love.’ Today it’s zombies, hardcore addicts, sexual predators, and traffickers acting out their pathologies in broad daylight on our sidewalks, in parks, and near schools. Clean up the mess—enforce basic laws, clear encampments, mandate treatment, and stop the revolving door—and many would stay where they came from instead of treating California as a sanctuary for dysfunction.

Your earthquake and firefighter analogies are strawmen.

Conservatives don’t ‘hate regulations’—we want smart ones that actually work, not the bloated bureaucracy and NIMBY housing restrictions that make California unaffordable and drive up homelessness. No one rejects firefighters; we reject trillion-dollar government spending with worsening outcomes. California has poured billions into homelessness with record numbers of unsheltered people anyway—far outpacing most red states in raw failure.

And the ‘stop sending money to red states’ line? California is a net donor to the federal government—paying far more in taxes than it receives—largely because of its high earners and productive economy. But that doesn’t excuse state-level mismanagement. Red states often deliver better results on cost of living, crime, and homelessness with less spending because they prioritize enforcement, treatment, and accountability over enabling chaos.

Finally, the claim that red states ‘send their criminals and mentally ill’ here via bus tickets is overstated. Studies show the vast majority of California’s homeless became homeless in California—locals hit by high costs, addiction, and policy failures, not imports.

Yes, some relocation programs exist across the country (including in blue cities), but California’s pull is its weather, lax enforcement, and generous benefits—not a grand red-state conspiracy. If anything, people (including businesses) keep leaving California for red states seeking sanity, lower taxes, and functioning streets, am escape from woke rainbow perversions!

Move out? Many productive Californians already are. The rest of us want to fix it: enforce laws, build housing faster by cutting red tape, prioritize treatment over open use, and stop pretending compassion means tolerating squalor, needles, and public defecation. Results over slogans. Red states aren’t perfect, but California’s experiment in maximum ‘progress’ has delivered visible decline. Time to learn from what works.

You also forgot to mention that the federal government military bases here in california are a large driver of the economy , if California were not part of the united states those bases research centers and the like all funded by the federal government would not be in california reducing not only the money inserted but those direct job plus the supporting jobs housing shopping entertainment it is substantial amount of money . And for those claiming that california ‘s economy is so great then why do they spend more per student then most other states but only rank 24 th in the nation for high school test results ? I would think with such spending there should be better results perhaps if the schools were focused upon teaching things like math reading and stem subjects instead of how they can be victims and how it is not their fault that they cant learn but the evil toxic American culture that is to blame then maybe they would test higher and not have people in other states laugh and crack jokes about how their diplomas are worthless

Exactly. Welcome to the inclusive paradise where independent thought dies and the brainwashed cult thinks exactly alike. They haven’t ignored reality—they’ve just automated their brains to download the weekly activist update. Nothing screams “free thinker” quite like chanting pre-approved slogans in perfect unison while strictly obeying a hive-mind checklist.

I heard conservative view points are hardly tolerated on this blog, but so far Kym has been fair with me. It’s the radical activists on here who want to remain in an echo chamber of people they agree whole heartedly with and cannot take expressions of diversity and diverse opinions shared! A darn shame!

that’s cause nobody reads your regurgitated Fox News paragraphs. Hurry now, the South is calling. Surely none of the problems California has are present there.

I hate to tell you this but most people do not rely on regulations to determine the quality of their home . In fact most homes in this state today do not meet current regulatory mandates yet prices are through the roof . Speaking of roofs whats more important having a roof over your head or having mandated solar panels installed on a roof you cant afford due to regulations that have nothing to do with safety or living conditions ?

Cringe AI comment. Another conservative without the ability to express an original opinion. Of course this expert on California thinks earthquakes are a new phenomenon

See how the tone changes when you write your own comments instead of copying and pasting them from somewhere else: all arguments abandoned, just triggered conservative whining. You need to grow a thicker skin if you’re going to keep trying to pass off AI slop as your own writing.

from the tone and the poor grammar it’s clear that these comments don’t come from the same author. if you weren’t bothered by me pointing that out you wouldn’t keep responding with weak generic insults.

Fairly large temblors especially off crescent City which don’t happen often. Rock and roll.

I woke up suddenly about 2 mins before the 5.2 quake. Just a quick sharp jolt near Briceland. Apparently 7 miles outside the radius of the shake alert zone so no warning from MyShake app.

There was another one on the same spot as a couple of this morning’s, at 7:36 pm this evening (Wednesday). It was a 4.5. I felt that one, though not the earlier ones, here in the lower Mattole Valley.

Made it a day without another medium shaker. Now let us try two days.
