Yep, dog wasn’t too thrilled about it.
Initial report was 4.0 and about 25 miles east. They were WAAAAY off. 😂
We live at Alderpoint And upper sawmill. our house shook so violently everywhere, pictures falling off the wall.! oh my God That’s so much bigger than 5.1!
Wow! That’s the worst effects I’ve heard so far.
You’re probably either on a ridge or on a minor fault line that was jarred by the quake. Ridge lines amplify the shock waves if they are in the right alignment to the direction of the waves.
Yes..a big smack in Redway.
Rumbling roll followed by a large jerk and a loud cracking sound. A bit different than the normal quake here in sheltercove.
Right! Super loud rattling of the house, but didn’t feel the movement.. Ap area..
Ooph.. Don’t like that you heard a loud cracking sound. Not surprised though- was very jerky in downtown Redway.
Looks like all of California moved a bit yesterday. Almost as much as the whole week before.

Oh yeah! It was a classic opportunity to practice a ‘duck and cover’ maneuver. I didn’t though because the first soft bump faded out for a few seconds before the bigger jolts hit!
Note to self: ‘If there is a warning, forget your ego, and your, ‘No worries! I’m California cool’, and get under the table!’ (But wait! The table has a glass top. Now what??? lol).
Thanks for jumping right on this Kym!
You brace yourself in a doorway.
Safest place would be outside if you got the chance.
In most cases, the safest place is NOT outside. Most of our buildings are made better than Florida condominiums so find a solid surface, duck and cover. There’s so many dangerous things that can fall on you outside!
Go outside in Honeydew. Look up.
Go outside in San Francisco. Look up.
Depends where you are, huh.
Yes, I am with you in that 100% but I can only recall one quake that lasted long enough for me to decide I should leave the house. I got outside where I saw the trees rolling with it. Early 2000’s, GBV area.
Most are over before I ever felt like I had to duck or run.
My house did jolt and creak last night. I wonder was I woken by a first one to experience a 2nd quake since I jumped up from a dead sleep and had to think if I should leave the house? (I decided not to, fell back asleep).
“I’m California Cool”.
Heh. Sometime in the early 70s, I was in the old Library in the basement of the Courthouse in Eureka. A real shaker happened. Everyone stopped what they were doing, waited to see if it continued. It stopped and everyone went back to what they were doing.
These days, I’d have been out of there. Nearly 30 years ago, there was a fairly big one that originated up nearer Salem, NE of there. Anyway, the hanging lights in the office I worked in started wildly swinging. This was a second floor office built on piers over the bay on the central Oregon coast. The non-California raised people weren’t sure what to do.
I, from the large structural door frame (which I didn’t even realize I had moved to), said, “How about we grab the dog and GTFO? And move up the hill while we were at it”, thinking about the potential for a Tsunami. (though later found out the earthquake centered quite a ways inland and over a hundred miles away).
That triple junction where this happened last night. I tried to find which part was responsible, the SAF, the CSZ, or something along the fracture.
Big enough to think; should I stay or should I run?
Do not run. In fact, if it’s a big one, you can’t run; you will be thrown.
Ha! Reminds me of the 6.5 we had in 2010. I was living in an old farmhouse outside of Ferndale. When I realized it was going to be a big one I ran down the stairs and tried to jump off the porch. I’d make a leap and land right back where I started. Tried two or three times and finally just held onto a porch post until it subsided.
Yeah, in a big one you don’t really get to pick and choose what you’re going to do!
That’s no lie. In 92 I was trying to get myself and my neice to a safe spot in the house but every time I took a step it slammed us backwards, Crazy..
The first report said 4.0 located 20km ssw of Scotia. In the map the yellow. Red must be the 5.1
I saw that too, and I still believe it ☺
My doggo and I felt it. It really shook quite hard, but we stayed in bed.
My house has been through many quakes since 1953 with zero damage. We are waiting for the giant subduction event 😁
Felt it not in Freshwater
No…do not brace yourself in a doorway. That is no longer recommended as it is now a weaker area in modern houses and if there is an actual door attached that increases your chances of injury.
We will agree to disagree.
Door frame has a header above it supported by jack studs and king studs. And I’d much rather have a door swing into me than a 50 lb sheet of drywall falling on my head.
Actually doorways no longer require headers and kingstuds. If you house is built before 2000 then it is still that way, but after the early 2000s they started only doubling up 2×4 studs in door ways. Things have changed and not for the good. Google modern house collapse the weak spots are now doors and windows. No more 4×12 headers used above windows and doors in today’s houses.
Not true I’m a framer of 30 years minimum 4×4 header above door on a 2×4 wall, and 4×6 turned sideways on a 2×6 wall. Windows depends on the span, no more double king stud unless you plan on having wide casing so that your switches will clear. You can double 2×4 for a header on interior walls as long as it’s not bearing. We go by ubc (universal building code)
Steel stud framing is a bit different
If your ready my comment it’s said 2×4 doubled up, wich is stronger than a single 4×4. Just stating facts houses are not what they used to be…
Honest inquiry: what about a 100+ yr house (not victorian) in Eureka surrounded by 4-6 ft. diameter redwoods? Yes, that is my home. Door frame? Outside looking up to see which branches are falling through the roof? Or worst case, which tree may tip?
Although, we never felt it this time. Thought the Dog was barking at the bear that’s been around lately.
Felt it in willits
We’re Rock’in in Rohnerville.
Yump, Gville felt a little more rolling and sliding to me. Not so much of a shake.
That was a fast jerker..tossed stuff off my high headboard but that was it..
Any damage reported.
I counted 7 hard jerks east to west…in white thorn
Are we still talking about the earthquake?
😳 😳 😳
Lol!
Felt it big time in carlotta
My dog totally called it.
Felt it in Fortuna, the house shuddered a bit, don’t think there was any damage.
Never felt it at all in Blue Lake, and that’s fine with me.
Long lasting, maybe ten to fifteen seconds but smooth not violent shaking near college of the redwoods. Usually indicative of a fairly large quake some distance away.
Weird! We didn’t feel it at all in Ferndale, and our dog who gets worried easily by storms and fireworks, never came and started bugging us in bed.None of our hanging paintings have been shifted either. Those usually make a good indicator of ground motion here.
Nothing in Eureka… or slept through it.
We felt it in Willits. I thought it was much closer.
Had a jolt here in covelo
The way my bed shook, I thought my dog was having some bad dreams, then I remembered I don’t have a dog…
It was a series of rolls over here on Fruitland. Not bad for a bumpy ride but it seemed to go on forever.
Felt it in Dinsmore. Thought my bf was pulling a prank and shaking the bed
In arcata, bed shook but that was the extent.
Slept right thru it
I was watching a movie in the Fortuna theater. It made us look at each other and say “earthquake!”.
Felt like a car hit my home in Shelter Cove. First a loud CRACK!, and then a side jerk. Knocked stuff off the shelves.. one broken glass vase. Set off a car alarm at Black Sands Beach parking lot!
We built this house for Rock N Roll!!
When we were building in the early 90’s the Centerville Quake struck. The street rolled like ocean waves . My brother in law’s trailer was knocked off the stands. Next day his drinking buddy snuck up early in the morning and shook his trailer … Bro in law shot out of the door real fast!
Wow! That’s intense.
I remember watching the ground roll in waves during the 1980 7.0. Weirdest thing about it was it was 1:20 in the morning and there were no street lights where I was at, yet I could see three-foot high waves racing towards me and the trees whipping back and forth.
Everything was lit from the ground up by a weird bluish-green light. It was weird as f**k.
Wrote a whole story about it.
Link please!
Wow, I didn’t even feel it here in Rio Dell. I must have slept right through it. As far as I know my dog didn’t even wake up, but I must have been out for the count
Woke me up in Little River.
felt it out here on south fork mtn near mad river.. glad i wasn’t asleep yet, would have been a bummer if i’d missed it.. i really dig feelin the earth shake
Woke up, checked LCO, went back asleep.
pretty strong Earthquake vibe day before yesterday. Mentioned it to my wife.
It woke me last night, but it was a pretty gentle rumbling roller, it seemed to last a while, the house just creaked a little and popped once. We are on pretty solid ground here.
My initial estimate was a 5.5. I knew it was bigger than a 4.
I figured it was too easy a guess to say it was west of Petrolia, but I couldn’t come up with anything else.
I didn’t even think tsunami.
We felt it down here in leggett, good rattle and jolt, but these old houses were built to with stand quakes. Neighbor was high on mushrooms watching marvel movies, thought captain America was coming in his door.
Another excellent site for information about quakes is this one:

Weott.
Concrete pad floor.
In five years I’ve only felt two shakes. Big difference from the pole structure I lived in west of Redway — like during the Triple Shakes from the 90s (so glad that didn’t happen in the deep, soggy winter!). We noticed the Loma Prieta quake there, too.
Here, we’re also up the hill a bit, on solid ground.
There was a rumble and some squeaking (structural, I’m sure) and my bed felt like someone shoved it (west to east) two or three times. Rumble stopped, my bed was where I generally have it (as in it didn’t actually shift position). I looked at my clock and started counting, waiting for another rumble (larger, in my expectations) and when a couple minutes passed I turned on my computer and looked for it online.
By that time the “earthquake detectors” (pretties that hang from windows and ceiling) were no longer swaying.
I might not have noticed it if I’d actually been asleep. Still, I remember the ones that have cleared shelves and moved furniture, motivated the refrigerator to take a short walk… I am totally sympathetic to those who experienced damage and figure I’m just lucky to be where I am.
And my gut tells me this ain’t gonna be the last one we get this year.
We actually get several hundred every year. Just can’t feel them. You’re probably right about a bigger one, though. It’s been eleven years since we had one of any decent size, and 321 years since the last subduction ‘quake.
We’re due.
Felt one almost nearly imperceptible roll motion of the building (south to north) didn’t think much of it. Looked it up this morning. Glad to hear nothing is burning up or collapsed down in SoHum. There were alot of hard quakes down that way between 89 and 96. Haven’t really felt one like those since. Everybody felt 89
No one felt anything here in ’89. That was the Bay Area. We had our big ones in ’80, ’92 (three within 24 hours), and ’93. Those were all 7.0 or better. In 2010 we had a 6.5 that was a pretty good shaker.
I guess my sense of humor was a little too much for Kim. First time I ever posted anything and it was taken down quickly. Lighten up Kim !!!
Not really into scatological comments.
Well, shit.
Looks like it reappeared love you all !
NoBody had a classic heckle , seems like most commentators missed it…. 🤣
😬
Something like, -tsunami probably would’ve hit by the time they said no tsunami-?
I’d say a 5.1 tickled Humboldt’s toes. Around here, if it ain’t a 7.0, it ain’t a quake (but then I’ve been through five 7.0s, and a 6.5, so some of these youngsters around here might not feel the same).
A 7 offshore of here would feel like a 6 onshore unless you’re on a ridge, a connecting fault, or liquefying soil.
I was 2 miles from the epicenter in the Santa Cruz quake, up in the Soquel mountains. Barely got out of the house I was in before the massive stone fireplace sort of exploded all across the room I was in. A very large TV flew past me in the air vertically and smashed to pieces on furniture maybe 15 feet from where it was. Went back a week later and helped pried out pieces of broken dinner plates that had flown out of the closed cupboards so hard they had embedded 3/4s to 1+ inch into the plywood subfloor. Could have been someone’s skull. The ground felt like a moving river for 2 weeks. I think the mountains grew 6 ft. taller IIRC.
After seeing those dinner plate pieces embedded in the floor I almost always try to get out if I think it’s going to be big.
