It’s actually much worse than that. A 7.5 has a magnitude, as measured on a seismogram, 1000 times greater than a 4.5. But the energy of a 7.5 earthquake is 32,000 times greater than a 4.5. The energy is what causes damage.

Felt it, but more like a rolling than a jolt like yesterday. This time I will be wearing clothes to bed to feel confident to run outside. It says 3.4 so I have my flashlight by me in-case.
It’s generally not advised to go outside during an earthquake. You’d be safer under a table/desk (Head and chest covered). Lots of broken limb type injuries from people who go outside, when debris from buildings, trees, power lines etc are toppled.

No did not feel it here in North Concord. Watching the Concord City Council Meeting Live. Apparently they did not feel it either at City Hall. No mention of it.

Felt that one too, but it was much more subtle than the 4.5 last night.

Felt it in Dana Estates. Compared to last night it was just a little “bump”. I hope it was an after and not a for-shock! Just in case I’m pulling the flashlights out that I just put away after last week’s PG&E threatened power outage!
Heard something rattle a little, but that was it. Dog raised his head, but no barking. Praying for no big ones!

Felt in Benicia – it was the first earthquake I’ve felt that didn’t roll or jerk side to side. Instead the dang bed jumped up and down and slammed on the floor. Friends in Vacaville also felt it

I’ve got the patio door open and it made a loud creak like someone bumped into it. The cat came over and stared at me like it’s my fault. lol 😂

I was at Sunvalley Mall in the lower level food court, didn’t feel a thing. I was with 4 adults, they didn’t feel it either.
@home, heard on second floor, from first floor. Not felt on first floor.
I’d rather have several small earthquakes instead of one big one 😉
I was sitting on the couch watching TV when I felt it. No big deal, just a slight bump. I actually thought it was the cat jumping up onto the couch, but she was sleeping on the floor and wasn’t disturbed by it. After last night’s shaker I found her hunkered down in the corner.

In the 1800s the Calaveras fault moved big time, guesses were probably 7-8+ as the Richter scale wasnt used yet.
So yes Concord area sitting right on the Calaveras fault will be devastating when it happens.
Glad we rent, so we can just leave when the house we are in gets totalled.
Quake Guy, Concord is sitting on top of the Concord Fault, which is a branch of the Calaveras Fault, and the Calaveras Fault is a branch of the San Andreas Fault.
And who’s fault is that certainly not mine…
It was Calaveras fault that moved and it wasnt Concord fault. I was talking about Calaveras I don’t care what Concord is sitting on top of or what under it branches off what.
The one the other night at 10:30 p.m. startled me. I was just going to bed.
I wasn’t sure if I should get out of bed and duck and cover but instead stayed in bed and covered my bed with my bed sheets (like that would have done any good to protect me – LOL). I was cooking dinner last night when the 3.4 hit. I questioned whether I actually felt something since it was just a quick roll. I was told 2 minutes later that we had an earthquake. Thank goodness it wasn’t any stronger. Wondering if earthquake #3 is coming since things seem to come in 3s.
Yep. Small, though. Any info?
Thanks for the update.
Felt it pretty good here in Martinez. Not nearly as strong as the one yesterday thought.
Yep
Yes
Yep
Yes, felt it in State streets. Real quick jolt!
Oh yes! I felt 2 small jolts.
Definitely felt it!! I’m getting nervous!!
Felt in Canterbury village
Felt it in Benicia. A little back n forth one.
It felt tiny. Like a baby earthquake
Heard and felt it here, Concord/Clayton border
Yes! Felt it by monument and Detroit in Concord.
definitely just did! along with my coworkers.
A 7.5 earthquake is 1000 x more powerful than a 4.5. Imagine that for a second.
It’s actually much worse than that. A 7.5 has a magnitude, as measured on a seismogram, 1000 times greater than a 4.5. But the energy of a 7.5 earthquake is 32,000 times greater than a 4.5. The energy is what causes damage.

I’m in North Concord and definitely felt it.
It felt like a Good Roll coming from South to North, something I also felt a few years ago, here tonight at DVC area. It was substantial.
Felt it at Treat & Oak Grove
Yes felt it! By Denkinger and Treat.
Yes I’m scared. It’ll be 30 yrs.. 1989 was the big one. I was scared then too.
A 3.4, I was making a cup of coffee in the kitchen. Similar quake to last night though milder. Tis the season.
Did not feel it in Brentwood
Quick jolt at Great and Oak Grove. @concord: the USGS said it is an unmapped fault.
Yep. For the second time in 24 hours the cats are mad at me. “Why the heck do you do that? That scares us to death!”.
A little thing in the room jiggled. The cat just looked at it. He didn’t dive under the bed like he did last night.
Earthquakes, explosions and fire. Sounds like the dang apocalypse down there in Claycord! You guys start hearing trumpets, best say your prayers.
ROFL

Two sharp jolts. A mile (ish) NE of Todos Santos.
The one the night before was much stronger.
Dear Mother Nature – Enough already… please
Didn’t feel it, but definitely heard it. Sure enough, the chandelier was swinging.
