News here said it was felt in Salt Lake City. I didn't feel it though.

ShakeAlertLA will drop threshold for earthquake alerts, amid gripes people not alerted

Following the 6.4 magnitude earthquake that struck Southern California, Los Angeles will lower the notification threshold on its ShakeAlertLA app, alerting users when temblors of at least a 4.5 magnitude occur, the United States Geological Survey and Los Angeles city officials said Friday.

So, this aftershock is stronger than the first quake?

The way the system works—this 6.9 one is now the main earthquake, and the 6.4 one yesterday has been demoted to a foreshock.

Any weaker ones in the days to come, and there are bound to be some, will be aftershocks. But if there is a stronger one on the same fault—God forbid!—it will be considered the main earthquake, and this one will be demoted to a foreshock.

Make that aftershock a 5.5

I felt that one much stronger than the one on the 4th.

My kitchen floor was trembling and rolling, I had to lean against the counter because I felt unstable.

Hubby ran out of the bedroom saying we needed to go outside. I followed but I dont think it was necessary. lol

I grew up in L.A. I was always taught to never run outside. A wall could fall on you as the walls fall outwards. Air conditioners fall off roofs. In the 1971 quake, I remember cars bounced around and ended up blocking the road.

I was taught to get underneath the strongest piece of furniture like a kitchen table. I was also taught to keep beds away from windows and such.

As a result of hearing so much about earthquakes growing up I literally don't have glass picture frames in my house. I have all canvas pictures everywhere. So with the exception of a white board there is really nothing heavy on my walls.

A few weeks ago I was thinking about how I haven't felt an earthquake in so many years!

I was just running my hyena in Irvine Park next to the river. There are these large water main/hydrant looking things. There were three of them. I don't know what they are but they're taller than me and curve at the top ad have huge bolt things. I was running past and heard a super loud whooshing sound. I said, "What the hell was that?" I thought it could be a massive bird in the brush. Then I said, "sounds like those things are going to burst!"

A second later I passed another, smaller one and heard the wishing again, but different. My running partner didn't hear it and neither of us felt anything. Two seconds later my mom called to say we just had a big earthquake.

So strange. I think I heard it but didn't feel it!

YES! I was in a Target parking lot in Irvine, exiting the building not yet in my car. I didn't feel a thing but the parking lot lights were making a ruckus, clanging back and forth.

As a lifelong Southern Californian, I was trained the same way—walls collapse outward, glass shatters—don’t go outside until the shaking stops.

(I’m on a granite hillside in San Diego County, and I think I felt just a tiny twitch.) I hope you guys are all safe.

(For anyone who’s not in earthquake country—the scale goes up sharply, so a 6.9 is a LOT more violent than a 6.4.

So the NBA in Vegas stopped and postponed a game (NY vs NO) because the scoreboard was swinging during the quake. But the dodgers, in L.A. played through it.

You have a pet hyena?

Yes, I believe it's every 0.3 is twice as strong? So this was 4-5 x's stronger than yesterdays?

Dr. Lucy Jones is saying it was a 7.1 now.
I felt it pretty good and yesterdays too. I'm 1.5 hours north of you Wary. I haven't felt any todays aftershocks tho.

FYI - CNN, FoxNews and MSNBC are all offering live coverage.

I'm the AV and feeling a few aftershocks now

Hello neighbor. It was much stronger and longer tonight! In my location, yesterdays for-shock felt like a few jolts and then a rolling motion. Tonight's was mostly strong jolts and lasted longer, maybe 30 seconds. I'm about 70ish miles from the epicenter. My poor pups. Between the earthquakes and the firecrackers, they're a wreck! Praying for the folks in Ridgecrest and surrounding area's. I hear the little town of Trona got hit pretty hard too.

Now official second largest quake (July 4) in past 20 years.

That sounds about right. A 7 is ten times as much as a 6. So, since they revised this up to a 7.1–it’s even stronger.

And then, a lot depends on the type of soil you’ve built on, fill dirt and sandy soil being worse. And the direction of the force of the earthquake comes into play, too. So, a lot of variables.

California Earthquake: Multiple injuries and fires reported - CNN

Multiple fires and injuries have been reported in Ridgecrest -- about 150 miles from Los Angeles -- after Friday's earthquake, Kern County spokeswoman Megan Person told CNN. An emergency operations center is being set up in Bakersfield, she said.

In central Los Angeles, Friday's earthquake felt stronger than the one a day earlier, making buildings rock back and forth forcefully. Donald Castle, who lives in Porterville west of Ridgecrest, said his house shook for between 20 and 25 seconds.
