4.3 earthquake rattles Southern California

Brandon Mercer, SFGate

Updated 7:18 am, Saturday, July 25, 2015

FONTANA -- A 4.3 preliminary magnitude earthquake woke Southland residents up just before 6 a.m. Saturday, with shaking felt from the coast clear out to Palmdale.

The shallow quake was felt strongly in Fontana, with a population of over 150,000 people, and felt more weakly in Riverside and Long Beach, according to the U.S. Geological Survey automated shake maps.

Shallow quakes like Saturday's will be much more noticeable for their size than deeper quakes. The tremor struck at a depth of around 3 miles.

Twitter exploded with earthquake tweets but no damage was reported, despite sharp jolts being felt.

Besides the normal routine news organization and journalist tweets getting the quake news out, many reminded others about aftershocks or the possibility of this being a foreshock, which is always a geological possibility.

Melissa Skillens wrote, "Always stay cautious since a bigger Earthquake can come afterwards. Learned the hard way during La Habra quake."

Most others just complained--or embraced--the early alarm clock.

Grady O'Bryan þtweeted, "That was a nice wake up call," while Twitter user "The Dog's Mom" wrote, "No need for the baby to get me up at 6am. It was the earth."

Most of the energy must have went the other direction from the high desert because we are directly north of Fontana and all we got was a noise that we thought was the irrigation turning on.

HAH! I used to live in Fontana when I was growing up! And their location of the epicenter can't be right, unless it's changed in the past 30 years, but Fontana Ave, never crossed Sierra...So I'm thinking they may have mean Citrus. Which would have placed it just north of the High School.

I remember the last quake I was in was in Fontana. was like a 4.6 or so. We thought someone ran off Foothill blvd, and ran into our house...Was a quick BROOM!! and shudder. When we were outside looking at the house for damage or a smoking wreck of a car, we noticed two of our neighbors were doing the same. Then all of us chuckled, and went back in to finish watching ON tv (or maybe it was Select TV....so long ago)

There has recently been some activity up here (NO CAL) on the Hayward fault. Traditionally, historically, the Hayward fault moves after the San Andreas has a big one. The San Andreas moved big time in 1989. Maybe things are heating up?

Getting a little close to San Clemente and the nuke plant there.

SONGS (San Onofre Nuclear Generating Station) has been closed for a while. There is no power being created there any more (and the area feels the lack of jobs it provided), but there still is some nuclear waste that may be a concern in the event of an earthquake. Be interesting to know how much danger the old material would be. The plant is scheduled to be completely decommissioned by 2030. We'll all miss those big metal "boobies".

If you mean spent fuel rods, they're very "hot".

It used to be worse before the steel plant shut down. Of course they employed tons of people but at least the air quality is better.

I was raised in that area. I predate the high school having arrived in Fontana in 1943. The population was 3000. Now it is 150k. Hard for me to believe. Hated it then. Left there in 1956. I was in the first graduating class of Fontana High School. Our first class rooms were in school buses. Couldn't wait to get out of there and no desire to go back! And you are right...Fontana Ave and Sierra do not cross each other. I agree that they must have meant Citrus Ave.
