3.9 Earthquake Shakes Dana Point and Laguna Niguel

Residents may have felt a weird sensation around 10:30 Monday morning in the area. The USGS is reporting a 3.9 earthquake. Where were you?

Did you feel a strange sensation Monday morning? It wasn't your imagination. A magnitude-3.9 earthquake struck about one mile west of San Juan Capistrano, according to the U.S. Geological Survey. The quake happened at 10:37 a.m. about two miles north-northeast of Dana Point and three miles south- southeast of Laguna Niguel. 

Locally, Pauline Colvin, Council Liaison/Communications Officer at said, "Yes, the quake was felt at City Hall and everything appears to be fine at this time."

Principal Tony Bogle said, "The Crown Valley  community experienced a small earthquake at approximately 10:40 AM this morning. The quake was centered in the San Juan Capistrano area and measured 3.9. The students evacuated the buildings and the site was checked for damage. All is well and the students were released back to the classrooms."

students and staff are doing fine after this morning’s earthquake, according to another message sent to parents. 

Principal Ellen Fine added that the students are also back in the classrooms and there was no damage.

Resident Tracy Buck said, "Yes, I felt it. The house creaked, and our dog Roscoe howled. Fast reporting, Deb, as usual! Thanks."

We felt it but it was very short. Nothing swayed, no pictures, etc. moved."

Another reader who goes by BBQ said, "We felt it but it was very short. Nothing swayed, no pictures, etc. moved."

Added Roy Maitland, "Crown Valley Business Park building rolled and light fixtures swayed back and forth."

Reader and blogger Valerie Burchfield Rhodes said, "My kids didn't feel it at Dana Hills High School but my 125-pound Golden Retriever wanted to jump in my lap here at my home office near LN/DP border."

The quake was reportedly felt as far away as Glendale, Riverside and Temecula.

Orange County Fire Authority Capt. Marc Stone said there were no reports of damage, but firefighters were going through their usual protocol following an earthquake to ensure the temblor caused no other problems. Orange County sheriff's officials also said there were no immediate calls for service related to the earthquake.

Officials at Southern California Edison said the quake Orange County had no impact on the San Onofre Nuclear Generation Station, which has been shut down since January for repair work.

Here is what the USGS has listed on its website:

  • 2 km (1 miles) W (259°) from San Juan Capistrano, CA
  • 3 km (2 miles) NNE (14°) from Dana Point, CA
  • 4 km (3 miles) SSE (159°) from Laguna Niguel, CA
  • 23 km (14 miles) SSE (155°) from Irvine, CA
  • 81 km (50 miles) SE (140°) from Los Angeles Civic Center, CA

I was standing in my kitchen, and thought it was thunder. Were you home? Did you feel it? Tell us in comments.

No aftershocks yet?

@Randy:No aftershocks, maybe they are waiting for the UFOs!

Debbie - or crashed "underground".

Randy: Or maybe in the caves!

Maybe too many people looking for a sale!

I've experienced A LOT of earthquakes, but this one was different -- nothing swayed or moved, just a loud noise that felt like the sound barrier was broken and a violent thud to my roof. Perhaps Camp Pendleton is conducting experiments again.

I still don't think it was an earthquake, it sounded and felt like a sonic boom. TWO loud booms each followed by a huge jolt. Read what the Huffington Post said about a similar event here: http://www.huffingtonpost.com/2012/04/22/sierra-nevada-meteor-loud-explosion-fireball_n_1444338.html?icid=maing-grid7%7Cmain5%7Cdl10%7Csec3_lnk3%26pLid%3D154392

USGS said there was an earthquake identified. Hmmm?
Debbie L. Sklar (Editor) April 24, 2012 at 03:53 PM
@Randy: Wonder if they can help us "identify" the UFOs?
Debbie L. Sklar (Editor) April 24, 2012 at 03:55 PM
@Ruby: That's what I thought, didn't seem like an earthquake to me either, I'm doing some research.
Ruby Starr April 24, 2012 at 03:56 PM
Hmmm, is right,...HAARP!!! Whenever a real earthquake occurs the media reports it. This time there was nothing.

@Ruby: I did!!!
randy April 24, 2012 at 04:25 PM
Debbie - perhaps they can help you connecting the dots. Seems there was no one saying a "meteor" or a "shootiing star" during the cloudy skies in OC yesterday. Did anyone else say from other remote cities witnessing the meteor shooting? It is rather interesting that USGS said the epicienter was "located" nearby Marina Hills and SJC although UCI professor explained a lot about the newer "hidden" fault under San Joaquin hills area. Isn't it a coincidence? :-)

That was the weirdest "earthquake" we've ever felt.
Debbie L. Sklar (Editor) April 24, 2012 at 05:15 PM
@Ruby: will check the link any special area of it?
Debbie L. Sklar (Editor) April 24, 2012 at 05:15 PM
@PC Mama: Any earthquake scares me.
Debbie L. Sklar (Editor) April 24, 2012 at 05:16 PM
Agree, not sure like you said if it really was one ..am doing some research, stay tuned.
Ruby Starr April 24, 2012 at 06:28 PM
You're entitled to believe whatever you like. Afterall, our government always tells the truth (and pigs can fly).
Skylark April 24, 2012 at 06:47 PM
I think it was a sonic boom just like what happened in Northern California the day before. I am waiting for the news to tell us that it was not actually an earthquake as reported. It was different than any earthquake I have ever felt. it was like an explosion. No gradual start and no gradual end. Just a BOOM and a rattling and shaking. And even those who felt it 20 miles away did not feel the rolling that you usually feel in an earthquake.
Debbie L. Sklar (Editor) April 24, 2012 at 07:00 PM
@Sky: Agree, am working in something right now.
randy April 24, 2012 at 07:18 PM
USGS had it clearly recorded and published data where was provided at precisely same location and time. Does it mean this new kind of earthquake behavior that being heard by everyone? It is interesting to note that Debbie Sklar was the one who talking/interviewing about that area in past weeks. People do share something in matter of days, weeks, months. You can read what she wrote. IMO, it is interesting that she decided to come up with something in particular before yesterday's reaction. Did USGS get the data from the precise location and epicenter independently with justification? :-)

I was upstairs & heard loud noise! The doors were shaking in my sisters room! Only lasted a few seconds. But my sister & her two kids felt it too! All the way in Aliso viejo. The kids couldn't stop saying Quake to me when they called. It kinda scared them but I told them it was ok.

HERE'S WHAT REALLY HAPPENED... http://www.msnbc.msn.com/id/44208437/ns/technology_and_science-space/t/superfast-military-plane-hit-mach-crash/#.T5hEaNX0mX0

"DARPA's experimental Hypersonic Technology Vehicle (HTV-2), lost significant portions of its outer skin and became uncontrollable after three minutes of sustained Mach 20 speed last August. That was the conclusion of an independent engineering review board investigating the cause of what DARPA calls a 'flight anomaly' in the second test flight of the HTV-2. Quoting the report: 'The resulting gaps created strong, impulsive shock waves around the vehicle as it traveled nearly 13,000 miles per hour, causing the vehicle to roll abruptly. Based on knowledge gained from the first flight in 2010 and incorporated into the second flight, the vehicle's aerodynamic stability allowed it to right itself successfully after several shockwave-induced rolls. Eventually, however, the severity of the continued disturbances finally exceeded the vehicle's ability to recover.'"

Interesting. Why above San Joaquin fault?
