Earthquake in Baja

Filed under: General — Patterico @ 3:46 pm



I just felt a very mild earthquake. I was the only one sitting down in the house and the only one to feel it.

Anyone else feel it?

UPDATE: Preliminary report: 6.9, centered in Baja.

UPDATE x2: L.A. Observed reports:

There’s now also been a 4.1 quake near The Geysers in Napa-Sonoma wine country.

And a 3.1, possible aftershock, in San Diego County 3 miles WSW of Julian.

UPDATE x3: L.A. Observed again:

And now a 4.5 magnitude quake near the border. Again likely an aftershock, at 4:09 p.m.

UPDATE x4: This report says it was a 7.2.

Here is a video of waves in a pool caused by the quake:

  1. Absolutely felt it, seemed like a long gentle swaying…no big jolt. Cal-Tech said it was 6.9, centered in Baja.

  2. oops, commented when you updated…

  3. I felt it. I was the only one sitting in the couch then I suddenly felt a mild swaying… But when I told my mom about she said she didn’t feel anything…

  4. Quite obviously an earthquake. From the damped, rolling groundwaves it was quite clearly some ways away and therefore quite powerful, especially considering the duration of about a minute. I felt it, my wife felt it and the cats felt it and were not happy.

    I note that the earthquake happened at 3:40 PDT and we felt it 3 minutes later.

  5. Hello Dana! and glad it wasn’t worse where you are. I hope we’ll get reports from our other southern southern Californians, like Bradley J. Fikes and Mike K, if he’s not in Arizona this weekend.

    In Santa Monica, the Baja quake was relatively gentle, but went on and on and on for a disquietingly long time.

  6. This USGS map shows the size and timing of earthquakes in that area. In a seismic sense, it’s a busy area.

  7. Well Gary…hey there, stranger! I was reading dozing off and rudely awakened. It did seem to last quite a long time. An overhead chandelier swayed for an even longer time. Glad too you are well on the west side. I hadn’t realized this but apparently Baja has been experiencing 3 pointers throughout the past week…

  8. Reporting from the SFV, we definitely felt it here. It was like being on rollers. I felt like I was being swirled. Nothing fell over, but the blinds danced a bit.

  9. Here in Long Beach, I was swaying and rolling. While walking towards the door, I felt like a drunkard, very unsteady on my feet (and no, I haven’t been drinking). Maybe it’s time to start…

  10. Mom called from Palm Desert. Her chandelier was swinging big arcs and the house was moving around quite a bit.

  11. We certainly felt it in Yuma. Think the location was about 70-90 miles away. We had just finished eating, all ran outside. Several trinkets fell and broke. It seemed to go on forever. And still feeling aftershocks. In fact, as I type this. Ocean front property soon!

  12. Now a 7.2… saw in the news people felt it up here in Santa Barbara… not me.
    Evidently I am insensitive… ask my wife what that means because I don’t get it.

  13. If California detaches will y’all form your own country? Please?

  14. I had the same reaction as Mr. Matamoros – was standing next to the kitchen sink, and thought I was having a nausea attack, then noticed the hanging lamp over the table going crazy – all this with no sound.

    A friend in Del Mar emailed that they had waves in their pool.

  15. also reporting from the SFV: we didn’t feel a thing.

  16. If California detaches will y’all form your own country? Please?

    I think only if it also splits north and south, too….Heck, they can even have Jerry Brown as their guv. A good will offering…we in the new southern Cali state won’t object!

  17. There seem to be several aftershocks up and down the California coast.

  18. I’ve lived in CA all my life so far. If an earthquake isn’t at least 5.0, I usually won’t notice it, and won’t wake up if it happens during the night.

    If it happens during the waking hours and isn’t at least a 6.0, I’ll typically ignore it.

  19. 42 significant aftershocks in a little over 4 hours. I didn’t feel it as I was walking around downtown San Diego at the time.

    After being in Milpitas during the earthquake in ’89, I usually don’t pay any attention to them unless it knocks me off my feet.

  20. This USGS map shows there have been 302 California and/or Baja earthquakes in the past week. Fortunately most of them were minor but, other than about a dozen, it looks like most occurred in the last 24 hours. That seems like a dramatic uptick in activity.

    On the other hand, I grew up in an area with lots of tornadoes. There were days with no tornadoes and other days with lots of tornadoes. I guess you can get used to almost anything, can’t you?

  21. This region is always pretty active. The area along the border from Tecate to Yuma typically has 30 to 60 micro quakes per week (up to about a 3.0). Occasionally, they are even strong enough to feel. 😎

    However, I can’t even remember the last time there was a 4.5 or higher in this region.

    I grew up in eastern Kansas so I can sympathize on the tornadoes. We used to sit out on the front porch and watch them coming toward us. More than a few days spent cutting up downed trees and branches, fixing fences and trying to track down the livestock. Oh, the good old days…8-)

  22. You can always hide from a tornado in the cellar; not especially where I would want to be during an earthquake.
