Two earthquakes were recorded in Los Angeles early Monday morning, with no immediate reports of injuries or damage.

The Los Angeles Times reported that a magnitude 3.3 quake struck around 4:15 a.m., and was followed 29 minutes later by a magnitude 4.4 earthquake. Both of the quakes were recorded in the Lennox area, according to the Times, and were followed by several smaller aftershocks.

Lucy Jones, a seismologist and founder of the California-based Dr. Lucy Jones Center, reported on Twitter that the quakes were likely at least 12 miles deep, which contributed to the lack of reported damage.

"The M4.0 that just happened was under Lennox, CA, near Inglewood. Very deep at 20 km, so everyone is at least 20 km away. Would have been felt by most people awake in LA," she tweeted.

1. These are pretty small occurrences for Los Angeles.

You'd really have to be right on top of them to feel them.

2. Slept through it in Hollywood. nt

3. i was up when they happened...

...my sleep cycle has been outta whack for six months or more, so I've been getting up at 2:00 a.m. (PDT), was watching a movie and then all of a sudden things started pitching and groaning, shaking and rattling. Been through these before many times, and this one rolled for several seconds (felt longer), then poof all gone and all quiet, a few darking bogs nothing to see here move along.

4. Woke me and my wife.

For me it was a little rumble and shake lasting a few seconds. Alley woke and asked what was that? Neither of us felt a second quake.

5. We in NYC rarely ever feel an 😧 earthquake

So I was asleep in the morning around 30 years ago - dreaming I was on a elevator with other people.
Nothing unusual (I often have fairly wild dreams) until the elevator started swaying sideways.

I woke as I bolted up in bed yelling "Earrhhquake!!!!!".

I heard a deep rumble fade away, and maybe a faint vibration. But this didn't concern me because Our
apt building was built partly on a steep hill upheld by a gigantic base of cement, and Rock Boulders embedded in it! It also had a Big Balcony that jutted out from the building surrounding it.

This balcony acted like a sound amplifier! A basketball being bounced on the sidewalk sounded like gunshots. Any trucks would really rumble, and we often felt some vibrations.

So I looked around, nothing was amiss. So I figured it was a Truck. I went back to sleep.

When I woke up later I switched on one of my usual
Rock Stations that was in the middle of playing...

wait for it...

"Shake, Rattle, and Roll"! 😄
Afterwards the DJ says, "who felt that Earthquake
this morning!?!".
Whaaaaa!?!??! 😮

Omg, it was a frikkin' Earthquake, and my Subconscious recognized it!
I think it was 10+ miles above the city boundary in The Bronx. I was living in way, way upper Manhattan (the western side of "The Heights" ).


Hopefully my one and only! 🤞🤞🤞🤞🤞

6. Anything 4 and under is a "baby quake", however ...

These recent quakes in LA were 12 miles under, which means they were felt over a wide area.

OTOH, seems to me the deep ones are of a more rolling motion, whereas the ones closer to the surface can be sharper jolts. I base this on my experiences living for the past 60 or so years in the SF Bay Area, not on any professional seismologist findings.
