If you woke up just after midnight in Mexico City to the sound of those hauntingly familiar loudspeakers blaring the seismic alert, you aren't alone. It’s becoming a bit of a pattern lately. The earthquake today in mexico city was actually a moderate magnitude 5.0 (though some sensors initially pegged it at 5.2 or 5.3) that hit just past midnight on Friday, January 16, into the early hours of Saturday, January 17.
Honestly, the magnitude doesn't tell the whole story. While a 5.0 isn't usually enough to knock down walls, the proximity and the sheer depth of the seismic history in Guerrero make these tremors feel way more personal for those of us living in the capital.
What Actually Happened with the Earthquake Today in Mexico City
The epicenter was located about 17 kilometers southwest of San Marcos, Guerrero. That’s roughly 365 kilometers away from Mexico City. If you’re wondering why your bed was swaying despite the distance, blame the lakebed. The city is literally built on soft sediment that acts like a bowl of Jell-O.
President Claudia Sheinbaum was quick to post on social media, confirming that the National Civil Protection Coordination kicked off their standard protocols immediately. No major damage. No injuries reported. But let’s be real—the adrenaline spike is real when those alarms go off at 1:00 AM.
According to the National Seismological Service (SSN), this wasn't some random event. It’s part of a massive series of aftershocks following the 6.5 magnitude quake that rocked the region on January 2.
Why the Ground Won't Stop Shaking
Since that January 2nd event, there have been over 4,700 aftershocks. That is a staggering number. Most are too small for us to feel in the city, but today’s 5.0 was the biggest one yet.
Think of it like the Earth’s crust trying to find its seat after a giant chair-move. The Cocos Plate is constantly sliding under the North American Plate in what scientists call subduction. Sometimes it sticks. When it finally slips, we get what happened today.

The Guerrero Gap: The Elephant in the Room
There is a lot of chatter on social media about a "San Marcos Fault" or some new crack opening up. Experts have basically dismissed that. The real concern for seismologists like those at the UNAM Institute of Geophysics isn't a new fault, but rather the "Guerrero Gap."
This is a 150-kilometer stretch of the coast between Acapulco and Papanoa that hasn’t seen a massive, devastating earthquake in over a century. While today's earthquake was significant, it didn't happen in the "dead center" of that gap.
Some researchers argue that frequent 5.0 tremors are actually a good thing. They might release "slow-slip" energy. It’s like a pressure cooker letting out steam instead of exploding. But others aren't so sure. It’s a bit of a toss-up in the scientific community whether these small aftershocks prevent the "Big One" or are just noise before the storm.
How Mexico City Felt It
You might have noticed that some neighborhoods felt it and others didn't.
- Condesa and Roma: Usually the first to feel it due to the soil.
- Polanco: Moderate swaying.
- Tlalpan: Mostly quiet, though some residents reported their dogs barking minutes before.
It’s kinda fascinating how the SASSLA app or the official Alerta Sísmica gives us that 40-to-60 second lead time. It doesn't sound like much, but it's the difference between being in an elevator and being on the street.

Survival is About More Than Just a Go-Bag
We all have the backpacks by the door. But honestly, most of us forget to check them. After the earthquake today in mexico city, it's a good time to look at the basics again.
Water.
Batteries.
Copies of your ID.
Don't just keep them in a drawer. Keep them in a bag that you can grab without thinking. Also, if you’re using the SASSLA app, make sure your "Critical Alerts" are turned on in your phone settings. It’s common for people to realize their phone was on "Do Not Disturb" only after the shaking starts.
Actionable Steps for the Next 24 Hours
Aftershocks are still a high possibility. Since we've seen nearly 5,000 of them in two weeks, you should expect the ground to stay "fidgety."

- Check your gas lines. Even small tremors can loosen old fittings. Use the soapy water trick to look for bubbles on the valves.
- Re-tighten furniture. If you have heavy bookshelves in the Roma or Centro, check the wall anchors. Today’s 5.0 might have pulled them just enough to be dangerous next time.
- Download the official SSN app. Don't rely on Twitter or X rumors. People love to post fake videos from 2017 to get clicks.
- Talk to your neighbors. If you live in an apartment building, know who needs help on the stairs. The 67-year-old man who unfortunately passed away during the Jan 2nd quake died from a fall while evacuating, not from the building itself.
Stay alert. The seismic alert system is one of the best in the world, but it only works if you actually move when it speaks. Keep your shoes near the bed tonight.
