If you’re standing on the sand in Luquillo or sipping a coffee in Old San Juan right now, you’re probably asking one thing: is there a tsunami warning in puerto rico? As of today, January 15, 2026, the short answer is no. There are currently no active tsunami warnings, advisories, or watches for Puerto Rico or the U.S. Virgin Islands.
It’s a relief, honestly. But in a place where the ground likes to wiggle as much as it does here, staying "in the know" is basically a part-time job for locals and travelers alike.
The Puerto Rico Seismic Network (PRSN) and the National Tsunami Warning Center (NTWC) have both confirmed that coastal conditions remain normal. While a few small earthquakes were recorded earlier today—including a 3.1 magnitude tremor near Hatillo—none of these had the "oomph" required to move the ocean floor and trigger a wave.
Understanding the Current Tsunami Warning in Puerto Rico
When people search for "is there a tsunami warning in puerto rico," they’re usually looking for one of four specific messages. The system isn't just "safe" or "run." It's more nuanced than that.
The Information Statement is the most common. It’s basically the government saying, "Hey, we felt that quake too, but don't worry about the water." Then you have the Watch, which is the "heads up" phase where they’re still crunching the numbers. The Advisory is more serious; it means strong currents are coming, and you should probably get out of the water even if a giant wall of wave isn't visible. Finally, the Warning is the big one. That's when you move to high ground immediately.

Why the Caribbean Stays on High Alert
You might wonder why people get so jumpy about tsunamis in the Caribbean. We aren't the Pacific, right? Well, technically, the Puerto Rico Trench is the deepest part of the Atlantic Ocean. It’s a subduction zone where one tectonic plate is shoving itself under another.
Historically, the island has been hit hard. Most locals know the story of the 1918 San Fermín earthquake. A 7.1 magnitude quake triggered a tsunami that slammed into the western coast, specifically Aguadilla and Mayagüez. Waves reached up to 20 feet high. That’s why the Puerto Rico Seismic Network at the University of Puerto Rico at Mayagüez (UPRM) is so incredibly diligent. They remember what most of us have forgotten.
Real-Time Sources for Tsunami Alerts

- The Puerto Rico Seismic Network (Red Sísmica): This is the local authority. Their website is often the first to post specific coordinates for island-based tremors.
- Tsunami.gov: This is the official portal for the NOAA National Tsunami Warning Center. If there’s a threat to the U.S. territories, it’ll be listed here in bold letters.
- National Weather Service San Juan: Their Twitter (or X) feed is arguably the fastest way to get a notification on your phone.
Honestly, the "Caribe Wave" exercises held every March (there's one coming up on March 19, 2026) are a great reminder that the system is only as good as our response to it.
What to Actually Do if a Warning Drops
If the sirens go off or your phone starts screaming that terrifying emergency alert tone, you don't have time to pack a suitcase. You've got to move.
First, identify if you are in an Inundation Zone. Most coastal towns like Rincón, Dorado, and Humacao have blue signs with a person running uphill. Follow those. You don't need to drive to the center of the mountains; you just need to get above the predicted flood level—usually about 50 to 100 feet above sea level.
If you feel a quake that lasts more than 20 seconds or is so strong you can't stand up, don't wait for the official is there a tsunami warning in puerto rico notification. Just go. The "natural" warning—the shaking itself—is often faster than the electronic one.

Misconceptions About Puerto Rico Tsunamis
One big myth is that the water always recedes before a tsunami. Sometimes it does, and it looks like a dramatic low tide that exposes reefs and fish. If you see that, run. But sometimes the first sign is just a massive, churning surge of water that looks more like a rising tide on steroids than a crashing "surf" wave.
Another misconception? That tsunamis are just one wave. They aren't. They are a "wave train." The first one might be small, and the third one might be the killer. Stay on high ground until the PRSN or local police officially say it's safe to return.
How to Prepare Right Now
- Download the FEMA App: You can set your location to specific municipalities in Puerto Rico to get localized alerts.
- Check the Maps: Visit the PRSN website and look at the "Mapas de Desalojo" for your specific beach or town. Know your route before you need it.
- Have a Go-Bag: Keep a gallon of water, some snacks, and your ID near the door.
While there is no tsunami warning in puerto rico today, being ready for one is just part of living in paradise. We live on a beautiful, active island. Respecting the ocean means knowing when to step back from it.
The best thing you can do right now is save the Tsunami.gov link to your phone's home screen and verify your local sirens are working by checking with your municipal emergency management office (OMME). Stay safe out there and enjoy the beaches responsibly.
