You’ve seen the postcards. The blue domes, the white walls, the sunsets that make you want to quit your job and move to Greece forever. But here’s the thing: Santorini is literally built on a volcano. It’s gorgeous, but it’s restless.
Most travelers don’t think about seismic activity until the floor starts shaking. Honestly, that’s the worst time to start googling where to go. While the 2025 earthquake swarm—which saw over 12,000 tremors—eventually calmed down, it was a massive wake-up call. If you’re heading to the island, you need to know about earthquake in santorini emergency resources before you ever set foot on a ferry.
The island is safe, don't get me wrong. But being "safe" in a tectonic zone means being prepared.
The Numbers You Actually Need (Save Them Now)
Forget memorizing every local precinct. If things go sideways, you only need a few digits. Most people think they need a specific "Santorini-only" line. Nope. Basically, the European emergency number 112 is your best friend. It works even if your phone doesn't have a SIM or if you're out of credit.
- General Emergency: 112 (Multi-language support, very reliable)
- Police (Fira): +30 22860 22649
- Fire Department: 199 or +30 22860 33199
- Medical Emergencies (EKAB): 166
- Santorini Hospital (Fira): +30 22863 60300
- Port Authority: +30 22860 22239
If you’re staying in a smaller village like Oia or Pyrgos, your hotel will have local medical clinic numbers. Grab them at check-in. It takes two seconds.
Earthquake in Santorini Emergency Resources: The Reality of Civil Protection
Greece doesn't mess around with civil protection. The Ministry of Climate Crisis and Civil Protection runs the show. During the 2025 crisis, they activated the "Xenokratis" plan. That’s a fancy name for a massive, coordinated response.
You’ve probably seen the SMS alerts if you’ve traveled in Europe. In Santorini, these are critical. If an earthquake triggers a landslide risk or a (rare) tsunami warning, every phone on the island will scream at once. It’s loud. It’s scary. But it’s there to save you. You don't need to register; if you're connected to a local tower, you'll get it.
Where Should You Actually Go?
The biggest misconception? That you should run to the port.

Actually, in a major quake, the ports—especially Athinios and the Old Port of Fira—are the most dangerous places. Why? Landslides. Those towering caldera cliffs are made of volcanic ash and pumice. They crumble. During the 2025 tremors, authorities cordoned off Ammoudi and the Old Port specifically because of rockfall risks.
If the ground shakes, stay away from the cliff edge. Head inland to open spaces. Places like the Kamari or Perissa beach areas are generally safer because they are flat and away from the unstable caldera walls.
Understanding the "Red Zones"
Not every part of Santorini reacts the same to a tremor. The "Red Zones" aren't usually marked on tourist maps, but locals know them well.
- The Caldera Edge: Stunning views, high risk. The paths between Fira and Oia can experience "slumping."
- Old Masonry Buildings: Those charming 100-year-old stone houses? They aren't built to modern anti-seismic codes. If you're in one, get out to an open street immediately.
- The Ports: As mentioned, avoid these until official word says they're clear.
What to Do If the Shaking Starts
You’re in your hotel room. The glasses start clinking. Then the floor rolls.
Drop, Cover, and Hold On. Don’t run outside if you’re in a modern concrete hotel; the stairs are often the first thing to fail. Get under a sturdy table. Stay away from those massive glass windows that overlook the volcano. They look great, but they shatter easily under stress.
If you are outside, move away from buildings. In Santorini, "outside" often means a narrow cobblestone alley. That’s a trap. Roof tiles and balconies are the biggest killers in Greek earthquakes. Find a square. Find a field. Get to the middle of the street if it's wide enough.
The Volcanic Question
People always ask: "Is the earthquake a sign the volcano is blowing up?"
Usually, no. Seismologists like Efthymios Lekkas (who heads the Greek Earthquake Planning and Protection Organization) are very clear that tectonic quakes—the most common kind in the Aegean—are different from volcanic ones. In early 2025, there were thousands of quakes, but the "deformation" of the volcano didn't change. It stayed quiet.
However, the earthquake in santorini emergency resources include specialized monitoring by the Institute for the Study and Monitoring of the Santorini Volcano (ISMOSAV). They have sensors all over the island. If the volcano actually wakes up, you’ll know well in advance through the 112 system.
Actionable Steps for Your Trip
Don't let the fear of "the big one" ruin your vacation. Just be smarter than the average tourist.
- Download Offline Maps: If cell towers go down, you need to know how to walk to an open area without Google Maps.
- Pack a "Go Bag" Lite: Keep your passport, some cash, and a portable power bank in one spot. If you have to leave your room at 3 AM, you want to grab one thing and go.
- Check the "Civil Protection" Signs: Most public buildings and large hotels have evacuation maps. Actually look at them.
- Trust the Ferry Operators: If the island needs to be evacuated, the ferries are the lifeline. Companies like Blue Star and Seajets work directly with the Coast Guard. They’ll prioritize people at the safe muster points, not people standing on a crumbling cliff.
Honestly, the most likely "emergency" you'll face is a flight delay or a ferry cancellation due to a minor tremor. Stay calm, listen to the local authorities, and keep those emergency numbers saved in your phone.
Next Steps:
Before you leave for the airport, take a screenshot of the emergency numbers listed above and save them to a "Favorites" album in your phone gallery so they are accessible even without data. Then, check the official Greek Civil Protection website for any active "State of Emergency" alerts for the Cyclades region.
