A powerful earthquake struck the eastern Mediterranean, rattling Crete and its neighboring islands in the early hours of Wednesday. Measuring 6.1 on the Richter scale, the tremor sent shockwaves across the region, prompting Greek authorities to issue a precautionary tsunami warning. The epicenter, located near the islands of Kasos and Karpathos, has heightened vigilance among residents and tourists. No injuries or significant damage have been reported, but the event underscores Crete’s position as one of Europe’s most seismically active zones.
The quake, felt as far away as Egypt and Israel, has raised questions about travel safety to Greece’s largest island, a popular holiday destination. Authorities are urging visitors and locals to stay away from coastal areas and monitor updates. The incident has sparked discussions about preparedness in a region prone to seismic activity.
Key actions for travelers and residents include:
- Move to higher ground and avoid coastal areas until the tsunami warning is lifted.
- Monitor local news and official alerts from Greek authorities.
- Follow safety instructions from the Ministry for Climate Crisis and Civil Protection.
- Check with airlines and travel providers for any itinerary changes.
With Crete’s rich history, stunning beaches, and vibrant tourism scene, the earthquake serves as a reminder of the natural risks that accompany its allure. The situation remains fluid as officials assess the aftermath.
Epicenter near Kasos and Karpathos
The earthquake’s epicenter was pinpointed 20 kilometers south of Kasos, a small Dodecanese island known for its tranquil charm. With a focal depth of 64.4 kilometers, the quake’s effects were felt across Crete, Rhodes, and Kos, but its deep origin reduced the likelihood of widespread damage. The Athens Geodynamic Institute initially reported a magnitude of 5.9, later revised to 6.1, reflecting the event’s significant strength. The German Research Centre for Geosciences confirmed the tremor’s reach, noting its impact in Israel, Syria, and Egypt.
Kasos, with a population of around 1,000, and Karpathos, known for its traditional villages, experienced the quake’s strongest effects. Despite the intensity, no structural damage or casualties were reported on either island. The deep nature of the earthquake, as explained by geology professor Efthymios Lekkas, typically results in singular events without significant aftershocks, offering some reassurance to the region.
Tsunami warning issued
Greek authorities acted swiftly, issuing a tsunami alert through the Ministry for Climate Crisis and Civil Protection. An emergency message via the 112 system urged residents and tourists to move away from coastal areas due to the risk of a tsunami. The ministry’s X post stated: “A magnitude 5.9 earthquake occurred 48km SE of Kasos. Risk of a possible Tsunami in your area. Move away from the coast immediately.” The warning was later updated to reflect the quake’s revised magnitude of 6.0.
The ministry emphasized that not all earthquakes trigger tsunamis, but vigilance is critical. A significant rise or fall in water levels can signal an impending tsunami, which may arrive as a series of waves rather than a single event. Tourists were advised to avoid watching waves from the shore, as this could be dangerous. The alert remains in place as authorities monitor coastal conditions.
Here are key tsunami safety tips:
- Seek higher ground immediately if you feel a tremor near the coast.
- Avoid beaches and low-lying areas until authorities declare the area safe.
- Stay informed through official channels, such as the 112 emergency service.
- Do not return to coastal areas until the all-clear is given.
Crete’s seismic history
Crete’s location at the convergence of the African and Eurasian tectonic plates makes it a hotspot for earthquakes. The island has experienced significant tremors in the past, including a 6.3-magnitude quake in October 2021 that caused minor damage and a 6.4-magnitude event in the same month near Karpathos. Earlier, in 2006, a 6.7-magnitude quake south of Crete sent tremors through mainland Greece. These events highlight the region’s ongoing seismic activity.
One of the most devastating earthquakes in Crete’s history occurred in 365 AD, destroying much of the island and triggering a tsunami that affected the Mediterranean. The island’s geological position along the Greek arc, where tectonic plates collide, ensures that seismic events remain a constant concern. Despite this, Crete’s infrastructure is designed to withstand moderate quakes, and no major damage has been reported from the latest event.

Travel safety reassurances
The UK’s Foreign, Commonwealth & Development Office has not issued travel advisories for Crete or Greece, indicating that it is still considered safe to visit. Travelers planning trips to the east coast of Crete, Kasos, or Karpathos are advised to stay updated through Greek authorities. The absence of reported injuries or property damage has bolstered confidence, but vigilance remains essential, particularly in coastal areas.
Crete attracts around 5 million visitors annually, drawn to its historical sites like Knossos, scenic beaches, and natural wonders such as Samaria Gorge. The gorge, a popular hiking destination, was temporarily closed to check for rockfalls following the quake. Authorities are conducting inspections to ensure the safety of tourist sites, with updates expected as assessments continue.
Flight operations unaffected
Flight schedules to and from Crete and nearby islands have largely remained intact. Heraklion International Airport, a major hub on Crete, reported no cancellations or disruptions. Similarly, Kasos Island Airport, which operates limited domestic flights with Olympic Air, and Karpathos Island Airport have continued normal operations, according to FlightRadar data. Rhodes International Airport experienced minor delays, but air travel in the region has been minimally impacted.
Travelers are encouraged to:
- Confirm flight statuses with airlines before departure.
- Monitor airport websites for real-time updates on schedules.
- Contact travel providers for assistance with itinerary changes.
- Keep emergency contact numbers for airlines and embassies handy.
The stability of air travel has provided reassurance for tourists, many of whom are proceeding with their plans to visit Crete and the Dodecanese islands.
Cancellation and insurance options
As no travel warnings have been issued by foreign offices, holidaymakers seeking to cancel trips to Crete are unlikely to receive full refunds under standard policies. Cancellation terms depend on individual holiday providers, and travelers are advised to contact them directly to explore postponement options. Companies are not obligated to refund bookings canceled due to personal safety concerns unless official advisories change.
Some travel insurance policies include coverage for natural disasters that prevent reaching a destination. Policies vary, and travelers should review terms carefully to understand their options. For example, certain insurers may cover cancellations if a tsunami or significant aftershocks disrupt travel plans. Consulting with insurers is recommended to clarify coverage details.
Regional seismic activity
Greece’s position along multiple tectonic fault lines makes it one of the most earthquake-prone countries in Europe. The recent quake near Kasos is unrelated to earlier seismic activity in Santorini, where over 555 tremors were recorded between January and February 2025. Those events, centered between Santorini and Amorgos, prompted school closures and evacuations. Geology experts have clarified that the Crete quake operates within a distinct geodynamic framework along the Greek arc.
The Aegean Sea plate’s subduction beneath the African plate drives frequent tremors in the region. While most are minor, the risk of stronger quakes persists. The South Aegean Regional Fire Department remains on alert, with rescue teams ready to respond to potential aftershocks. Authorities are also monitoring the Santorini caldera, though current activity is not linked to volcanic risks.
Tourism industry response
Crete’s tourism sector, a cornerstone of Greece’s economy, is adapting to the quake’s aftermath. Hoteliers and tour operators are reassuring guests that the island remains open for business, with no major disruptions to accommodations or attractions. Some operators are offering flexible booking options to ease concerns, though widespread cancellations have not been reported.
The earthquake’s timing, ahead of the peak summer season, has prompted industry leaders to emphasize preparedness. Greece’s robust emergency response infrastructure, including the 112 alert system, has been highlighted as a key asset. Tourism boards are working to maintain confidence, promoting Crete’s cultural and natural attractions while addressing safety concerns.
Local community measures
Residents of Kasos, Karpathos, and Crete’s eastern coast have been proactive in following safety protocols. Community leaders are coordinating with emergency services to ensure residents are informed and prepared. Schools and public buildings in affected areas are being inspected for structural integrity, though no issues have been reported.
Local authorities have distributed safety guidelines, emphasizing:
- Staying away from old or abandoned buildings during tremors.
- Avoiding large indoor gatherings to reduce panic risks.
- Keeping emergency kits with essentials like water and first-aid supplies.
- Registering with the Greek Emergency Communications Service for alerts.
These measures reflect the region’s experience with seismic events and its commitment to public safety.
International response
Foreign embassies, including the U.S. Mission in Greece, have advised citizens to follow local instructions and monitor media for updates. The U.S. Embassy highlighted resources like the Greek Ministry of Climate Crisis and Civil Protection’s website, which provides earthquake safety tips. Travelers are encouraged to register with emergency communication services for SMS, email, or voicemail alerts.
Other countries, including Australia and Canada, have echoed similar advice, urging tourists to stay informed. The lack of travel advisories from major governments has helped maintain Greece’s status as a safe destination, though travelers are cautioned to remain cautious near coastal areas.
Preparedness for future events
Greece’s advanced seismic monitoring systems, managed by institutions like the Athens Geodynamic Institute, play a critical role in tracking activity. The country’s My Safety Plan map, developed by the Ministry of Digital Governance, identifies rally points for natural disasters. These tools, combined with public education campaigns, enhance resilience in earthquake-prone regions.
Travelers are advised to:
- Familiarize themselves with hotel evacuation routes.
- Save emergency numbers, such as 112, for quick access.
