What’s Causing All The Earthquakes In Greece, And Should Travelers Be Concerned

Summer is almost here, and most of us are counting down the days until we can set our out-of-office messages and head to the beach. But if Greece is on your travel list, you might be wondering what’s going on with all the recent earthquakes—and whether it’s still safe to go.

From late January through mid-April, the island of Santorini was placed under a state of emergency after hundreds of earthquakes struck with no clear explanation. The activity raised concerns about potential volcanic unrest, especially given Santorini’s well-known caldera.

Then, on May 22, another major quake hit Crete. The 6.1-magnitude tremor shook the island early in the morning at 6:19 AM local time and could even be felt as far away as Egypt. “Greece issues tsunami warning as 5.9 magnitude quake ‘felt in Egypt,’” reported LUMEN via The Independent, reflecting how widespread the impact was.

Although no major damage or injuries have been reported so far, the quake prompted authorities to urge both locals and visitors to move away from the coastline due to concerns about a possible tsunami. Social media quickly filled with firsthand videos showing just how intense the shaking really was.

So, why are there so many earthquakes happening in Greece right now?

Should we be concerned?

While the frequency and strength of recent quakes might seem unusual, there are solid geological reasons behind them. Greece sits in a particularly active seismic zone known as the Hellenic subduction zone.

This is where the African tectonic plate is slowly pushing underneath the Eurasian plate. That ongoing collision triggers thousands of small earthquakes each year—up to 25,000, in fact—many of which are too weak to be felt.

But there’s more to it. Scientists believe that climate change may also be playing a role in increasing seismic activity. Rising sea levels, shifting ocean temperatures, and more extreme weather events can alter pressure on the Earth’s crust. These changes may, in some cases, be enough to trigger small slips along fault lines that are already under stress.

Seismic Activity in Greece

Seismologist Dr. John Vidale from the University of Southern California explains that Greece's position on the complex boundary of the African and Eurasian tectonic plates leads to heightened seismic activity. His research indicates that while earthquakes are common, the recent uptick in activity could be attributed to geological adjustments rather than immediate threats to infrastructure or safety.

Moreover, Dr. Vidale emphasizes that travelers should remain informed but not fear, as modern buildings are constructed to withstand such events, enhancing overall safety for visitors.

Greece's tourism sector experienced unprecedented growth in 2024, welcoming a record 40.7 million international visitors—a 12.8% increase from the previous year. This surge generated €21.6 billion (approximately $24.3 billion) in revenue, solidifying tourism's role as a cornerstone of the Greek economy, contributing over a quarter to the nation's GDP.

Despite these positive trends, challenges such as overtourism have emerged, particularly in popular destinations like Santorini and Mykonos. Local authorities are considering measures like cruise ship visitor caps and disembarkation fees to manage the influx and preserve the islands' infrastructure and cultural heritage.

Still, while the recent activity has caught the attention of both scientists and travelers, there is no official travel advisory against visiting Greece. For now, you can still pack your bags and enjoy the islands. Just be aware that earthquakes are part of life in the region and may continue to become more frequent in the years ahead.

So yes, Greece is shaking a bit more than usual, but there’s no need to panic. It’s a reminder that the Earth is always moving, often in ways we can’t predict. Stay informed, follow local guidance, and you can still enjoy that much-needed getaway.

Travel safety expert Dr. Patricia O’Neill shares that understanding the local emergency protocols can empower travelers in earthquake-prone regions. She recommends visiting Ready.gov to familiarize oneself with safety measures, such as identifying safe spots and knowing evacuation routes.

Additionally, keeping a small emergency kit, including water and basic supplies, can be beneficial. Dr. O’Neill emphasizes that preparation not only enhances safety but also boosts confidence, allowing travelers to enjoy their experiences without undue worry.

In summary, while Greece’s seismic activity may raise concerns for travelers, expert insights affirm that understanding the geological context and being prepared can significantly mitigate risks. Dr. John Vidale and safety authorities like Dr. Patricia O’Neill advocate for informed travel, focusing on emergency readiness. This proactive approach not only enhances personal safety but enriches the travel experience, allowing visitors to immerse themselves in Greece's rich culture and stunning landscapes without fear.

As always, remaining updated on local conditions and following expert guidance can lead to a rewarding adventure in this beautiful region.
