In the early hours of May 14, 2025, a powerful earthquake jolted the island of Crete, Greece, sending shockwaves across the region and prompting tsunami warnings. Residents in nearby countries, including Israel and Egypt, reported feeling the tremors, highlighting the quake's extensive reach.

📍 Epicenter Details: Where and How It Happened

  • Magnitude: 6.3 (Geodynamic Institute of Athens); 6.1 (US Geological Survey)

  • Depth: Approximately 62.5 km to 83 km

  • Location: Near the Aegean island of Kasos, south of Crete

  • Time: 22:51 UTC on May 13 (01:51 local time, May 14)

The quake's depth played a crucial role in mitigating potential damage, as deeper earthquakes tend to have less surface impact. 

🚨 Immediate Aftermath: Tsunami Alerts and Public Response

Shortly after the quake, authorities issued tsunami warnings for southern Greece, advising residents in coastal areas to stay alert and move to higher ground if necessary. Emergency alerts were dispatched to residents in Crete, Rhodes, Kos, and other southeastern Aegean islands. 

Despite the quake's strength, initial reports indicated no significant damage or injuries, largely due to its depth and offshore epicenter. 

🌐 Regional Impact: Tremors Felt Beyond Greece

The earthquake's effects were not confined to Greece. Residents in Israel, particularly in Tel Aviv and Jerusalem, reported feeling the tremors, with local geological surveys recording magnitudes between 2.0 and 2.3. 

In Egypt, the National Research Institute of Astronomy and Geophysics noted the quake but reported no casualties or property damage. 

🧠 Understanding the Seismic Activity: Why Crete?

Crete lies in one of Europe's most seismically active zones, where the African and Eurasian tectonic plates converge. This geological setting makes the region prone to earthquakes. 

Earlier this year, the Santorini-Amorgos zone experienced a swarm of approximately 7,700 tremors over a short period, raising concerns about increased seismic activity in the region. 

🛡️ Safety Measures: What Residents Should Do

  • Stay Informed: Keep up with official updates from local authorities and geological institutes.

  • Emergency Kits: Prepare kits with essentials like water, food, medications, and flashlights.

  • Evacuation Plans: Know the evacuation routes and have a plan in place.

  • Structural Checks: Ensure your home or building is structurally sound and meets safety standards.

🔄 Looking Ahead: Aftershocks and Ongoing Monitoring

While no significant aftershocks have been reported, authorities continue to monitor the situation closely. Residents are advised to remain vigilant, as aftershocks can occur days or even weeks after the initial quake.

FAQ

The earthquake resulted from the movement of the African and Eurasian tectonic plates, which converge near Crete, making the region seismically active.

A tsunami warning was issued as a precaution, but no significant tsunami was reported.

Aftershocks are common following significant earthquakes. Residents should stay alert and follow official guidance.

Have an emergency kit ready, know evacuation routes, and ensure your home meets safety standards.

Initial reports indicate no significant damage or injuries, likely due to the quake's depth and offshore location.

The earthquake's magnitude and depth allowed its seismic waves to travel long distances, reaching neighboring countries like Israel and Egypt.

Yes, Crete is located in a seismically active region due to the convergence of tectonic plates.

Drop to the ground, take cover under sturdy furniture, and hold on until the shaking stops.
