Tremors felt across Egypt
Northern Egypt’s coastal cities, including Alexandria and Port Said, experienced tremors from a 6.4-magnitude offshore quake linked to the Crete event. The National Research Institute of Astronomy and Geophysics reported the epicenter 431 kilometers off Egypt’s coast. No casualties or damage were recorded, but the shaking disrupted daily activities.
Egyptian authorities reassured residents, emphasizing robust monitoring systems. Fishing boats and tour operators were advised to remain cautious, with emergency teams on standby. The quake’s reach highlighted the interconnected seismic activity along the Hellenic Arc, a major fault zone influencing both Greece and Egypt.
Greece’s seismic vulnerability
Greece’s position on the African and Eurasian tectonic plates makes it one of Europe’s most earthquake-prone regions. The Hellenic Arc, stretching from the Ionian Sea to Turkey, generates frequent tremors. In the Cyclades, over 18,400 minor quakes were recorded between January 26 and February 13, 2025, raising concerns among sismologists.
Crete alone averages 1,900 quakes annually, though most are below magnitude 3.0. Major events, like the 6.3-magnitude quake in October 2021, have shaped Greece’s rigorous safety protocols. Reinforced buildings and public education campaigns have minimized casualties, as seen in the latest quake’s lack of reported damage.
- Annual quakes: Approximately 1,900 in Crete.
- Recent activity: 18,400 minor quakes in Cyclades.
- Safety measures: Reinforced buildings, public drills.
Impact on tourism
The earthquake disrupted Crete’s tourism sector, a vital economic driver hosting over 3 million visitors yearly. Coastal evacuations and the tsunami warning led to temporary closures of beaches and waterfront restaurants. Airports in Heraklion and Chania remained operational, but some flights faced delays for runway inspections.
The UK Foreign Office advised travelers to monitor local updates and avoid coastal areas during alerts. No widespread cancellations were reported, but tour operators reinforced safety protocols. Hotels conducted evacuation drills, ensuring guest safety, while the Greek tourism ministry emphasized the region’s resilience.
