A 5.7 magnitude earthquake struck Crete, followed by 51 recorded aftershocks. Earthquakes are common in this region due to its position along active tectonic fault lines, and Crete's building standards are designed with seismic activity in mind. Most structures, particularly modern hotels and tourist facilities, meet strict earthquake-resistant construction codes. Visitors currently on the island should remain calm and follow standard safety precautions: stay away from damaged buildings, avoid coastal areas immediately after a significant tremor as a precaution against any sea disturbance, and follow guidance from local authorities. Check with your accommodation for any specific instructions. Tourist sites and infrastructure are typically assessed quickly after seismic events. Monitor local news and official announcements for updates, and contact your hotel or tour operator if you have concerns about specific areas or activities.
