A magnitude 5.7 earthquake struck Crete, prompting a public warning from seismologist Akis Tselentis urging people to stay away from the coastline due to the risk of a seismic sea wave (tsunami). The tremor was significant enough to draw an official safety response. Tourists currently on the island should move away from beaches and low-lying coastal areas immediately after any strong shaking and wait for official confirmation that it is safe to return. Do not re-enter the water until local authorities give the all-clear. Monitor local emergency broadcasts and your accommodation's staff for updates. Earthquakes are not uncommon in Crete given its location on active fault lines, but following coastal evacuation guidance quickly is the most important precaution visitors can take during such events.
