6.1-magnitude earthquake hits Crete: Tsunami warning and safety tips

A 6.1-magnitude earthquake struck Crete early on May 22, 2025. The quake lasted about 40 seconds and woke many people, including tourists. British holidaymakers said they felt scared and shared their experiences online.

The quake’s center was 79 kilometers from Heraklion, the island’s capital. It happened at a depth of 68 kilometers. After the quake, experts warned of a possible tsunami. They asked people to move away from the coast and go to higher ground.

The European-Mediterranean Seismological Centre said, “Depending on the distance from the coast, the tsunami could be local, regional, or distant.” Greek officials told residents to stay alert but not to panic.

Experts say you can spot a tsunami by watching for some signs. These include strong shaking from the earthquake, water suddenly pulling away from the shore, and a loud roaring noise like a train or airplane. The American Geosciences Institute advises, “If you see these signs, don’t wait for official orders. Move to higher ground immediately.”

In Crete, the earthquake caused damage to roads and old buildings. Shops shook, and many products fell off shelves. People quickly left their homes for safety. So far, no serious injuries have been reported.

Since the quake, Crete has felt five smaller aftershocks. The strongest aftershock was 3.5 magnitude. Vasilis Karastathis, director of the Geodynamic Institute of Athens, said, “It may take a few days to fully understand the impact.” He added, “We do not expect major damage or a big tsunami.”

Crete sits where two tectonic plates meet. This area often has earthquakes. Local fire brigades are ready to respond to emergencies. Authorities have blocked some coastal areas to keep people safe.

British tourists said the earthquake scared them. One said, “It was the scariest moment of my life.” Another added, “The whole ground was shaking like jelly.”

Officials keep watching the situation. They remind people to have an emergency plan and keep disaster supplies ready. This event shows why it is important to know the signs of earthquakes and tsunamis.

Crete has over 600,000 residents, with about one-third living in Heraklion. People on the island stay alert as experts watch for more aftershocks and work to keep everyone safe.
