A 6.6 magnitude earthquake struck off the west coast of Cyprus early Tuesday, the United States Geological Survey said.
The strong and relatively shallow quake was centered 48 kilometers (30 miles) west-northwest of the city of Polis on the Mediterranean island, the USGS said.
There was a low probability of casualties and damage from the earthquake, the USGS said in its preliminary assessment.
Cyprus is in a secondary earthquake-prone area, but tremors of this magnitude are rare.
The largest earthquake in recent years was a magnitude 6.8 in 1996, killing two people in Paphos on the west coast.
