An earthquake with a magnitude of 5.1 on the Richter scale hit the popular Greek holiday island of Santorini in the early hours Saturday, causing residents and tourists to run out of their homes and hotels in a panic.

The epicentre of the quake was at sea. Two smaller earthquakes with a magnitude of 3.9 and 3.7 had struck the island earlier in the evening.

There were no immediate reports of injuries or damage.
