The Athens Geodynamic Institute said the first quake, with a 5.1 magnitude, hit at 4:11am local time (0111 GMT) about 47 kilometres (29 miles) northeast of the city of Sitia.

A second quake, with a magnitude of 5.2, struck the same point exactly three hours later, at 7:11am.

Greece is prone to earthquakes, with many occurring offshore.

The last deadly quake occurred in the island of Kos in the Aegean Sea in July 2017. The 6.7-magnitude quake killed two people.

The deadliest temblor in recent years struck the Athens region in 1999, killing 143 people.
