ATHENS — An earthquake with a preliminary magnitude of 5.4 rattled the eastern Greek island of Rhodes overnight, followed by a quake of 4.6 on Monday morning. No damage or injuries were reported from either.

The Athens Geodynamic Institute said the first quake occurred on Sunday night just before 9 p.m. and with an epicenter 30 kilometers (18 miles) north of Rhodes. 

The second struck Monday morning just after 7 a.m. with an epicenter near the first quake, 26 kilometers (16 miles) north northeast of the island. 

Greece lies in a highly seismically active region of the world, and earthquakes are common. The vast majority do not cause any injuries or significant damage.
