DHAKA: A strong magnitude 6.1 earthquake struck off western Greece early on Monday.

The United States Geological Survey said, reports The Straits Times.

The quake, which was initially reported as 6.4 in magnitude, struck 122km west of Patras at a relatively shallow depth of 13.7km at 0308 GMT, the USGS said.

There were no immediate reports of injuries or damage.

A 5.8-magnitude earthquake struck the same region late last month. That quake was felt on several Ionian islands and as far away as the capital Athens.
