An 4.5-magnitude earthquake shook central Bulgaria on Friday but there were no reports of any injuries or damage.

The quake occurred just after 2 p.m. local time (1101 GMT) in the Balkan nation. Its epicenter was 10 kilometers (6 miles) north of Bulgaria's second largest city of Plovdiv at a shallow depth of two kilometers (slightly over one mile), according to the National Geophysical Institute.

The temblor was followed by a series of minor aftershocks and was felt in the capital, Sofia, and elsewhere in the Balkan country.
