An earthquake measuring 4.9 on the Richter scale occurred late Saturday in Vrancea seismic zone, eastern Romania, according to the National Institute for Earth Physics (INFP).

This is the largest earthquake recorded in the country in the current year.

The quake occurred at a depth of 150 km, rocking a mountainous area of Buzau County, some 150 km northeast of the capital of Bucharest.

The quake was last one in the day when another four measuring between 2.9 to 4.3 degrees on the Richter scale hit the same region.

There is no report of casualty for now.

More than 50 felt earthquakes have taken place in Vrancea seismic zone this year, seven of them measuring over 4 and less than 5 degrees on the Richter scale.

An earthquake measuring 5.5 magnitudes on the Richter scale jolted Vrancea region on October 6, 2013 and another eight quakes measuring over 4 and less than 5 degrees on the Richter scale hit the same region in the last year.

Vrancea seismic zone, including counties of Vrancea and Buzau, is one of the most active seismic areas in Europe. It is known for its intermediate-depth (70-200 km) earthquakes, which can reach a magnitude of 7.0 to 7.8.

In March 1977, a 7.6-magnitude earthquake killed 1,600 people in Romania and damaged 8,500 buildings.
