BUCHAREST, Sept. 3 (Xinhua) -- An earthquake with a magnitude of 4.5 on the Richter scale occurred on Tuesday afternoon in Buzau County, southeast of Romania, announced the National Institute for Earth Physics.
It was the strongest earthquake this year, and the third one this month.
The epicenter of the earthquake, with a depth of 117 km, was determined to be near Nehoiu, some 120 km northeast of Bucharest, the capital of the country.
There were no immediate reports of injuries in the epicenter area.
Other nine seismic events of over magnitude 4.0 took place in Romania this year.
The Vrancea seismic zone, including the eastern counties of Vrancea and Buzau, as well as surrounding mountains, 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 major earthquake killed over 1,000 people in Romania and damaged thousands of buildings.
