The earthquake registered last night in the area of Belitsa was a micro earthquake, which is not unusual for the region, Prof. Emil Botev, who heads of the Seismology department at the National Institute of Geophysics, Geodesy and Geography to the Bulgarian Academy of Sciences, told Focus News Agency
. The quake was registered shortly before midnight 11 km northwest of the town of Belitsa and 74 km south of Sofia, in the Rila National Park, at a depth of 10 km. The higher seismic activity is usual for the mountainous regions, Prof. Botev explained, adding that particularly in Rila at least 1,000 similar earthquakes were registered in the last 30 years. The one last night can be compared with a slight tremble caused by a heavy truck, for example, he said.
