A new jolt struck Bulgaria's capital Sofia Wednesday morning, shaking apartment buildings and reviving fearful memories of last week's strong quake.
The quake occurred at 8.:37 am local time and had a magnitude of 3.2-3.3 on the Richter scale.
The epicenter of the aftershocks was located some 20-25 southwest of Sofia, close to the epicenter of the shallow tremor that threw people into panic earlier this week.
A strong 5.9-magnitude quake struck south-west of Bulgaria's capital Sofia shortly after 3.00 am (00.00 GMT) last Tuesday. Even though the jolt made no casualties, it shook apartment buildings and caused people to rush out into the streets in the middle of the night.
Researchers from the Bulgarian Academy of Sciences have explained that aftershocks may reach a magnitude of 4 on the Richter scale, which would not damage the infrastructure. However, objects may fall and injuries may occur.
Unlike previous aftershocks, this time the depth of the jolt was registered at just 15 kilometers beneath the earth surface, which is the reason why it was felt strongly in the capital Sofia and the nearby town of Pernik.
