An earthquake of 3.3 on the Richter scale shook the town of Pernik, about 33km from Bulgaria’s capital city Sofia, at 4.54am on May 6 2014, seismological records showed.
The epicentre of the jolt, at a depth of two km, was close to the epicentre of the destructive May 22 2012 earthquake that hit Pernik.
The May 6 2014 quake was followed by two aftershocks and more were expected, seismologists said. No injuries or damage were reported.
The 5.6 Richter scale earthquake epicentred about nine km outside Pernik on May 22 2012 damaged an estimated 60 per cent of the houses in the Bulgarian mining town and caused damage of about 20 million leva (about 10 million euro). The government voted considerable sums towards repairs, but there were continuing complaints and protests about tardiness in granting funds for repairs and the bureaucratic process for granting assistance.
